Reading the passage
What role do the climate trends play? They're the complicated natural system we want to model. So we're looking for the similarly complicated whole in B: the ant colony. Match the roles, rather than choosing an answer just because it mentions computers.
Working the answers
- A
These computers are the means of solving the problem. Climate trends are what we're trying to understand, not the computers doing the work.
- B
This isolates one ant's simple rules. That is closer to a single component of a climate model than to the large-scale trends produced by all the components interacting.
- CCorrect
The behavior of thousands of ants is the complex whole. B says the individual elements, “taken collectively,” function as a highly complex system. That matches the interacting variables that produce the large-scale climate trends in A.
- D
The shift describes a change in how we compute. A climate trend isn't a change in computing methods.
- E
This is a limitation of the tool used to model a system, not the complex natural system being modeled.
