LSAT 101 | Section 3 | Logical Reasoning: Q2

LR Question 2 Explanation

QUESTION TEXT: Advertisement: Anyone who thinks moisturizers…

QUESTION TYPE: Flawed Reasoning

CONCLUSION: Your skin needs moisturizer.

REASONING: Soil needs water.

ANALYSIS: When you strip away the marketing-speak, this is a pretty silly argument. Your skin is not made of soil, and it doesn’t depend on rain to get water. Your skin uses water you drink.

___________

1. The ad never said that moisturizer was necessary or sufficient for smooth skin. It only implied that moisturizer could help.
2. This is a causation-correlation error, and it doesn’t happen in this question. The argument never said anything like: drought causes both cracked skin and cracked soil.
3. This is a different error. It’s like if I said: “Now, if we can just all agree that it won’t rain tomorrow, then we’ll have nice weather.”
4. Infusion is clear in this case: rainwater is entering the ground.
5. CORRECT. Most people’s faces are made of skin, not mounds of dry dirt. Dirt needs water, but skin might not need moisturizer. The two things are quite different.
