Which of the following sentences correctly avoids a dangling modifier?

Show answer & explanation

Answer: After analyzing the network diagnostic reports, the chief technician upgraded the core routers.

Answer

The sentence 'After analyzing the network diagnostic reports, the chief technician upgraded the core routers.' correctly avoids a dangling modifier.
The introductory participial phrase 'After analyzing the network diagnostic reports' describes an action performed by an individual. Placing 'the chief technician' directly after the comma establishes a clear and grammatically correct connection between the modifier and its logical subject.

Step-by-Step Solution

1
Identify the introductory modifier in the sentence
The phrase 'After analyzing the network diagnostic reports' is a participial modifier requiring an agent capable of performing the action of analyzing.
Participial modifiers must modify the noun phrase that directly follows them.
2
Evaluate the main clause subjects in each option
In the correct sentence, 'the chief technician' is the immediate subject following the comma, which logically pairs with 'analyzing'.
An inanimate object like 'the core routers' or an abstract concept like 'the upgrade' cannot perform the action of analyzing reports.
3
Verify modifier agreement and vocabulary correctness
The proper adverbial modification and accurate word choices are maintained without grammatical errors or homophone confusions.
Ensures the chosen option satisfies all syntactic and lexical constraints.

Question 902Question →

During the administrative audit, the executive director was fully exonerated _____ all allegations of financial misconduct because his actions were in strict compliance _____ established ministry guidelines. Which pair of prepositions correctly completes the sentence?

Show answer & explanation

Answer: from / with

Answer

The combination containing 'from / with' is correct because the verb 'exonerate' requires the preposition 'from' when referring to freeing an individual from blame, and the noun 'compliance' forms the fixed idiomatic phrase 'in compliance with'.
The correct response features 'from' paired with 'exonerated' and 'with' paired with 'compliance'. Both prepositions fulfill standard grammatical dependencies in formal English register.

Step-by-Step Solution

1
Determine the dependent preposition governed by the verb 'exonerated'.
The verb 'exonerate' takes 'from' (e.g., exonerated from blame/allegations).
In standard English grammar, one is acquitted of a crime but exonerated from a charge.
2
Identify the correct preposition completing the phrase 'in compliance _____'.
The correct preposition is 'with'.
'In compliance with' is a standard multi-word prepositional phrase meaning in agreement or accordance with a directive.
