Question 45

Is picking up groceries one of the things you are supposed to do?

Using "is" correctly completes the sentence, as it agrees with the singular subject "one" and forms a proper question structure.

A) is

This option is correct because it appropriately matches the singular subject "one," making the sentence grammatically correct. The phrase "Is picking up groceries one of the things you are supposed to do?" is a clear and properly structured interrogative sentence.

B) am

This choice is incorrect as "am" is the first-person singular form of the verb "to be." It cannot be used here because the subject of the sentence is "one," which requires a different form of the verb.

C) is it

This option is incorrect because while "is" is the correct verb form, adding "it" alters the meaning and structure of the sentence. The phrase would become unnecessarily complicated and does not maintain the intended focus on "one."

D) are

This choice is incorrect because "are" is the plural form of the verb "to be." Since the subject "one" is singular, "are" does not agree with it and results in a grammatically flawed sentence.

Conclusion

The correct answer "is" ensures grammatical accuracy by aligning with the singular subject "one." All other options fail to provide the necessary agreement in number or introduce unnecessary complexity, which detracts from the clarity of the sentence.
