Cevabı ve açıklamayı göster

Cevap

A colon (:) or an em dash (—) is the correct punctuation mark to connect the independent clause to the list.
The clause before the blank is grammatically independent, whereas the phrase after the blank is a list of noun phrases identifying the specific brain regions. A colon or a single em dash is the standard convention to link an independent clause to an explanatory list or definition that follows it. In this context, it properly introduces the 'two distinct regions' without creating grammatical fragmentation.

Adım Adım Çözüm

1
Evaluate the clause preceding the blank.
The clause 'When human brains process language, two distinct regions in the left hemisphere are activated' is grammatically independent because it contains a subject and a verb and forms a complete thought.
Determining whether the first clause is independent is necessary to apply the rules of colons, semicolons, and dashes.
2
Evaluate the structure of the phrase following the blank.
The phrase 'Broca's area... and Wernicke's area...' is a list of noun phrases containing internal commas, not an independent clause.
Since the second part cannot stand alone as a sentence, a semicolon cannot be used.
3
Select the correct punctuation mark that links an independent clause to a list.
A colon or a single em dash is correct because both can join an independent clause to an explanatory list or appositive.
A colon or an em dash serves to signal that details explaining the 'two distinct regions' are immediately following.

Cevabı ve açıklamayı göster

Cevap

A semicolon, a colon, or an em dash must be used to link the two independent clauses.
The punctuation mark must connect two independent clauses where the second clause details or explains the first. A semicolon is correct because it links two closely related independent clauses. A colon is also correct because the clause preceding it is independent and the second clause illustrates the first. An em dash is also acceptable as it can join an independent clause with explanatory details.

Adım Adım Çözüm

1
Analyze the grammatical structure of the clause preceding the blank.
The clause 'In the mid-twentieth century, artist Ruth Asawa began creating intricate wire sculptures that challenged traditional definitions of sculpture' contains a subject ('artist Ruth Asawa') and a verb ('began') and expresses a complete thought, making it an independent clause.
Identifying clause boundaries is necessary to determine the correct punctuation.
2
Analyze the grammatical structure of the clause following the blank.
The clause 'she crocheted industrial wire into looping, three-dimensional forms that appeared weightless and transparent' also contains a subject ('she') and a verb ('crocheted') and expresses a complete thought, making it a second independent clause.
Determining if the second clause is independent narrows down the choice of punctuation marks.
3
Evaluate the relationship between the two independent clauses to select the correct punctuation.
Since the second clause explains or illustrates how Asawa's sculptures challenged traditional definitions, they can be joined by a semicolon, a colon, or an em dash.
Semicolons, colons, and dashes are grammatically valid marks for connecting closely related independent clauses.

Cevabı ve açıklamayı göster

Cevap

A semicolon should be used to connect the two independent clauses.
A semicolon is the correct punctuation mark because it links two closely related independent clauses ('In historical linguistics, the comparative method is used to reconstruct extinct protolanguages by comparing cognates from daughter languages' and 'this systematic approach allows researchers to map out language families and trace human migration patterns across centuries') that are not joined by a coordinating conjunction.

Adım Adım Çözüm

1
Analyze the clause before the blank.
The clause 'In historical linguistics, the comparative method is used to reconstruct extinct protolanguages by comparing cognates from daughter languages' contains a subject ('the comparative method') and a verb ('is used'), making it a grammatically independent clause.
To determine the correct punctuation, we must first establish the grammatical status of the text surrounding the blank.
2
Analyze the clause after the blank.
The clause 'this systematic approach allows researchers to map out language families and trace human migration patterns across centuries' also contains a subject ('this systematic approach') and a verb ('allows'), making it another independent clause.
Identifying the structure of the second clause tells us how it must relate to the first clause.
3
Determine the appropriate punctuation to join two independent clauses without a coordinating conjunction.
A semicolon (;) is the standard punctuation mark used to link two independent clauses that are not joined by a coordinating conjunction (such as 'and' or 'but').
Using a comma would result in a comma splice, while a colon is inappropriate because the second clause does not explain or list elements of the first.

