Take another look at the sentence:

When Simone and her husband discovered sixteen jars full of insects in their daughter's room, they decided to get Maria a dog, tolerating one four-legged animal seemed better than having fifty six-legged "pets" in the house.

Tolerating one four-legged animal is the subject for the verb seemed. You hardly ever use a comma to separate a subject from its verb.

Go back to the sentence to try again.
