TOEIC Reading 5 Exercisee 254

<p>Let's analyze the sentence:<br></p><p><strong>The computer systems (____ are affordable for a Fortune 500 company) will not be affordable for a small company.</strong></p><p dir="ltr"><span><span>The subject is “The computer systems”. The adjective clause is “________ are affordable for a Fortune 500 company” modifies the antecedent “The computer systems.”&nbsp;</span></span></p><p><span>Let’s look at the adjective clause “________ are affordable for a Fortune 500 company.”&nbsp;</span></p><p><span>The blank should be filled with a relative pronoun, and the relative pronoun should be the subject of the adjective clause. Since the computer systems are things, the relative pronoun can be "that" or "which".&nbsp;</span><span>Of all the four choices, only choice (D) is</span><span>&nbsp;the correct answer.</span></p><p><span>(A)</span><span>&nbsp;"in which"</span><span> is incorrect because the relative pronoun “which” is preceded by a preposition “in”, which suggests that this relative pronoun “which” is not used as a subject relative pronoun in an adjective clause.&nbsp;&nbsp;</span></p><p><span>(B)</span><span>&nbsp;"in that"</span><span> is incorrect because “in that” is a phrase used after a statement to explain in what way the statement is true, not used as a subject relative pronoun in an adjective clause.&nbsp;</span></p><p><span>(C) "</span><span>what"</span><span> can be used as a compound relative pronoun which equals&nbsp; “anything that”, with “anything” serving as the antecedent of an adjective clause and “that” as a relative pronoun in an adjective clause. In other words, “what” can’t be used as a relative pronoun alone.&nbsp;</span><br></p>
