In 1912, geophysicist Alfred Wegener proposed the theory of continental drift, suggesting that Earth's continents were once joined in a single supercontinent. For decades, Wegener's hypothesis was widely dismissed by the scientific community due to the lack of a known physical mechanism that could move landmasses. ______ in the 1950s and 1960s, the discovery of seafloor spreading provided the geological evidence required to validate his ideas, paving the way for the acceptance of plate tectonics.

Which choice completes the passage with the most logical transition?

Cevabı ve açıklamayı göster

Cevap: Subsequently,

Cevap

Subsequently,
The transition 'Subsequently' is correct because it logically connects the chronological events in the passage. The passage first describes Alfred Wegener's 1912 proposal and the decades of skepticism that followed, and then transitions to a later event in the 1950s and 1960s (the discovery of seafloor spreading) that validated his ideas. 'Subsequently' correctly signals that this validation occurred after the initial proposal and dismissal.

Adım Adım Çözüm

1
Analyze the chronological relationship between the events in the text.
The first sentence sets the starting point of the timeline in 1912 (Wegener's proposal). The second sentence describes the following 'decades' of rejection. The final sentence introduces a later period: 'the 1950s and 1960s'.
Identifying the dates and sequence of events establishes the temporal flow of the passage.
2
Determine the direction of the chronological sequence.
The event in the blank sentence (the discovery of seafloor spreading in the 1950s and 1960s) occurred after the 1912 proposal and the decades of rejection.
Establishing that the second event occurs later in time indicates a sequential relationship.
3
Select the transition word that conveys an event occurring after another in time.
'Subsequently' is the only option that denotes an event happening later in a sequence.

Cevap

The correct sequence of the sentences is: first, rainwater absorbs carbon dioxide and becomes acidic; second, this acidic water percolates downward and dissolves bedrock; third, underground cavities grow too large to support the surface; and fourth, the surface collapses to create a sinkhole.
The correct order follows the natural physical progression of sinkhole formation: first, rainwater becomes acidic; second, that specific acidic water percolates and dissolves bedrock; third, cavities grow larger over time; and fourth, the surface collapses as a consequence of the unsupported cavities. The transition words 'then', 'Eventually', and 'Consequently', along with the referring phrase 'This acidic water', reinforce this sequence.

Adım Adım Çözüm

1
Identify the introductory sentence that establishes the initial cause of the sequence.
The sentence about rainwater absorbing carbon dioxide to turn acidic is identified as the start of the sequence.
It does not rely on any preceding context or pronouns and establishes the source of the acidity needed for the subsequent steps.
2
Look for transition words and pronoun referents that connect to the initial sentence.
The sentence beginning with 'This acidic water then percolates...' is placed second.
The phrase 'This acidic water' directly references the result of the first sentence, and the transition 'then' denotes the next step in the physical process.
3
Trace the logical progression of cause and effect in the dissolution of subterranean rock.
The sentence starting with 'Eventually, the underground cavities...' is placed third.
The creation of 'underground cavities' is the logical long-term consequence of the percolation and dissolution described in the second step, indicated by the time transition 'Eventually'.
4
Identify the final outcome or culmination of the sequence.
The sentence starting with 'Consequently, the surface suddenly collapses...' is placed last.
The transition 'Consequently' signals the direct result of the cavities becoming too large to support the surface weight, concluding the process of sinkhole formation.

During a submarine volcanic eruption, magma erupts from fissures on the ocean floor and cools rapidly upon contact with seawater, building up layers of basaltic rock. Over thousands of years, repeated eruptions accumulate enough material to breach the ocean surface. _______, wind and waves carry seeds to the newly formed island, initiating the colonization of terrestrial plant life.

Which choice completes the text with the most logical transition?

Cevabı ve açıklamayı göster

Cevap: Afterward

Cevap

Afterward
The correct transition is the word meaning subsequent in time. The passage describes a sequence of geological and biological events: first, underwater volcanic activity builds up rock layers; second, the island rises above the sea surface; third, wind and waves carry seeds to the new land. The transition 'Afterward' logically signals this subsequent stage in the timeline.

