premise: How to determine the sex of a cat<br>Approach the cat or kitten with care. To ascertain the sex of a cat or kitten, it's necessary to pick the cat up. Some cats don't like to be handled, so take a little time to let him or her get comfortable around you.
hypothesis: If you pick up a cat you will know what gender it is.
reason: Just picking up a cat does not mean you will necessarily know what sex it is.  You have to also hold it upside down and look.  The system might have been confused by my use of the word "gender"
