A. Why is the following not a valid deduction? Insects have six legs. The banquet table has six legs. The banquet table is an insect. B. Rewrite the specific statements so that the deduction is valid.

I think it's not valid because it doesn't say everything with six legs is an insect. As it is, the banquet table and insects just share a common trait. So, I would add that "Everything with six legs is an insect" before claiming that "the banquet table is an insect".