Adım Adım Çözüm

1
Analyze the relationship between the sentences.
The first two sentences describe the formation of a volcanic island over thousands of years. The final sentence describes the arrival of seeds to this newly formed landmass.
Understanding the logical connection between the ideas is necessary to select the correct transition word.
2
Determine the chronological order of the events.
The island must first breach the ocean surface before seeds can be carried to it. The arrival of seeds is a subsequent event in the timeline.
This establishes that a chronological or sequential transition indicating a subsequent event is required.
3
Evaluate the transition choices.
'Afterward' correctly signals that the seed arrival happens after the island's formation. 'Previously' reverses this order, 'In contrast' incorrectly implies opposition, and 'Furthermore' indicates addition rather than sequence.
This allows us to identify the transition that fits the chronological flow of the passage.

Cevap

The correct sequence of sentences is: first, the sentence introducing Lady Montagu and the practice of variolation; second, the sentence describing Edward Jenner's 1796 hypothesis; third, the sentence explaining the experiment to test this hypothesis; and finally, the sentence concluding with the global eradication of smallpox in 1980.
The correct order follows a clear chronological progression (from the early eighteenth century to 1796, then to the testing phase, and finally to the long-term impact in 1980) and respects pronouns and determiners ('this hypothesis' and 'this pioneering experiment') that link sentences together.

Adım Adım Çözüm

1
Identify the chronological and logical starting point of the narrative.
The sentence introducing Lady Mary Wortley Montagu is identified as the first sentence.
It introduces the earliest time frame ('early eighteenth century') and the foundational concept of 'variolation' which subsequent sentences refer to.
2
Identify the subsequent chronological event that builds on the first.
The sentence beginning 'Decades later, in 1796' is identified as the second sentence.
The transition 'Decades later' links it chronologically to the eighteenth century, and its comparison to the risks of 'variolation' logically requires the concept to have been introduced beforehand.
3
Link the hypothesis to its direct experimental application.
The sentence starting with 'To test this hypothesis' is identified as the third sentence.
The demonstrative pronoun phrase 'this hypothesis' refers back to the hypothesis formulated by Edward Jenner in the second sentence, and it describes the execution of the experiment.
4
Determine the final conclusion or long-term consequence of the sequence.
The sentence starting with 'Ultimately, this pioneering experiment' is identified as the fourth sentence.
The transition 'Ultimately' signals a concluding outcome, 'this pioneering experiment' refers back to the trial in the third sentence, and the year '1980' marks the final point on the timeline.

For years, their theoretical calculations remained unverified due to the limitations of observational technology. _______ in 1964, radio astronomers Arno Penzias and Robert Wilson detected this faint hum of radiation while testing a sensitive horn antenna, providing the first empirical proof of the prediction.

Which choice completes the passage with the most logical transition?

Cevabı ve açıklamayı göster

Cevap: Eventually,

Cevap

Eventually,
The correct choice is 'Eventually,' because it logically indicates that the discovery of cosmic microwave background radiation in 1964 occurred after a long period of time and scientific progress following the 1948 prediction.

Adım Adım Çözüm

1
Analyze the chronological sequence of events in the passage.
The timeline begins in 1948 with a theoretical prediction. This is followed by a period of years in which the calculations remained unverified. The final event occurs in 1964 with the empirical detection of the radiation.
Understanding the timeline is necessary to determine the chronological relationship between the sentences.
2
Identify the relationship indicated by the transition.
The transition needs to connect the long period of unverified theory to the subsequent empirical discovery that occurred years later.
Selecting the correct transition requires matching the logical connection of the events with a transition that signals the passage of time leading to a subsequent event.
3
Evaluate the choices to find the transition that indicates chronological progression over time.
'Eventually' is a chronological transition that signals an event occurring after a long delay or series of events. Other transitions signal addition, opposition, or an initial state, which do not fit the chronological context.
This determines the final correct option by eliminating incorrect relationships.

The correct sequence begins with the introduction of Fritz Zwicky's initial proposal in the 1930s, followed by the community's multi-decade dismissal of his hypothesis, then the pivotal corroborating evidence presented by Vera Rubin and Kent Ford in the 1970s, and finishes with the scientific community's subsequent acceptance and theoretical modeling.
The correct order follows a clear chronological progression. The sequence begins with the earliest event in the 1930s (Zwicky's initial proposal). It then describes the immediate historical reception, noting that the community 'initially dismissed' it for 'several decades.' The narrative continues with the resolution of this skepticism in the 1970s ('The tide turned...'), and concludes with the direct consequence of that discovery ('Following Rubin and Ford's empirical confirmation... subsequently began...').

