This doesnβt capture the focus on the new paradigm of parallel computing. The purpose isnβt merely to criticize the old paradigm.

This best captures the purpose of both passages, which is to tell us about parallel computing and how it can help solve complex problems. See the last paragraph of Passage A and the last paragraph of Passage B.

This doesnβt capture the purpose, because we have no reason to think the authors wrote their passages for skeptics. We have no reason to think that there even exist any skeptics of the usefulness of desktop computers for heavy-calculation problems.

Neither passage suggests that parallel computing has replaced non-parallel computing for βmostβ (over half) of large-scale problems. Neither passage quantifies the proportion of problems that now are solved using parallel computing.

The primary purpose of each passage is focused on the solution to complex problems. The authors donβt focus on the different kinds of problems; they want to tell us about how we can solve complex problems using parallel computing.
