Test 79, Game 4 - Miscellaneous

There are exactly six computers—P, Q, R, S, T, and U—on a small network. Exactly one of those computers was infected by a virus from outside the network, and that virus was then transmitted between computers on the network. Each computer received the virus exactly once. The following pieces of information concerning the spread of the virus have been established:

No computer transmitted the virus to more than two other computers on the network.

S transmitted the virus to exactly one other computer on the network.

The computer that transmitted the virus to R also transmitted it to S.

Either R or T transmitted the virus to Q.

Either T or U transmitted the virus to P.

There’s a sufficient vs. necessary flaw here. Basically, the argument goes like this: Diving headfirst into an industrial sausage grinder will kill you. Stepping in front of a San Francisco Muni train will also kill you. Jimbo recently died. But Jimbo didn’t step in front of a Muni train, therefore Jimbo must have dived headfirst into an industrial sausage grinder.
