Consider the following statements in respect of a jet engine and a rocket :
1. A jet engine uses the surrounding air for its oxygen supply and so is unsuitable for motion in space.
2. A rocket carries its own supply of oxygen in the gas form, and fuel.

{'jet engine': [0, 0, 1, 1], 'oxygen supply': [0, 0, 2, 1], 'rocket': [0, 0, 1, 4], 'gas form': [0, 0, 1, 0], 'oxygen': [3, 0, 1, 0], 'fuel': [1, 0, 5, 14], 'air': [1, 0, 0, 0], 'space': [4, 1, 7, 12], 'motion': [0, 0, 0, 3]}

The correct answer is option 3, which suggests that both statements are correct.

Statement 1: A jet engine does indeed use the surrounding air for its oxygen supply, which is critical for ignition and fuel burn. Because there is no surrounding air (and hence no oxygen) in space, jet engines wouldn`t work there.

Statement 2: A rocket carries its own supply of oxygen along with fuel, which is correct. The oxygen isn`t necessarily in gas form, it might also be in the form of a liquid or even a solid oxidizer depending upon the type of the rocket engine. This design makes it possible for rockets to work independently of the ambient atmosphere, making them suitable for space travel.

In conclusion, both statements provide an accurate understanding of the workings of jet engines and rockets, which is why option 3 is the correct answer.
