LR Question 25 Explanation

QUESTION TEXT: It is difficult to grow cacti in a humid climate…

QUESTION TYPE: Must be False

FACTS:

1. Cacti can’t easily grow where it is humid.
2. Orange trees can’t easily grow where it is cold.
3. In most of the country, it is either easy to grow cacti or orange trees.

ANALYSIS: We can deduce that in most of the country (>50%), it is not “both humid and cold.” This is because most of the country is suitable for oranges or cacti, and thus either not cold or not humid (or both).

This also means that at most 49% of the country is “both humid and cold,” where neither cacti nor orange trees are easy to grow.

___________

1. CORRECT. This can’t be true. If half of the country is cold and humid, then it’s not possible for “most” of the country to be not cold and not humid.
2. This could be true. “Hot” doesn’t prevent orange trees or cacti.
3. This could be true. In fact, the whole country could be neither cold nor humid. Then cacti and oranges could grow everywhere.
4. This could be true, as long as oranges could grow in most places. The stimulus only says that in most parts of the country it is easy to “grow cacti or … raise orange trees.” It’s counterintuitive, but we only need one of those to be true for the whole statement to be true.
5. This could be true, as long as enough of the country is not cold and not humid such that either oranges or cacti can grow.
