Passage

This passage was adapted from articles published in

The success that Nigerian-born computer scientist Philip Emeagwali (b. 1954) has had in designing computers that solve real-world problems has been fueled by his willingness to reach beyond established paradigms and draw inspiration for his designs from nature. In the 1980s, Emeagwali achieved breakthroughs in the design of parallel computer systems. Whereas supercomputers worked sequentially, they were too slow and inefficient to accurately predict such extremely complex movements.

To model oil field flow using a computer requires the simulation of the distribution of the oil at tens of thousands of locations throughout the field. At each location, hundreds of simultaneous calculations must be made at regular time intervals relating to such variables as temperature, direction of oil flow, viscosity, and gather and broadcast the largest quantity of messages to its processing points in the shortest time.

In 1996 Emeagwali had another breakthrough when he presented the design for a massively parallel computer that he claims will be powerful enough to predict global weather patterns a century in advance. The computer’s design is based on the geometry of bees’ honeycombs, which use an extremely efficient three-dimensional spacing. Emeagwali believes understand the systems evolved by nature and, thereby, to facilitate the evolution of human technology.

Answer choices

  1. Too Strong: obsolete3% picked this

    Emeagwali's breakthroughs in computer design have begun to make computers that

    While Emeagwali's breakthroughs in computer design have allowed him to tackle some really complex problems that sequential computers can't handle, the passage is not saying that sequential computers are becoming obsolete. You're reading this explanation on a sequential computer; and I'm typing this explanation on one too. :)

  2. Too Strong2% picked this

    Emeagwali's first breakthrough in computer design came in response to a request by

    Too Strong: first Out of Scope: requested by oil company We know that Emeagwali had a breaktrhough in computer design that related to modeling oil flow. But we don't know if it was his first breakthrough, and we have no idea whether any oil company ever requested that he work on it.

  3. Correct86% picked this

    Emeagwali was the first to use a massively parallel computer to predict the flow of

    Why this is right

    We would be very scared of the word "first", but we are told in the 1st paragraph that Emeagwali "pioneered the use of massively parallel computers to solve one of the most tricky problems: predicting the flow of oil in oil fields." Whoever pioneered the use of massively parallel computers to solve this unsolvable problem must be the first to do so.

  4. Too Strong: first3% picked this

    Emeagwali was the first computer scientist to use nature as a model

    While Emeagwali does use nature as a model for some of his parallel computer design, the passage never indicates that he was the first computer scientist to ever use nature as a model for human technology. The only language in the passage supporting Emeagwali being the first to do something is when the 1st paragraph says that he pioneered the use of massively parallel computers.

  5. Too Strong: first7% picked this

    Emeagwali was the first to apply parallel processing to solving

    This is another answer stressing that Emeagwali was the first person to ever do something. The only line reference in the passage that clarifies that he was the first is when we're told that he pioneered the use of massively parallel computers to predict the flow of oil. While we know he was the first to apply massively parallel processing to solve the specific real-world problem of oil flow, we don't know if he was the first person ever to apply parallel processing to a real-world problem.
