LSAT 134 | Section 2 | Logical Reasoning: Q5

LR Question 5 Explanation

QUESTION TEXT: Everyone in Biba’s neighborhood is permitted to swim …

QUESTION TYPE: Must Be True

FACTS:

1. Everyone in Biba’s neighborhood is allowed to swim sometime each day the pool is open.
2. Children under 6 can’t swim from 12PM to 5PM.
3. After 5PM, the pool is adults only.

ANALYSIS: The key here is combining the rules for children under 6 because we know the most about them.

A child under 6 cannot swim:

• 12PM (noon) to 5PM
• after 5PM, because that time is adults only

So if a child under 6 lives in Biba’s neighborhood, that child still has to be allowed to swim at some time during the day. Rule 1 tells us that.

But rules 2 and 3 tell us they can’t swim from 12PM to closing.

So the only time left is before 12PM, i.e. before noon.

That means the pool must be open before noon.

___________

1. We have no idea how many young children live there.
2. CORRECT. That child is part of the neighborhood, so they must be allowed to swim sometime. Since they cannot swim from noon onward, the pool must be open before noon.
3. We know nothing about crowd size.
4. Children under 6 can’t swim from 12-5PM, and after 5PM is adults only. Older children might swim before 5, but we are not told they must. Maybe the children really don’t like swimming.
5. Only children under 6 are banned between noon and 5PM. As far as we know, older children could be allowed before 5 and not break any rules.
