<p>In 1972, (while) (serving as) a congressional representative (from New York), Shirley Chrisholm became the first African American women (to endeavor) the presidential nomination.</p>
<p>(To endeavor) is wrong. WHY???</p>
<p>It’s not a tense error. It’s the wrong verb context. You can’t use “endeavor” in this sentence. You don’t endeavor a presidential nomination. You endeavor to make a presidential nomination succeed.</p>
<p>Substitute “attempt” or “try” for the word “endeavor” in the sentence. Does the sentence make sense?</p>
<p>“to endeavor to win the presidential nomination.” would be the correct way to state phrase.</p>
<p>Is this coming from an official College Board test? I was under the impression that CB rarely tests for correct word choice. </p>
<p>In any case, the sentence should read “to run for” instead of “to endeavor”. (Also women should be woman)</p>
<p>Neither “attempt” nor “try” are good alternatives.</p>
