<p>（Prior to） the election of Henry Cisneros (as mayor )of San Antonion in 1981,no major city in the United States (had had) a mayor (from Mexican descent.)
THe answer is D,can anyone explain why?</p>
<p>of mexican descent. Though that (had had) part is freaking confusing.</p>
<p>is ‘of descent’ an idiom？Can I say a mayor who was from Mexican descent?</p>
<p>Idiom. 10 characters</p>
<p>
No. It is “of … descent.”</p>
<p>“Of Mexican Descent”</p>
Well The idiom should be “of XX descent”. But btw, I dont think the had had is confusing. I use “had had dinner” often,(not had eaten dinner although they mean the same thing).
Are you sure the answer is D?
“had had” is fine–it’s the superpast of the verb “had,” as in: By the time Nigel finished his meal, he had had plenty of time to consider Lucretia’s job offer."
The above posters are correct: it’s an idiom error, and the correct collocation is “of Mexican descent.”
