LSAT 113 | Section 3 | Logical Reasoning: Q8

LR Question 8 Explanation

QUESTION TEXT: For all species of higher animals, reproduction…

QUESTION TYPE: Must be False

FACTS:

1. All higher animals require eggs to reproduce but not necessarily sperm.
2. Some species are all female.
3. Eggs from a rare species of salamander hatch without fertilization (i.e. no sperm). The salamanders are all female.
4. The disadvantage is that the children have practically the same genetic code as their parents.
5. Species with male and female members have more genetic diversity.

ANALYSIS: Do not look at the answer choices on this sort of question until you’re clear on what the stimulus actually says. It could get confusing. The correct answer has to be something that directly contradicts one of the five facts I listed above.

___________

1. It could be true that other types of salamanders have both males and females.
2. CORRECT. This has to be false. All higher animals need eggs. The first sentence says so. 
3. This could be true. We weren’t told how many species had males.
4. It could be true that some species simply aren’t very adaptive.
5. This could also be true. The stimulus doesn’t tell us much about how children resemble their parents in species with both males and females.
