LSAT 152 | Section 4 | Logical Reasoning: Q7

LR Question 7 Explanation

QUESTION TEXT: Nutritionist: Contrary to popular belief, a high-calcium diet …

QUESTION TYPE: Strengthen – EXCEPT

CONCLUSION: A high-calcium diet does not prevent osteoporosis.

REASONING: Actually, low-protein diets and weight-bearing exercise are associated with better bone density.

ANALYSIS: The argument does two things:

• Calcium is not the key
• Low-protein and heavy lifting ARE the key

Four answers will also do one or both of those two things. We don’t want those answers.

One answer will either attack one or both of those two things, or not impact the argument at all. That’s the one we want.

___________

1. This strengthens by showing that without weight-bearing stress in space, bones weaken.
2. CORRECT. This introduces a completely different way to prevent osteoporosis (medical therapy).
3. This strengthens by showing low protein leads to low osteoporosis.
4. This also strengthens by doing the first point: weakening the calcium theory.
5. This also strengthens by showing low protein leads to low osteoporosis.
