Which choice completes the text so that it conforms to the conventions of Standard English?
For subject–verb agreement questions, first strip away prepositional phrases (like “of the museum’s new exhibitions”) to find the core subject, then decide if that subject is singular or plural. Match the verb’s number (singular/plural) and tense (present/past) to this subject and the sentence’s time frame, and eliminate any choices that disagree in either number or tense.
Hints
Locate the true subject
Mentally remove the phrase “of the museum’s new exhibitions” and see what word is actually doing the action in the sentence.
Check if the subject is singular or plural
Ask yourself: Does the sentence focus on many exhibitions together, or on each one individually?
Match subject number to verb form
Once you decide if the subject is singular or plural, eliminate any verb choices that do not match that number.
Consider the time frame
Is the sentence talking about a current, general fact, or something that happened only in the past?
Step-by-step Explanation
Identify the subject of the sentence
Ignore the prepositional phrase “of the museum’s new exhibitions” for a moment. The core of the subject is “Each”, which is singular. Phrases starting with of usually do not change the subject’s number.
Decide on singular vs. plural verb
Because “Each” is singular, it must take a singular verb form. Plural verbs (like “are” or “have been” when used with a plural subject) would not agree with a singular subject.
Match the tense to the context
The sentence describes a general, current feature of the museum’s exhibitions (a standing fact), so it should use present tense, not past tense. That rules out past forms like “were” and perfect forms like **“have been.”
Choose the verb that fits both number and tense
We need a singular present-tense verb to agree with the singular subject “Each.” Among the choices, only “is” is singular and present tense, so the correct completion is: “Each of the museum’s new exhibitions is accompanied by an interactive digital tour …”
