<span id="docs-internal-guid-c8e08c9f-7fff-49d9-82d0-682b688ddbbd"><p dir="ltr"><span>Let’s focus on the adjective clause, “that _______ by universities throughout the country.” </span></p><p dir="ltr"><span>The word “that” in this adjective clause is a subject relative pronoun that refers to the antecedent “the technology conference,” a singular noun. In other words, the blank should be filled with a singular verb to complete this adjective clause. For this reason, (B) "</span><span>are hosting"</span><span> can be eliminated first since it’s a plural verb. </span></p><p dir="ltr"><span>Next, since the technology conference is held instead of holding another activity, the verb should be a passive verb. Thus, (A) "</span><span>hosted"</span><span> is eliminated because it’s an active verb in the simple past tense. </span></p><p dir="ltr"><span>Only (C) "</span><span>is hosted"</span><span> and (D) "</span><span>was hosted</span><span>"are possible answers. Now, we need to look at the tense. </span></p><p dir="ltr"><span>The phrase “Each year,” and the main verb “send” indicate that the technology is held regularly instead of being held sometime in the past. Therefore, (D) "</span><span>was hosted"</span><span>, a passive verb in the simple past tense, is incorrect. (C) "</span><span>is hosted"</span><span> is the correct answer since it’s in the simple present tense. </span></p></span>
