So I had the answer choices narrowed down to A and D. The way I saw D was that since we are trying to prevent environmental problems from arising, but actually using the spacecraft could damage the ozone layer, we are actually creating an environmental problem. How was I supposed to know that A was a preferred answer over D? (I can sort of see it now that I know the right answers - but this is a harder problem in the latter half of the section, so I always try to thoroughly examine each answer choice.) Thank you.