Adım Adım Çözüm

1
Identify the introductory sentence.
The sentence describing Fritz Zwicky's observation in the 1930s is the logical starting point because it introduces the primary concept (dark matter) and the earliest timestamp.
Chronological narratives must establish the initial condition or discovery before tracking its evolution over time.
2
Connect the initial event to its immediate historical aftermath.
The sentence starting with 'Despite Zwicky's groundbreaking observations' directly references the preceding event and describes the reception of the theory over the subsequent 'several decades.'
The pronoun reference and contrast transition link this sentence directly as the second step in the sequence.
3
Locate the turning point that resolves the initial period of dismissal.
The sentence mentioning that 'The tide turned in the 1970s' logically follows the decades of dismissal, introducing Rubin and Ford's galactic rotation curve findings.
The 1970s timestamp chronologically succeeds the 1930s and the subsequent decades of stagnation.
4
Identify the concluding impact and subsequent research developments.
The sentence starting with 'Following Rubin and Ford's empirical confirmation' establishes the final phase, wherein cosmologists accepted the theory and 'subsequently' built simulations.
This sentence relies on the empirical confirmation described in the previous step and outlines the modern consensus and application.

In 1845, English mathematician John Couch Adams calculated the coordinates of this hypothetical planet, though his findings were initially shelved by colleagues. ___________, French astronomer Urbain Le Verrier independently published his own mathematical predictions in 1846, leading directly to the observational discovery of Neptune by Johann Gottfried Galle.

Which choice completes the text with the most logical transition?

Cevabı ve açıklamayı göster

Cevap: Subsequently

Cevap

Subsequently
The correct option is the word that indicates that one event happened after another. The passage details two key calculations in the search for Neptune: John Couch Adams's calculations in 1845, followed by Urbain Le Verrier's predictions in 1846. The transition word 'Subsequently' correctly denotes that Le Verrier's publication occurred after Adams's calculations.

Adım Adım Çözüm

1
Analyze the context and timing of the two main events in the passage.
The first event is John Couch Adams calculating the coordinates of the hypothetical planet in 1845. The second event is Urbain Le Verrier publishing his own predictions in 1846.
Identifying the chronological relationship between the events (1845 followed by 1846) is necessary to determine the correct sequential transition.
2
Evaluate the transition word that best connects these sequential events.
A transition indicating subsequent action or chronological progression is needed to bridge the events of 1845 and 1846.
This establishes a logical flow indicating that the second event followed the first in time.
3
Test the options against the identified chronological relationship.
The word 'Subsequently' correctly signals that Le Verrier's 1846 work came after Adams's 1845 calculations. Options like 'Previously' and 'Simultaneously' distort the chronological timeline, while 'Nevertheless' incorrectly introduces a contrast relationship.
This confirms the correct transition choice and eliminates incorrect alternatives.

The correct sequence begins with the discovery of penicillin in 1928, followed by the research plateau and the subsequent involvement of the Oxford team, then the purification of the compound for animal trials, and finally the transition to industrial mass production in collaboration with American factories.
The correct sequence begins with the discovery of penicillin in 1928. It then transitions to the decade-long research plateau that followed, which was ended by the Oxford team's work. Once the Oxford team focused on the compound, they purified and stabilized it for animal trials. Finally, the successful animal trials allowed researchers to collaborate with American factories to scale up mass production.

Adım Adım Çözüm

1
Identify the initial event that establishes the topic and timeline.
The sentence introducing Alexander Fleming's 1928 discovery of penicillin establishes the baseline context.
Chronologically and logically, the initial discovery must precede any subsequent research efforts or production scales.
2
Look for transitions or cohesive devices linking to the initial discovery and its limitation.
The sentence describing the 'decade-long research plateau' connects directly to the inability to isolate the compound mentioned in the first sentence.
The phrase 'This decade-long research plateau' functions as an anaphoric reference to the stagnation following the 1928 discovery, marking the next chronological phase starting in the late 1930s.
3
Identify the logical next step of the Oxford team's research program.
The sentence starting with 'After purifying and stabilizing the compound' describes the immediate outcome of the Oxford team's focus.
Before conducting animal trials, the team first had to solve the instability issue mentioned in previous sentences, making this step logically prior to testing and manufacturing.
4
Determine the final phase of the process.
The sentence detailing the scale-up to mass production in collaboration with American factories concludes the sequence.
Mass production and industrial scaling naturally follow successful therapeutic validation in laboratory animal trials.

