What _________ Add and Helen __________ when you broke the glass?a)are...
Explanation:
The correct answer is option C: were/doing.
In this sentence, we are talking about past events, so we need to use the past tense. The subject of the sentence is "you," which is plural, so we use the plural form of the verb "to be," which is "were."
Subject-Verb Agreement:
- The subject is "you," which is a plural pronoun.
- The verb "to be" in the past tense is "were."
Verb Tense:
- Since the action of breaking the glass has already happened, we need to use the past continuous tense for the verb "to do."
- The past continuous tense is formed by using the past tense of "to be" (were) and the present participle of the main verb (doing).
Applying the Rules:
- When you broke the glass, what were Add and Helen doing?
- The subject "you" is plural, so we use "were" as the past tense of "to be."
- The action of breaking the glass is in the past, so we use the past tense "broke."
- The action of Add and Helen is ongoing in the past, so we use the past continuous tense "were doing."
Correct Answer:
- In summary, the correct answer is option C: were/doing.
