Stimulus Summary
The stimulus gives us three separate facts. Let's read them one at a time and push them together to make inferences, if possible.
Fact 1: Humid climate → difficult to grow cacti.
Fact 2: Cold climate → difficult to raise orange trees.
Fact 3: In most of a certain country, it's either easy to grow cacti or easy to raise orange trees.
The first two facts create contrapositives that matter for Fact 3. If it's easy to grow cacti somewhere, that place can't be humid. If it's easy to raise orange trees somewhere, that place can't be cold. And notice what "or" means in Fact 3: in most of the country, at least one of these plants is easy to grow. If one isn't easy in a given region, the other one has to be.
So Fact 3 is really telling us: in most of the country, it's either not humid or not cold (or both).
Anticipation
We need the answer that must be false — the one that contradicts what the stimulus guarantees. We just inferred that in most of the country, it's either not humid or not cold (or both). The correct answer is likely to contradict this inference.
