Certain grocery items at the local supermarket are on sale, and all grocery items must be FDA approved.
We can infer that...
1) Most items that are on sale are FDA approved items.
2) Some FDA approved items are on sale.
-------------------------------------
2 is correct. but why is 1 wrong.
with #1:
if all items are FDA approved, should the correct way to re-write one be "All items that are on sale are FDA approved items"? also, if all items are FDA approved, can you not logical conclude that most of those items are FDA approved, or must you say that all of them are?
thanks.
