Building a Space Station, in Which Astronauts Would Live For a Considerable Time GMAT Critical Reasoning

Question- 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 of human capacities to live in spacecraft for an extended time.
The argument makes the assumption that

1. the exploration of Mars will be carried out by people traveling in spacecraft and not by robots alone
2. the capacities of astronauts are typical of those of ordinary human beings
3. no unforeseen medical problems will arise on the first mission to explore Mars
4. a mission to Mars will be the first of many missions that will explore the solar system
5. living in spaceship for an extended time presents insurmountable medical problems

The statement given is:
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 of human capacities to live in spacecraft for an extended time.
The question to ask here is - to explore Mars, we'll need to know about the human limits of living in a spacecraft and building a space station is essential.
Now lets look at our options given-

1. the exploration of Mars will be carried out by people travelling in spacecraft and not by robots alone. - This is Correct
2. the capacities of astronauts are typical of those of ordinary human beings - This is Incorrect because Nowhere do we learn that anything will involve normal humans.
3. no unforeseen medical problems will arise on the first mission to explore mars - This is Incorrect
4. a mission to Mars will be the first of many missions that will explore the solar system - This is Incorrect
5. living in spaceship for an extended time presents insurmountable medical problems - This is Incorrect

Hence the answer is A.
