Everyone in Biba's neighborhood is permitted to swim at Barton Pool at some time during each day that it is open.

Given

Everyone in Biba's neighborhood is permitted to swim at Barton Pool at some time during each day that it is open.

No children under the age of 6 are permitted to swim at Barton Pool between noon and 5 P.M.

From 5 P.M. until closing, Barton Pool is reserved for adults only.

Evaluate

There was a little bit of cognitive dissonance when we go from reading that everyone is permitted to swim at the pool at some time each day, into reading

When do the little kiddos get to swim? Everything from noon to close is shut off from them:

no children adults under 6 only I I ● noon 5 P.M. close

Goal

It seems like maybe the answer is going to test the hidden idea that "kids under 6 can only swim before noon"?

Let's look for whatever answer we can prove.

5.

If all the sentences above are true, then which one of the following must be true?

  1. Few children under the age

    Too Strong (few children)

    Obviously the rules of this pool aren't too kind to kids under 6 (no swimming for them from noon - close), but we can't extrapolate from pool rules how many kids live in the neighborhood.

  2. Correct

    If Biba's next-door neighbor has

    Why this is right

    Since everyone in BIba’s neighborhood is permitted to swim at Barton Pool and no one under the age of 6 is permitted to swim between noon and when the pool closes, if Biba’s neighbor is under the age of 6, the pool must be open before noon. Biba's no children adults neighbor ↴ under 6 only I I ● noon 5 P.M. close

    Skill tested: Must be True · how this choice captures the argument's function is the move to repeat next time.

  3. If most children who swim

    Unsupported Comparison

    The statements only provide information about the age of the swimmers at different times of the day. It says nothing about the number of swimmers at different times of the day.

  4. On days when Barton Pool

    Unsupported Relationship

    The statements only provide information about the allowed age of the swimmers at different times of the day. It says nothing about the number of swimmers at different times of the day. Just because kids 6 and up are allowed to swim in the noon - 5pm window doesn't mean there definitely are at least some children each day the pool is open.
