Verbs - To Be

The correct answer is "am" because the subject "I" is first person singular and requires the corresponding form of the verb "to be," which is "am."

The correct answer is "is" because it agrees with the subject "My friend" in the present tense.

The correct answer is "were." This is because the sentence is referring to a past event, and "were" is the past tense form of the verb "to be" when used with the pronoun "you."

The correct answer is "is" because "Sam" is a singular noun, and when referring to a singular subject, we use the verb "is" in the present tense.

The correct answer is "are" because "flowers" is a plural noun and requires a plural verb to agree with it.

The correct answer is "is" because "zoo" is a singular noun and requires a singular verb. "Is" is the correct form of the verb to be for singular subjects in the present tense.

The correct answer is "are" because the subject "many wild animals" is plural, so it requires the plural form of the verb "to be" which is "are".

The correct answer is "was" because it agrees with the subject "class," which is a singular noun.

The correct answer is "were" because the subject "my friends" is plural, indicating that there is more than one friend. In English, when the subject is plural, the verb form used is also plural. Therefore, "were" is the correct verb form to agree with the plural subject "my friends."

The correct answer is "was" because it agrees with the subject "my mother" in the past tense. "Am" is incorrect because it is first person singular and does not match the subject. "Were" is incorrect because it is plural and does not agree with the singular subject.
