The correct answer is: A. flew
The verb “fly” is used to describe the action of an object moving through the air. In this case, the object is a kite. The kite is the subject of the sentence, and the verb “fly” is in the simple past tense. This is because the sentence is about something that happened in the past.
The other options are incorrect because they do not agree with the subject of the sentence. Option B, “did fly,” is in the simple past tense, but it is in the form of a question. Option C, “flying,” is in the present participle tense. Option D, “were flown,” is in the passive voice.
Here is a brief explanation of each option:
- A. flew (simple past tense) is the correct answer because it agrees with the subject of the sentence, which is “kites.”
- B. did fly (simple past tense) is incorrect because it is in the form of a question. The sentence is not a question, so this option does not make sense.
- C. flying (present participle tense) is incorrect because it is not in the simple past tense. The sentence is about something that happened in the past, so this option does not make sense.
- D. were flown (passive voice) is incorrect because it is in the passive voice. The sentence is about something that was done by someone, so this option does not make sense.
