The only physical factor preventing a human journey to Mars has been weight. Carrying enough fuel to propel a conventional spacecraft to Mars and back would make even the lightest craft too heavy to be launched from Earth. A device has recently been invented, however, that allows an otherwise conventional spacecraft to refill the craft’s fuel tanks with fuel manufactured from the Martian atmosphere for the return trip. Therefore, it is possible for people to go to Mars in a spacecraft that carries this device and then return.
Which one of the following is an assumption on which the argument depends?
(A) The amount of fuel needed for a spacecraft to return from Mars is the same as the amount of fuel needed to travel from Earth to Mars.
(B) The fuel manufactured from the Martian atmosphere would not differ in composition from the fuel used to travel to Mars.
(C) The device for manufacturing fuel from the Martian atmosphere would not take up any of the spaceship crew’s living space.
(D) A conventional spacecraft equipped with the device would not be appreciably more expensive to construct than current spacecraft typically are.
(E) The device for manufacturing fuel for the return to Earth weighs less than the tanks of fuel that a conventional spacecraft would otherwise need to carry from Earth for the return trip.

What's the conclsuion - See you can add some of your words in the conclusion too - Weight is the only factor that prevents the human journey but a device is created that will help is filling that fuel at martian atmosphere so now it's possible for humans to travel
See what's the assumption is - So the assumption is weight of the device must be less than the tanks of fuel that a conventional spacecraft would otherwise need to carry
Clearly our answer is E

Can someone put light on E is correct? Since if we consider the device would be taking the use of martian fuel, would not the spacecrafts be sent with only one way of fuel. Since it is not going to be equivalent for the two-trip fuel, the martian fuel required, would anyways be light given that is required only for a single way, making only one point of reasoning what is the composition of the fuel.
