The sentence above contains a list .

1. can understand English and other human languages,
2. recognize objects,
3. and reason as an expert does

If u see the structure of the elements it is a verb and a noun.
But the third element is not parallel with others.

It should be changed to reflect the other elements.

and reason + a noun will make the third element parallel and "like" is used for noun comparisons

I hope that clarifies.