Cevabı ve açıklamayı göster

Cevap

A colon or a dash (such as an em dash)
A colon or a dash is correct because the clause preceding the blank is independent ('In his 1912 treatise... cognitive faculties') and the text following the blank is an explanation or list that elaborates on the 'two distinct cognitive faculties' mentioned. A colon or a single dash is standardly used to separate an independent clause from an explanatory list or phrase.

Adım Adım Çözüm

1
Analyze the grammatical structure of the clause preceding the blank.
The clause 'In his 1912 treatise on the philosophy of science, Henri Poincaré argued that mathematical discoveries are driven by two distinct cognitive faculties' is independent because it contains a subject ('Henri Poincaré') and a verb ('argued') and can stand alone as a complete sentence.
Identifying whether the preceding clause is independent is necessary to determine which punctuation marks (such as colons, semicolons, or dashes) are grammatically permissible.
2
Analyze the grammatical structure of the phrase following the blank.
The phrase 'logical analysis, which provides rigor and certainty, and creative intuition, which enables synthesis and invention' is a list of two non-independent noun phrases with nonessential clauses attached to them.
Identifying the structure of the following phrase determines the relationship between the two parts of the sentence and rules out punctuation marks that require an independent clause on both sides.
3
Choose the appropriate punctuation mark to link the independent clause to the explanatory list.
A colon or a dash is correct because both can join an independent clause to a list or explanation. A semicolon is incorrect because a semicolon must separate two independent clauses.
Applying standard English punctuation rules ensures that the transition between the independent clause and the elaboration is grammatically sound.

In his pioneering mid-twentieth-century analysis of language acquisition, linguist Noam Chomsky argued that human children do not merely memorize phrases but possess an innate capacity for grammar ___ an internal system of rules—often referred to as 'universal grammar'—that allows them to generate an infinite number of novel sentences. This theoretical framework revolutionized cognitive science by shifting the focus from behavioral imitation to underlying mental structures.

Which choice completes the text so that it conforms to the conventions of Standard English?

Cevabı ve açıklamayı göster

Cevap: grammar: an

Cevap

The correct answer is the option that uses a colon followed by 'an' ('grammar: an').
The correct option uses a colon to separate the independent clause from the explanatory appositive noun phrase. A colon must follow an independent clause and is used to introduce an explanation, list, or definition. In this sentence, the clause before the blank is independent, and the noun phrase after it explains what Chomsky meant by 'grammar'. Furthermore, using a colon avoids the structural confusion that would arise from using a dash, which would conflict with the pair of dashes already present later in the sentence.

Adım Adım Çözüm

1
Analyze the clause preceding the blank to determine if it is independent or dependent.
The clause 'In his pioneering mid-twentieth-century analysis of language acquisition, linguist Noam Chomsky argued that human children do not merely memorize phrases but possess an innate capacity for grammar' contains a main subject ('linguist Noam Chomsky') and a verb ('argued') and expresses a complete thought, meaning it is independent.
This step is necessary because colons, semicolons, and single dashes all require an independent clause before them.
2
Examine the grammatical structure of the phrase following the blank.
The segment 'an internal system of rules—often referred to as 'universal grammar'—that allows them to generate an infinite number of novel sentences' is a noun phrase appositive explaining 'grammar'. It does not contain an independent main clause.
This step helps eliminate the semicolon, which is only used to connect two independent clauses.
3
Identify potential conflicts with existing punctuation in the sentence.
The noun phrase already contains a nonessential parenthetical element ('often referred to as 'universal grammar'') set off by a pair of dashes. Using a single dash at the blank would introduce a third dash, creating a confusing and ungrammatical sequence.
This step helps eliminate the single dash option due to punctuation asymmetry and structural conflict.
4
Select the correct punctuation mark that fits the structural requirements.
A colon is the correct choice because it follows an independent clause, introduces an explanatory noun phrase, and does not conflict with the existing dashes.
This step finalizes the selection of the correct option.

