Let me clear the confusion for some:

"Choose your answer based solely on the information given in the FIRST THREE facts".

So just because the 3rd statement/question says "All red drink mixes are drinkable".

Doesn't make it a FACT from which you can base your decision.

Drink mixes = beverages.
Beverages = drinkable.
Some beverages = red.

I) some drink mixes are red:

Ok, we know that all drink mixes are beverages but it is not explained that all beverages are drink mixes so this answer is not a known fact.

II) All beverages are drink mixes:

It is the same explanation than upper. We know that all drink mixes are beverages but it is not explained that all beverages are drink mixes so this answer is not a known fact.

III) All red drink mixes are drinkable:

For this one, we need to make the deduction. Indeed, we know that all drink mixes are beverages and that some beverages are red so some drink mixes are red and as all beverages = drink mixes = drinkable Finally all red drink mixes are drinkable which is a known fact.

Here, Concl 1 & 3 both are Correct.
1, Since all Drink mixes are Beverages then some red will be Drink mixes.
3. Since all Bev are drinkable then automatically some Red which is said to be Bev are drinkable!!
