From the words or group of words lettered A to D, choose the one that best completes the sentence.
The president's speech ... at 7pm yesterday
Answer Details
The best option that completes the sentence is "was broadcast."
The sentence is in the past tense, and the word "yesterday" in the sentence indicates that the action took place in the past. The verb tense that matches with the past tense is the past simple tense. Therefore, the most appropriate option that matches with the past simple tense is "was broadcast."
Option A, "is broadcast," is in the present tense, which is not appropriate for a past event. Option B, "has been broadcast," is in the present perfect tense, which indicates that the action took place at an unspecified time before now. This tense is not appropriate because the sentence refers to a specific past time, which is yesterday. Option C, "were broadcast," is in the past simple tense, but the verb "were" is not appropriate because "the president's speech" is a singular subject, and "were" is for plural subjects. Therefore, "was broadcast" is the best option that completes the sentence.
In conclusion, the correct sentence should be "The president's speech was broadcast at 7pm yesterday."
