<p>This liberal arts college (has) decide (requiring) all students (to study) (at least one) non-European language. (No error)</p>
<p>Okay. So, idiom questions get me like, every time. The answer is B but I put C… </p>
<p>Can anyone explain what’s wrong with B? Does “requiring” have to be “to require.”</p>
<p>How can I improve my chances of getting idiomatic expression questions correct? </p>
<p>Thanks in advance!</p>
