LSAT 112 | Section 2 | Reading Comprehension: Q20

RC Question 20 Explanation

DISCUSSION: A second question on the same topic. They’re trying to take it easy on us. Vasopressin keeps water in the kidneys (lines 41-42). So holding back vasopressin gets rid of water. This means that other body fluids such as blood are less diluted.

The correct answer is tricky, because it’s worded indirectly. C is also tricky. It describes what happens when we do have vasopressin.

___________

1. Nope. There’s only one thing said about vasopressin: it keeps water in the kidneys. 
2. CORRECT. Dilution is a reduction in concentration levels. If a body fluid (like blood) has been diluted, that means it has more water. Blocking vasopressin gets rid of water, and this means body fluids are less diluted by water. See lines 41-42. 
3. This is what happens when we have vasopressin. This is the opposite of what happens when we withhold vasopressin.
4. This is never mentioned. 
5. Steroid hormones are never mentioned along with vasopressin. Vasopressin is a peptide hormone.
