Prep 3. Section 1. Question 23 and 24

For question 23, how does (A) violate the rules? For question 24, how does (E) violate the rules? I seem to be missing an important deduction in this question, but somehow I cannot see it.

Thank you for your help!

Re: Prep 3. Section 1. Question 23 and 24

In combination, the third, fifth, and sixth rules dictate that D must fly with at least one of B and C.

#23 (A) With A, B, and C in plane 1, and D in either plane 2 or plane 3 (sixth rule), this breaks the third rule.

#24 (E) Since D cannot fly in plane 4 (sixth rule), this breaks the third rule.

---> This is my problem: the rules never say that A,B,and C can only fly once. So, even with A,B,C in plane 1, D can still fly with B and/or C.

#24 (E) Since D cannot fly in plane 4 (sixth rule), this breaks the third rule.
---> (E) is still right b/c 3 pilots: A,B,C and 2 co-pilots: E and F.

Need help!! Can anyone share their insights?

Re: Prep 3. Section 1. Question 23 and 24

The first and second rules stipulate that all six "are" aboard planes. Therefore, if all three pilots are aboard one plane, D breaks the third rule. Whether or not any of them can and/or will fly more than once is irrelevant. The scope of the game is limited (by rules one and two) to all six flying concurrently.
