Difficulty: EasyShifts in Construction

In the late afternoon, the library is quiet and peaceful. Students sit at the large oak tables, and librarians shelved books in the background. The soft hum of the air conditioner provides a soothing backdrop for studying.

Which choice best maintains a consistent grammatical tense throughout the passage?

  1. A
    NO CHANGE
  2. shelveAnswer
  3. C
    had shelved
  4. D
    will have shelved

Answer

shelve
The correct answer is 'shelve' because it is a present tense verb that matches the plural subject 'librarians' and maintains consistency with the other present tense verbs in the passage.

Step-by-Step Solution

1
Identify the tenses of the surrounding verbs in the passage.
The verbs 'is' in the first sentence, 'sit' in the second sentence, and 'provides' in the third sentence are all in the present tense.
This establishes that the passage is written from a present-tense perspective.
2
Analyze the underlined verb and determine if it matches this tense.
The verb 'shelved' is in the past tense, which represents an inconsistent tense shift in this context.
A passage must maintain a consistent tense unless there is a logical reason to shift time frames.
3
Evaluate the choices to find the plural present-tense form that agrees with the subject 'librarians'.
The form 'shelve' is the simple present tense and agrees with the plural subject.
Choosing 'shelve' restores grammatical consistency and parallel verb structure.