In their ongoing study of ancient Martian topography, planetary scientists have noted that the planet's rugged southern highlandsa heavily cratered, ancient region that preserves the crustal signatures of the early solar system—stand in stark contrast to the smooth, low-lying volcanic plains of the northern hemisphere, which were resurfaced by lava flows billions of years ago.
Cevabı ve açıklamayı göster

Cevap

A dash (or em dash)
The sentence contains a nonessential parenthetical appositive phrase ('a heavily cratered, ancient region that preserves the crustal signatures of the early solar system') that interrupts the main clause between the subject ('highlands') and the verb ('stand'). Standard English conventions require that nonessential elements be set off with matching punctuation: either two commas, two parentheses, or two dashes. Because the closing punctuation of this phrase is an em dash ('system—stand'), the opening punctuation at the blank must also be a matching em dash.

Adım Adım Çözüm

1
Identify the structure of the sentence, noting the nonessential parenthetical phrase 'a heavily cratered, ancient region that preserves the crustal signatures of the early solar system' that interrupts the main clause.
Recognized that the phrase is an appositive setting off nonessential information.
To understand the grammatical role of the text between the subject and the verb.
2
Examine the punctuation mark that closes this nonessential parenthetical phrase.
Found an em dash ('system—stand') at the end of the phrase.
Nonessential elements must be set off by matching punctuation marks on both sides.
3
Apply the rule of parallel punctuation to determine the opening punctuation mark.
Concluded that an em dash must be used to open the phrase because an em dash closes it.
Using mismatched punctuation (such as opening with a comma and closing with a dash) violates the conventions of Standard English.

The high school chemistry lab was fully equipped with modern microscopes and advanced safety gear however, the neighboring biology lab still lacked these essential scientific resources.
Cevabı ve açıklamayı göster

Cevap

The semicolon (;) is the correct punctuation mark.
The semicolon (;) is correct because it separates two independent clauses where the second clause begins with the conjunctive adverb 'however'. Since 'however' is in lowercase, a period cannot be used, and a comma would create a grammatically incorrect comma splice.

Adım Adım Çözüm

1
Identify the structure of the two clauses surrounding the blank.
The clause before the blank ('The high school chemistry lab was fully equipped with modern microscopes and advanced safety gear') and the clause after the blank ('however, the neighboring biology lab still lacked these essential scientific resources') are both independent clauses.
Both clauses can stand alone as complete, grammatically correct sentences.
2
Determine the appropriate punctuation to connect the independent clauses when followed by a transition in lowercase.
Because 'however' is a conjunctive adverb starting the second independent clause and is written in lowercase, it must be preceded by a semicolon.
A semicolon is grammatically required to link two independent clauses without a coordinating conjunction when they are joined by a conjunctive adverb.

The correct option uses a semicolon to join two independent clauses ('Many species of bamboo grow at an astonishingly rapid rate' and 'others take years to reach their full height') without a coordinating conjunction. This conforms to Standard English punctuation rules.

Adım Adım Çözüm

1
Identify the clause boundaries around the blank.
The sentence contains two clauses: 'Many species of bamboo grow at an astonishingly rapid rate' and 'others take years to reach their full height.' Both are independent clauses because they can stand alone as complete sentences.
Determining the grammatical status of the clauses helps identify the correct punctuation rule.
2
Evaluate the punctuation options to connect these two independent clauses.
A semicolon is the correct punctuation to join two closely related independent clauses. A comma alone creates a comma splice, a colon is incorrect because the second clause does not explain or expand on the first, and a semicolon cannot be used if the second clause becomes dependent due to a subordinating conjunction.
Applying the rules of punctuation ensures the sentence conforms to Standard English conventions.

Biologists studying the migrations of the monarch butterfly (*Danaus plexippus*) have long marveled at the insect's navigation systems. These systems—which rely on a 'time-compensated sun compass' that integrates visual cues with circadian rhythms_______ enable the butterflies to travel thousands of miles to their overwintering sites in Mexico.

Which choice completes the text so that it conforms to the conventions of Standard English?