The correct sequence begins with Friedrich Miescher's 1869 isolation of nuclein, followed by Oswald Avery's 1944 proof of its genetic role, followed by Erwin Chargaff's 1950 discovery of base ratios, and concluding with Watson and Crick's 1953 double-helix model.
The logical sequence is defined by both dates and explicit transitions: the sequence starts in 1869 ('First'), transitions to 1944 ('Decades later'), connects to 1950 ('Following this discovery'), and concludes in 1953 ('Ultimately') with Watson and Crick's model which synthesized the earlier clues.

Adım Adım Çözüm

1
Identify the sentence that initiates the sequence.
The sentence starting with 'First' describes the earliest event (1869) and introduces the substance 'nuclein'.
Transition words like 'First' and chronological order require the earliest date to lead the sequence.
2
Locate the logical transition referring back to the initial substance.
The sentence starting with 'Decades later' describes the 1944 demonstration that 'this substance' (referring back to Miescher's nuclein) is the genetic carrier.
The pronoun phrase 'this substance' must refer back to a previously introduced noun, linking the 1869 event to the 1944 event.
3
Trace the consequence of the 1944 discovery.
The sentence starting with 'Following this discovery' links Chargaff's 1950 base ratio observations directly to the 1944 identification of DNA as the genetic carrier.
'Following this discovery' connects the timeline sequentially from 1944 to 1950.
4
Determine the concluding event.
The sentence starting with 'Ultimately' details the construction of the double-helix model in 1953 using the previously mentioned 'clues'.
The word 'Ultimately' signals the final step in a process, and 1953 represents the latest point on the timeline.

Cevap

The correct sequence begins with Marie Tharp plotting raw sonar data in the early 1950s, followed by her noticing a V-shaped cleft while analyzing those profiles, then Bruce Heezen initially dismissing the finding as a drafting error, and ending with Heezen subsequently plotting earthquake epicenters to validate the mapping.
The correct chronological and logical sequence begins with the initiation of the mapping project in the early 1950s, followed by the discovery of the cleft while analyzing the mapping profiles, then the initial skepticism of Tharp's research partner, and finally the subsequent verification of the cleft through earthquake epicenter mapping.

Adım Adım Çözüm

1
Identify the introductory sentence that establishes the broad context and timeframe.
The sentence introducing Marie Tharp plotting raw sonar data in the early 1950s is placed first.
It establishes the chronological starting point and introduces the sonar data referenced later.
2
Locate the sentence that builds directly on the introduction by referencing the plotted sonar profiles.
The sentence starting with 'While analyzing these profiles' is placed second.
The phrase 'these profiles' points back to the 'raw sonar data' in the first sentence, and it introduces the finding of the V-shaped cleft.
3
Identify the immediate response to the discovery of the cleft.
The sentence starting with 'Initially, her research partner...' is placed third.
'Initially' indicates the first response to the hypothesis proposed in the second sentence, establishing the initial skepticism.
4
Determine the final resolving action in the sequence.
The sentence starting with 'Shortly thereafter, Heezen plotted...' is placed fourth.
'Shortly thereafter' transitions to the subsequent action that validates the findings and resolves the skepticism.

In 1856, eighteen-year-old chemist William Henry Perkin was attempting to synthesize quinine, a treatment for malaria, when his experiment went awry and produced a dark, sticky sludge. As he was cleaning his flask with alcohol, however, he noticed that the substance left a brilliant purple residue on the glass. _______ he patented this new substance as 'mauveine'—the world's first synthetic dye—and launched the modern chemical industry.

Which choice completes the passage with the most logical transition?

Cevabı ve açıklamayı göster

Cevap: Subsequently,

Cevap

The transition 'Subsequently' is the correct choice because it logically connects the chronological steps of Perkin noticing the residue and then patenting it.
The passage describes a sequence of events: first, Perkin noticed a purple residue while cleaning his flask; next, he patented the substance and launched an industry. The transition 'Subsequently' is correct because it logically signals a subsequent step in a chronological sequence.

Adım Adım Çözüm

1
Analyze the relationship between the sentences before and after the blank.
The sentence before the blank describes Perkin noticing a purple residue. The sentence with the blank describes him patenting the substance and starting an industry.
Understanding the connection between these events determines the appropriate category of transition word.
2
Identify the chronological order of the actions.
Noticing the residue happened first. Patenting the substance occurred after this discovery.
A sequential or chronological transition is needed to show that the second event followed the first.
3
Evaluate the choices to find the one that establishes a subsequent chronological relationship.
'Subsequently' correctly indicates that the patenting occurred after the discovery. Other options represent incorrect relationships like reverse chronology, contrast, or exemplification.
Selecting the correct transition ensures the text flows logically and accurately represents the historical timeline.
