Because its using SOME and MOST, we cant say for sure that any one product is exported to Brazil.

For all we know, nuts as a whole are apart of the few products NOT exported to Brazil. Or maybe its everything but almonds.

Only if the stim said ALL products from Cali are exported, can we safely assume that SOME almonds are exported to Brazil.

@KikeHernándezLuvr You know, Mr. Fat cat predicted all this

When you ask yourself which statement is the statement the author wants you to believe, it becomes tough to distinguish whether or not the answer is A or D. However, I think the factors that make the answer obviously A is that its serves as a statement that offers no support for anything in the stimulus. Whereas D is placed as a support that serves A. If you place the two next to each other, you can see which one serves which as a support or conclusion. Same goes for C.
