Building a space station, in which astronauts would live for a considerable time, is essential even if the space station project were to contribute no new knowledge about space or Earth that could not otherwise be obtained. For future missions to explore Mars, we will need the medical knowledge that the space station project will give us about the limits human capacities to live in spacecraft for an extended time.

The argument makes the assumption that

(A) the exploration of Mars will be carried out by people travelling in spacecraft and not by robots alone.
(B) the capacities of astronauts are typical of those of ordinary human beings
(C) no unforeseen medical problems will arise on the first mission to explore mars
(D) a mission to Mars will be the first of many missions that will explore the solar system
(E) living in spaceship for an extended time presents insurmountable medical problems

Premise: "For future missions to explore Mars, we will need the medical knowledge that the space station project will give us about the limits human capacities to live in spacecraft for an extended time."

assumption: because humans are needed for space missions to mars

Conclusion: So, "building a space station, in which astronauts would live for a considerable time, is essential"

If choice A is not assumed i.e, if humans are not needed for future missions, then the argument is not true. Therefore choice A.

A is essential to the argument, but so is B. How did you eliminate B? If the capacities of astronauts are NOT typical of those of ordinary human beings, then how can the argument "about the limits human capacities to live in spacecraft " still stand? Thanks in advance!

Option B is not correct. It can not be an assumption, as it has been mentioned in the argument. First line states that: Space stations in which, astronauts will live for a considerable time. The last line states: the space station project will give us about the limits human capacities to live in spacecraft for an extended time. So, it is obvious that astronauts will be human being with same capabilities. An assumption is an unstated fact, for argument to hold true.

Hope that helps.

Between A and B. In my opinion both have potential to be viable assumptions, but were A to be true the entire argument would fall. Let's look at B If astronauts have greater capabilities than those of humans then it is very likely that the medical knowlodge the machines installed at the space station will gather is be tailored and aimed at astronauts' capabilites; If machines were taught to gather and test data relative to ordinary human beings- knowing that astronauts are trained to endure harsher environments- that would result in both a waste of time and a splurge of money.

On the other hand, reversing A future space missions would be carried by robots; bankrolling the space station would be a splurge, since robots are not very likely going to be affected in the same way as humans.

the answer is A. Not easy though.

hope it helps

if we negate A, the argument breaks down.
A is the assumption..the other ones can easily be eliminated.

Since the premise contains the information that spacecraft will be used by astronauts and their stay will provide knowledge about medical limitations of human beings, it is given that their health matches more or less than any ordinary citizen.

Negating A will cause the argument to fall apart since it is assumed that study will provide essential information about humans. A is an assumption on which that conclusion rests, since it assumes that all of the astro will be humans.

The argument is that building a space station is essential because we will need medical knowledge about the limits of human capacities to live in spacecraft. Choice B is:

"the capacities of astronauts are typical of those of ordinary human beings"

It is not essential for this statement to be true, because ordinary human beings will not be living in spacecraft, only astronauts. So we can safely eliminate B

It's true that if we negate A, the argument breaks down.But in the premise it is stated that "For future missions to explore Mars, we will need the medical knowledge that the space station project will give us about the limits human capacities to live in spacecraft for an extended time".Now why would astronauts be tested without a reason.If we break this question in conventional way then A is right answer but the way this question is written,does not make it a good question.
