<p dir="ltr"><span><span>This question is a simple sentence following the pattern: S + V + O. The subject is “Graduating employees,” and the blank should be filled with a verb along with the object “the workforce.” </span></span></p><p>The key to identifying the correct answer is to find out the correct verb tense. (B) "is entering the workforce" and (D) "was entering the workforce" should be eliminated since both of them use singular verbs, but the subject is plural. <br></p><p><span><span>Next, based on the meaning of the context, the fact that graduate employees enter the workforce with too few business skills is happening now, not something that was happening in the past. Thus, the correct answer is (A) "</span><span>are entering the workforce"</span><span> (the present continuous tense), not (C) "</span><span>were entering the workforce"</span><span> (the past continuous tense). </span></span></p>
