Here are the arguments categorized correctly:
-
Sound:
- None of the provided arguments qualify as sound.
-
Valid but unsound:
- The argument about John Adams and John Quincy Adams. The conclusion is valid based on the structure of the argument, but the premise (that family members belong to the same political party) is not necessarily true, making the argument unsound.
-
Invalid:
- The argument about the nineteenth amendment and voting patterns. The conclusion does not logically follow from the premises, as greater voter turnout does not imply that the amendment was ratified before 1980.
So the arrangement is:
- Valid but unsound: John Adams and John Quincy Adams
- Invalid: The nineteenth amendment argument
