Invalid arguement

Step-by-step explanation:

You can't say Loretta's hobby isn't stamp collecting if her husband likes to fish. It is illogical. Same deal with Nathan liking to read. Illogical.

The argument is valid.

Step-by-step explanation:

We are told "Loretta's hobby is stamp collecting."

"If her husband likes to fish, then Loretta's hobby is not stamp collecting."

Her hobby is stamp collecting, so her husband does not like to fish.

"If her husband does not like to fish, then Nathan likes to read."

Her husband does not like to fish; therefore, Nathan likes to read.

The argument is valid.
