Read the excerpt from Team Moon.

The heavier the spacecraft, the harder it is to launch. And fuel is heavy. So it was critical to pinpoint the fuel needed, add a cushion, then take no more than necessary. But now, because the landing was taking far longer than planned, the fuel was almost gone. Mission Control wanted Neil to take as much time as he needed and fly the LM as near empty as possible only because they wanted him to make the landing. But if he ran out of fuel above the surface, in all likelihood the LM would crash onto the moon. So they were trying to time it to the last possible second before calling an abort—calling off the landing.

Why does the author use a problem-solution text structure in the paragraph?

to help the reader understand how the fuel system on a spacecraft works
to help the reader understand the difficult decisions faced by Mission Control
to help the reader understand the differences between the two astronauts
to help the reader understand how the country’s space program got started

Problem-solution text structer is often used pattern in writing when the author wants to express a problem or a dilemma but also offer a possible solution.

In this excerpt we see a difficult situation. Mission Control needs to find perfect timing for landing. Fuel is heavy and if there is too much of it left, the landing will be unsuccessful. On the other hand, if too much of the fuel is gone then the LM will crash.

This should give an insight on the importance of the decisions made by Mission Control.
