Use the verb in the correct form: I don’t understand this sentence. What _____ (thisword/mean)?

The correct answer is: B. does this word mean

The verb “mean” is conjugated as follows:

• I mean
• You mean
• He/She/It means
• We mean
• You mean
• They mean

In the sentence “I don’t understand this sentence. What does this word mean?”, the subject is “I” and the verb is “means”. The verb is conjugated in the third person singular because the subject is “this word”.

The other options are incorrect because they are not conjugated in the third person singular.
