Reading the passage
We've already predicted the main point: Emeagwali advances parallel computing by drawing on nature, with oil-field calculations as the main example. We want that connection between his designs, their natural models, and the problems they address.
Working the answers
- A
We see a successful oil-flow application and a proposed weather application, not an established “wide array” of solved problems. A also leaves out nature as the source of his designs, which is central to the discussion.
- B
The author praises Emeagwali's innovation without accusing earlier scientists of stubborn allegiance to old ideas. Nor are these problems described as easy to solve. B invents a criticism of other scientists.
- C
We learn about his designs, not a documented increase in other people's use of parallel systems. C turns technological breakthroughs into a claim about growing adoption.
- DCorrect
This captures the relationship we predicted. The opening connects his success to inspiration from nature; the tree-based network shows how that approach addresses a problem that sequential supercomputers struggled to solve.
- E
The ending does report his prediction about future scientists. But that forecast is an extension of the account of his work, not the central idea developed through the oil-flow example. E shifts the focus from his designs to their possible future influence.
