Reading the passage
B should approve of A's proposal. B argues that parallel computing is a good way to handle demanding parallel problems; A proposes exactly that kind of division of work for climate models.
Working the answers
- A
The “live computer” image describes an ant colony. B doesn't use it to describe connected desktop machines.
- B
A says an individual computer is inadequate for the huge task. Connecting many computers is the proposed solution, consistent with B's recommendation.
- C
B emphasizes the capacity gained by having computers work together. It doesn't say A's system would impose strict limits on the number of variables in its simulations.
- D
B never discusses public participation. Its enthusiasm for parallel computing doesn't tell us how popular a particular volunteer project would be.
- ECorrect
B contrasts computers working simultaneously with the “speed limits” of purely sequential computing. A's system divides the calculations among machines working at the same time, so B's reasoning supports this advantage in speed.
