5. All informative things are useful things. Some websites are not useful things. Some websites are not infor­mative. If the first 2 statements are true, then the third statement is: True False Uncertain

1. Uncertain

We don’t have enough information here to make a decision. Perhaps the gold fish can swim faster than the black fish AND the silver fish – we don’t know.

2. True

This argument is a little sloppy, because the 2nd statement and the conclusion both use ‘some.’ However, it is a valid argument.

3. False

This is a clearly false argument.

4. True This is a very strong argument. If the first two statement are true, then the third statement or conclusion must be true.

5. True

This is a strong argument since the first statement uses ‘all,’ and the second statement uses ‘some.’ And the conclusion uses ‘some.’
