Though the origins of the dog/human partnership remain unknown, it's

less prevalent even in wild dogs than in wolves.
But, Yale's Laurie Santos says, dogs may have compensated in other
interesting ways. They've learned to use humans to solve problems.
"Several researchers have presented dogs and wolves with an impossible
problem (e.g., a puzzle box that can't be opened or a pulling tool that stops
working) and have asked how these different species react," Santos explains.
Researchers have found that wolves try lots of different trial and error tactics to
solve the problem - they get at it physically. But at the first sign of trouble, dogs
do something different. They look back to their human companion for help. This
work hints that dogs may have lost some of their physical problem-solving abilities
in favor of more social strategies, ones that rely on the unique sort of cooperation

ご質問の箇所のみについてご説明をさせていただきます。

it ＝ the problem が正解とあるが
it ＝ solving the problem はどうか？

というご質問でよろしいんですよね？

結論としては、solve を含めてはダメです。

理由は 下線部を含む１文の　they get at it physically の get at の意味にsolving を含めたらダメな理由があります。

英英辞典のロングマンによると get at ＝ to try to explain something, especially something difficult または to discover information, especially the truth about a situation とあります。日本語に直すと「何かを説明しようとすること、特に難しいものを説明しようとすること」または「情報を見つけること、特にある状況における真実を見つけること」とあります。get at の意味に、すでに solve の意味が含まれているから solving the problem はダメなんだと考えるのがわかりやすいと思います。

ちなみに、problem は a difficult situation 「困難な状況」の意味で、 solve は to find a way of dealing with a difficult situation 「困難な状況に対処する方法を見つける」という意味です。

参考になればうれしいです。
