Reading the passage
B is broader than A. A focuses on climate models and proposes connecting computers to handle the calculations. B discusses parallel computing generally and explains why it suits complex problems. Let's use that relationship to evaluate the answers.
Working the answers
- A
Saying B has “little bearing” on A is wrong. The two discussions are closely related: B explains the kind of computing that A proposes.
- B
B favors parallel computing. It doesn't explain why A's plan is unlikely to happen.
- CCorrect
B supplies a reason to use A's proposed approach. If a problem has many elements operating in parallel, B says a computing model that reflects that structure will perform best. That helps explain why dividing climate calculations among computers is a sensible solution.
- D
The ant example illustrates how simple elements form a complex system. It doesn't show why reliable climate prediction requires examining every possible combination of variable values. That's a separate point made in A.
- E
Both authors recognize limits on what an individual computer can do and support sharing demanding calculations. B doesn't conflict with A's assumptions about individual machines.
