LR Question 13 Explanation, by LSATHacks

QUESTION TEXT: Mature white pines intercept almost all the sunlight…

QUESTION TYPE: Complete the Argument

ARGUMENT: Mature white pines don’t let any light through to the forest floor. Trees can’t grow beneath them once they mature.

ANALYSIS: This was a difficult question to pre-phrase. It’s simplest to know the premise well (trees can’t grow beneath mature pines), and pick the answer that has to be true based on that.

___________

1. CORRECT. Because new mature white pines can’t grow once the trees above them reach maturity.
2. Hard to say. There could have been other trees that let light through and allowed the pines to grow.
3. We don’t know. All the mature pines might receive light just fine. They’ll all survive. It’s new trees that can’t grow.
4. We have evidence this won’t happen. There’s no light on the forest floor!
5. Hard to say. Some trees in certain sections of the forest could have grown faster due to better conditions in that area.

Recap: The question begins with “Mature white pines intercept almost all the sunlight”. It is a Complete the Argument question. Learn how to master LSAT Complete the Argument questions on the LSAT Logical Reasoning question types page.
