Question

The teacher ____ pointing to the board. a. was c. were b. has

Answer 1

The correct answer is "was."

The sentence "The teacher ___ pointing to the board" is in the past tense, indicating that the action of pointing to the board happened in the past. Therefore, the verb "to be" should be conjugated in the past tense, which is "was" for the singular form.

The other options are incorrect: - "were" is used for plural subjects, but "the teacher" is a singular subject. - "has" is used for present perfect tense, which implies that the action of pointing to the board happened at some point in the past and is still relevant to the present. However, the sentence is in the past tense, so "has" is not appropriate. - "c" is not a valid option.