Cevabı ve açıklamayı göster

Cevap: rhythms—

Cevap

rhythms—
The phrase 'which rely on a "time-compensated sun compass" that integrates visual cues with circadian rhythms' functions as a nonessential clause modifying the subject 'systems'. Standard English conventions dictate that nonessential information must be enclosed by matching punctuation marks. Because the clause is introduced by an em-dash after 'systems', it must be closed with a matching em-dash before the main verb 'enable'. The choice ending with an em-dash correctly maintains this punctuation symmetry.

Adım Adım Çözüm

1
Analyze the sentence structure to locate the main subject and verb, and identify any intervening clauses.
The main subject is 'systems' and the main verb is 'enable'. The clause starting with 'which' is a nonessential clause modifying 'systems'.
Identifying the clause boundaries helps determine how it should be punctuated relative to the rest of the sentence.
2
Identify the punctuation mark that opens the nonessential clause.
The clause is opened with an em-dash after the word 'systems'.
Nonessential elements must be set off by matching punctuation marks on both sides (either two commas, two parenthetical curves, or two em-dashes).
3
Select the option that matches the opening punctuation mark and properly closes the nonessential clause before the verb 'enable'.
The option containing a closing em-dash ('rhythms—') successfully completes the punctuation pair.
Using any other punctuation mark or no punctuation mark at all would cause an asymmetry or grammatical error.

1
Examine the clause preceding the first blank.
The clause 'During the Late Bronze Age collapse around 1200 BCE1200\text{ BCE}, several major Eastern Mediterranean civilizations experienced sudden, catastrophic declines' is grammatically independent.

Adım Adım Çözüm

1
Identify the clause structures surrounding the blank.
The clause before the blank ('These vents spew superheated, mineral-rich water directly into the ocean') and the clause after the blank ('strange organisms like giant tube worms use these minerals to generate energy') are both independent clauses.
Each clause contains a subject and a verb and expresses a complete thought, meaning both could stand alone as separate sentences.
2
Determine the appropriate punctuation to join the two independent clauses.
A semicolon is required to link them because there is no coordinating conjunction (such as 'and' or 'but') connecting the two sentences.
Using a comma without a conjunction would result in a comma splice, and leaving them unpunctuated would create a run-on sentence.

Semicolons to link independent clauses
Soru 20Soru →

For decades, planetary scientists have debated the origins of the asteroid belt positioned between Mars and Jupiter. Many astronomers believe that the belt is a collection of fragments from a planet that shattered early in the solar system's history_______ others argue that the rocky debris represents primordial materials that were prevented from coalescing into a single planet due to Jupiter's intense gravitational pull.

Which choice completes the text so that it conforms to the conventions of Standard English?

Cevabı ve açıklamayı göster

Cevap: history; others

Cevap

history; others
The correct option correctly uses a semicolon to separate two independent clauses. The clause preceding the semicolon ('Many astronomers believe...') and the clause following the semicolon ('others argue...') are both grammatically complete and can stand alone as sentences, making a semicolon the appropriate punctuation mark to link them.

Adım Adım Çözüm

1
Analyze the grammatical structure of the clauses before and after the blank.
The clause before the blank ('Many astronomers believe that the belt is a collection of fragments from a planet that shattered early in the solar system's history') and the clause after the blank ('others argue that the rocky debris represents primordial materials that were prevented from coalescing into a single planet due to Jupiter's intense gravitational pull') are both independent clauses.
Identifying clause boundaries is necessary to determine the correct punctuation required to link them.
2
Determine the punctuation mark needed to join two independent clauses without a coordinating conjunction.
A semicolon is appropriate to separate two closely related independent clauses when no coordinating conjunction (such as 'and' or 'but') is present.
This avoids grammatical errors such as run-on sentences and comma splices.
3
Evaluate the choices to find the one that correctly applies a semicolon between the two independent clauses without introducing subordinate conjunctions.
The option containing 'history; others' correctly uses a semicolon to link the independent clauses. The option with 'history; while others' is incorrect because the addition of 'while' makes the second clause dependent, which cannot follow a semicolon in this context.
A semicolon must only connect two independent clauses, not an independent clause and a dependent clause.
