Reading the passage
Our main-point predictions already help: A recommends sharing the climate calculations, and B promotes parallel computing more broadly. Both explain how a new computing approach can handle a difficult kind of problem.
Working the answers
- A
They do discuss limitations of individual or sequential computers. But those limitations set up the proposed solution; neither discussion is mainly an attack on traditional computing for common tasks.
- BCorrect
The new approach is parallel computing. A applies it to calculation-intensive climate models, while B explains why it suits naturally parallel problems. This captures what both authors are trying to show.
- C
Where are the skeptics? Neither author identifies an audience that doubts the usefulness of desktop computers and sets out to change its mind.
- D
B describes a shift underway, but A doesn't claim that the new approach has already replaced the old one for most large-scale problems. Recommending an approach isn't showing that it now handles a majority of those problems.
- E
The authors aren't merely describing unsolved problems. They explain an approach to solving them.
