Answer

Brief Explanations:

  1. For the first argument about nerds and glasses: Just because some nerds don't wear glasses and grandpa wears glasses, it doesn't mean grandpa can't be a nerd. The "some" in the first - premise doesn't exclude the possibility of other nerds wearing glasses.
  2. For the second argument about cows: If all cows eat grass and all animals that eat grass live outdoors, by the law of syllogism, it logically follows that all cows live outdoors.
