Мы нашли муравьёв в корзине для пикника.

English Translation

We found ants in the picnic basket.

Here’s another instance where the cloze is correct (муравьёв) but the pronunciation is not (муравье́в). I would expect муравье́в to be pronounced (more or less) like “muravYEV” while the actual pronunciation is more like “muravYOV”.
