Buses 1, 2, and 3 make one trip each day, and they are the only ones that riders A, B, C, D, E, F, and G take to work.
Neither E nor G takes bus 1 on a day when B does.
G does not take bus 2 on a day when D does.
When A and F take the same bus, it is always bus 3.
C always takes bus 3.
Traveling together to work, B, C, and G could take which of the same buses on a given day?
A. 1 only
B. 2 only
C. 3 only
D. 2 and 3 only
E. 1, 2, and 3
and the answer is...
C. I got the answer because of the last sentence: "C always takes bus 3."
For further clarification, here's what Petersons.com said:
Bus 1: If B, then no E or G
Bus 2: If D, then no G
Bus 3: C always
Bus 3: When A and F take the same bus.
How did you do on this one? Again, I feel like the questions sometimes give too much information to throw us off, but with practice I'm sure we will be able to discern the right information to answer the questions!
