<p>The museum (is submitting) proposals (to several) foundations (in) the hope (to gain) funds to build a tropical butterfly conservatory. (No error)</p>
<p>The answer is (to gain). But can somebody explain why?</p>
<p>should be "of ganing"</p>
<p>submitting and gain don't agree</p>
<p>submitting --> gaining</p>
<p>No no no, its not cause submitting and gaining disagree. </p>
<p>Idiomatic usage - Always is "in the hope of". </p>
<p>"hope of" - Noun, example
Sarah works hard in the [hope of] winning the valedictorian title.</p>
<p>"hope to" - Verb, example
Sarah hopes to win the valedictorian title</p>
<p>^ pwns it.
submitting has nothing to od with this</p>
