Choose the verb that correctly completes the sentence.

The columnists and the editor _______ all of the editorials in the newspaper daily.
A.
reading
B.
reads
C.
am reading
D.
read

The correct verb that completes the sentence is D. read.

D. read

To choose the correct verb that completes the sentence, we need to identify the subject of the sentence. In this case, the subject is "the columnists and the editor."

Since the subject is plural (columnists and editor), we need a verb that agrees with a plural subject. Therefore, the correct verb is "read", which is the past tense form of the verb "read."

So, the correct answer is D. read.
