LSAT 69, Logical Reasoning II, Q5

QUESTION TEXT: Physiologist: The likelihood of developing osteoporosis is…

QUESTION TYPE: Paradox

PARADOX: Dairy has lots of calcium. Calcium prevents osteoporosis. But countries that get calcium only from fruits and vegetables have less osteoporosis.

ANALYSIS: There are a few possibilities. One would be that the form of calcium in fruits and vegetables is easier to absorb.

The other would be that there’s something present in dairy that prevents calcium absorption.

___________

1. This shows that eating too much calcium isn’t bad. Who cares? We need to explain why dairy seems harmful.
2. That’s nice that some people eat dairy. So what? The stimulus considered countries where people don’t eat dairy. We want to explain why they get less osteoporosis.
3. This shows that calcium deficiency doesn’t always lead to osteoporosis. That’s fine. Calcium deficiency just has to increase the risk of getting osteoporosis.
4. This shows that some deficiencies go together. But it doesn’t explain why people have less osteoporosis when they don’t eat dairy.
5. CORRECT. This shows that people who eat dairy don’t absorb all the calcium that’s in dairy.So effectively, you get more calcium from eating fruits and vegetables.
