LSAT 112 | Section 3 | Logical Reasoning: Q10

LR Question 10 Explanation

QUESTION TEXT: Jennifer’s comment is related to Peter’s argument…

QUESTION TYPE: Relationship Between Arguments

ARGUMENTS: Peter argues that farmers should give plants just enough water and no more. Otherwise insects will feed on their leaves.

Jennifer adds that a plant with little water will also produce pesticidal toxins and further reduce the amount of insects that want to eat it.

ANALYSIS: Jennifer supports Peter by adding completely new information. Her information doesn’t have anything to do with Peter’s reasoning. It adds new information that supports the conclusion by another method.

___________

1. Not quite. Jennifer’s information doesn’t have anything to do with the idea that plant leaves will become tougher in texture.
2. Nope. Peter’s argument is fine on its own. Jennifer’s argument does support Peter, but by providing a completely new reason.
3. Jennifer introduces a new premise that has nothing to do with Peter’s.
4. Jennifer’s info supports Peter’s conclusion, but has no effect on the premises.
5. CORRECT. If plants produce pesticides when they don’t have too much water than we shouldn’t give them too much water. This has nothing to do with leaf texture – it’s independent from Peter’s reasoning.
