<p dir="ltr" style="text-align: justify;"><span><span style="">This question is a simple sentence that fits the pattern: S + V + SC. The subject is “________ interns,” the verb is “is,” and the subject complement is “a sensible solution to filling entry-level positions eventually at Royal Bank.”</span></span></p><p><span style="text-align: justify;">Both a gerund and a to-infinitive of a verb can serve as a subject in a sentence. Thus, (C) "</span><span style="text-align: justify;">Recruiting"</span><span style="text-align: justify;"> is the correct answer. (D) "</span><span style="text-align: justify;">To recruiting"</span><span style="text-align: justify;"> is incorrect unless it’s rewritten into “To recruit.”. (A) "</span><span style="text-align: justify;">Recruits"</span><span style="text-align: justify;"> and (B) "</span><span style="text-align: justify;">Recruit"</span><span style="text-align: justify;"> are incorrect because neither of them can serve as the subject of a sentence. </span></p>
