Reasonable people adapt themselves to the world; unreasonable people persist in trying to adapt the world to themselves. ██████████ ███ ████████ ███████ ██ ████████████ ███████
Although there's an argument structure here, that's not our focus. We can accept each claim as true, so it doesn't matter if the conclusion is well-supported or not. These are the three claims we're concerned with:
(1) reasonable people adapt themselves to the world;
(2) unreasonable people try to adapt the world to themselves; and
(3) all progress requires unreasonable people.
The correct answer might come from a single claim—for example, based on claim (1), if someone doesn't adapt themselves to the world, they are not reasonable. The correct answer may also come from combining one or more claims—for example, from claims (2) and (3) we can see that people who try to adapt the world to themselves are necessary for progress.
In any case, the correct answer will be logically guaranteed by the stimulus. We should be able to identify the specific claim(s) that make it true. Incorrect answers will go beyond the stimulus in some way or will make assumptions.

The stimulus never discusses the compatibility of reasonable and unreasonable people, so we can't say that (A) must be true. The idea of compatibility is simply beyond the scope of the stimulus.

The stimulus gives unreasonable people as a necessary condition for progress. We can state this as "only if there are unreasonable people will there be progress." (C) switches this for a sufficient condition, which doesn't have to be true. A precondition can be met without guaranteeing the result.

The stimulus only tells us that unreasonable people are necessary for progress. Based on this, it could be true that all unreasonable people can bring about progress, or that only some of them can. Since either option could be true, (D) doesn't have to be true.
