The question asks, "The passage most strongly suggests that Emeagwali holds which one of the following views?"
We're looking for an answer choice that is something that Emeagwali likely believes.
(A) says, "some natural systems have arrived at efficient solutions to problems that are analogous in significant ways to technical problems faced by computer scientists."
The key portion of the text to look at is the second half of the second paragraph. In this portion of the passage, Emeagwali's exploration of the branching patterns of trees is discussed, and it's mentioned that trees evolved this way to maximize their use of taking up resources. Emeagwali's solution to model oil field flow was inspired by his examination of the trees' branching patterns, which were a natural system that solved a problem. Emeagwali then used this as a basis for a model to solve his parallel oil field modeling problem, so (A) is correct because based on the passage, it's something we have strong support that Emeagwali would agree with.
Does this make sense? Let us know if you have any more questions!
