LR Question 16 Explanation

QUESTION TEXT: A recent study found that small rats were approximately twice …

QUESTION TYPE: Miscellaneous

FACTS:

1. Small rats are 2x as likely to suffer from heart problems as average sized rats.
2. Large rats are 0.5x as likely to suffer from heart problems as average sized rats.

ANALYSIS: This is an EXCEPT question, so 4 answers should help explain the pattern, and one won’t.

The wrong answers will explain why small rats might be more prone to heart problems, or why large rats might be less prone to them.

___________

1. CORRECT. If small rats are dying early from other diseases, that would not explain why they have more heart problems. If anything, it seems to point the other way and makes it more confusing.
2. Smaller blood vessels could make small rats more vulnerable to clogging and therefore heart problems.
3. If large rats live less stressful lives, that could help explain why they have fewer heart problems.
4. This gives a common cause for both being undersized and having weak hearts.
5. More activity could improve cardiovascular health and help explain why large rats have fewer heart problems.
