Cevabı ve açıklamayı göster

Cevap: the research team discovered a collection of clay tablets detailing regional trade agreements.

Cevap

the research team discovered a collection of clay tablets detailing regional trade agreements.
The correct answer is the option starting with 'the research team' because it places the logical subject that performed the action of the introductory modifier ('Having completed a detailed archaeological excavation of the ancient ruins') immediately after the comma, resulting in a grammatically correct sentence.

Adım Adım Çözüm

1
Identify the introductory modifying phrase.
The introductory phrase is 'Having completed a detailed archaeological excavation of the ancient ruins.' This phrase describes an action that requires a logical agent (whoever performed the excavation).
Standard English conventions require that the subject immediately following an introductory modifier must be the noun or pronoun that the modifier logically describes.
2
Determine the logical subject of the modifying phrase.
The research team is the logical agent that would complete an excavation.
An archaeological excavation is performed by people, such as researchers or a research team, rather than tools or the tablets themselves.
3
Select the option that places the logical subject immediately after the modifying phrase.
The option that begins with 'the research team' correctly aligns the modifier with its subject.
Structuring the sentence this way avoids a dangling or misplaced modifier.

Cevabı ve açıklamayı göster

Cevap: archaeologists determined that the clay had been sourced from a local volcanic deposit.

Cevap

archaeologists determined that the clay had been sourced from a local volcanic deposit.
The introductory modifying phrase 'Having analyzed the chemical composition of the glaze...' describes an action. The noun immediately following the comma must be the entity that performed this action. Since archaeologists are the ones who conducted the analysis, the clause must begin with 'archaeologists.' This structure ensures correct subject-modifier agreement.

Adım Adım Çözüm

Adım Adım Çözüm

1
Identify the introductory modifying phrase in the sentence.
The modifying phrase is 'Having explained the photoelectric effect in 1905,' which is a participial phrase.
To ensure correct modifier agreement, the noun or pronoun immediately following the comma must be the logical subject performing the action in the modifying phrase.
2
Determine the logical subject of the modifying phrase.
The person who explained the photoelectric effect in 1905 is Albert Einstein.
Since Einstein is the one who performed the action, the main clause must start with a subject that refers to him (such as 'he' or 'Einstein') rather than an inanimate object or a different person.
3
Fill in the blank with the appropriate subject pronoun or name.
Using 'he' or 'Einstein' establishes a clear and grammatically correct connection, avoiding a dangling modifier.

Cevap: planetary scientists have identified a surprisingly prolonged period of volcanic activity, thereby providing an explanation for the planet's asymmetric topography.

Cevap

planetary scientists have identified a surprisingly prolonged period of volcanic activity, thereby providing an explanation for the planet's asymmetric topography.
The introductory modifying phrase 'Using a newly developed numerical simulation to model the thermal evolution of early Martian crustal reservoirs' describes an action. The noun immediately following the comma must be the logical actor performing this action. Since planetary scientists are the ones using the simulation, the main clause must begin with 'planetary scientists'. The correct option properly establishes this relationship, ensuring subject-modifier agreement.

Adım Adım Çözüm

1
Identify the introductory modifying phrase and its logical subject.
The modifying phrase is 'Using a newly developed numerical simulation...', and the logical actor performing this action must be 'planetary scientists'.
An introductory participial phrase must modify the subject of the main clause.
2
Evaluate the subject of the main clause in each choice.
Only the option beginning with 'planetary scientists' provides the correct logical subject immediately following the comma.
Placing any other noun (like 'the simulation', 'a surprisingly prolonged period', or 'the identification') as the subject creates a dangling or misplaced modifier error.

Long considered a mere byproduct of cellular respiration, to play a critical signaling role in pathways regulating cell survival.
Cevabı ve açıklamayı göster

Cevap

reactive oxygen species (ROS) are now known
The introductory modifier 'Long considered a mere byproduct of cellular respiration' describes a substance or entity that is produced during respiration. Logically, this describes 'reactive oxygen species (ROS)'. To avoid a dangling modifier, the noun phrase 'reactive oxygen species (ROS)' must serve as the subject of the main clause and immediately follow the comma. The phrase 'reactive oxygen species (ROS) are now known' satisfies this requirement.

Adım Adım Çözüm

1
Identify the introductory modifying phrase and determine its logical target.
The phrase is 'Long considered a mere byproduct of cellular respiration'. The entity that was historically considered a byproduct of respiration is 'reactive oxygen species (ROS)'.
An introductory modifying phrase must logically describe the subject of the main clause that immediately follows it.
2
Evaluate the proposed options to identify which one places the logical target as the subject of the main clause.
The phrase 'reactive oxygen species (ROS) are now known' begins with the logical target, whereas 'scientists now know...' begins with 'scientists' as the subject.
Placing 'scientists' immediately after the comma incorrectly implies that the scientists themselves were considered a byproduct of cellular respiration, creating a dangling modifier.
