Here was the question (taken from a book I read):

Anything wrong here? "The deer carcass's stomach sack bulged out."

Yes 46 (65%)
No 24 (34%)

Congrats to 65% of you.

A sack is a bag such as what Santa carries.
A sac is a "baglike structure in an animal, plant or fungus, as one containing fluid" (dictionary.com).

Perhaps you thought "carcass's" was incorrect, but when you make a singular noun possessive, you add an apostrophe plus an "s"--even if the singular noun ends in "s."
