Question

Difficulty: EasySubject-Verb Agreement

Read the sentence and determine the correct present-tense form of the verb "to be" that completes the sentence with proper subject-verb agreement.

Answer:The main ingredient in these classic recipes 【is】 butter, which gives the pastry its flaky texture.

Answer

is
The singular verb "is" correctly agrees with the singular subject "ingredient." The intervening prepositional phrase "in these classic recipes" does not affect the subject's number.

Step-by-Step Solution

1
Identify the simple subject of the sentence.
The subject is the singular noun "ingredient."
The prepositional phrase "in these classic recipes" modifies the subject but does not change its number.
2
Determine the singular present-tense form of the verb "to be" that agrees with the singular subject.
The correct singular form is "is."
A singular subject requires a singular verb ("is").
