1. Fill in the gap: The old castle fire in 1997. a) Was destroy by b) Was destroyed by 6) Was destroyed d) Destroyed e) Was destroy

The correct answer is option c) Was destroyed.

Explanation:

The verb "to be" in past tense is used in the sentence, which indicates that the action occurred in the past. The verb "destroy" needs to be in the past participle form to match the tense of the sentence. The past participle form of "destroy" is "destroyed."

Using the correct form of the verb in the past tense (past participle) is important for grammatical accuracy and clarity of communication. In this case, "was destroyed" is the correct form because the castle was the object being acted upon.

The other options are incorrect:
a) "Was destroy" is incorrect because it does not match the past tense and lacks the correct form of the verb.
b) "Was destroyed by" is incorrect because it lacks the appropriate verb form.
d) "Destroyed" is incorrect because it does not match the past tense form of the verb "to be" used in the sentence.
e) "Was destroy" is incorrect because it does not match the past tense and lacks the correct form of the verb.

To summarize, the correct answer is c) Was destroyed because it matches the past tense form of the verb "to be" and the past participle form of the verb "destroy".
