(C) Canadian <-s-> International

[can_I_ever_reach_a_170?]

I thought about this question over some time, and I'm still lost.
I didn't like any of the answer choices.

Here's my diagram using words:
Shown at the L festival -> only Canadian films
Most films that won at the L festival -> Won at International festivals

I don't really see a connection between Canadian films and International festivals.
Being shown and winning are different to me.
Do I have to assume winning at the festival means it was shown at the festival?
Then, is it correct to say, Most films shown and won at the L festival -> also Won at International festivals? (I'm assuming Most films shown and won at the L festival are all Canadian films. And not every Canadian film shown at the L festival won, or there's at least some Canadian film that was shown but did not win at the L festival.)

Can I actually use this diagram below?
Most films won at the L festival -> Canadian films
Most films won at the L festival -> Won at International festivals
So, we can make a connection with Some between Canadian films and Winning at International festivals.

Please correct my thinking!

I wonder if diagramming is helping you at all on this task. Perhaps it's simpler to think to yourself, "The correct answer to Inference questions (almost) always involves combining 2 or more facts. They've only given me two facts here, so how can I combine them? What overlapping information do they have?"

As you surmised, the overlap is that both sentences talk about films that were shown/won awards at the LN festival.

Yes, we're supposed to assume that if you won a prize at a film festival then that film must have been shown at that festival.

Does that HAVE to be true? Not really, but if we were to argue with this question by saying, "What if you weren't shown at the festival but still won an award?" we'd be guilty of doing what they warn us against at the beginning of every LR section:
"You should not make assumptions that are by commonsense standards implausible, superfluous, or incompatible with the passage."

So the overlapping fact in our two sentences is about the films that where shown and won an award at the festival.

We know
1. they were all Canadian
2. most of them also won prizes at international festivals.

So, yes, as (C) says, we know that at least one film that won a prize at an international festival was Canadian.

If you wanted to diagram this, you'd be using this formula.

All A's are B.
Most A's are C.
--------------------
Thus, some B are C

All [winners at the LN festival] are Canadian.
Most [winners at the LN festival] also won prizes at international festivals.
----------------------------------------
Thus, some Canadian films won prizes at international festivals.

Hope this helps.
