Answer to Question 1

A

Answer to Question 2

Screams, and any sound that we make, are pressure waves traveling through a gas of atoms and molecules. We perceive sound when these waves strike our eardrums and cause them to vibrate. However, it takes many trillions of such particles to move our eardrums noticeably, and in interstellar space, where the gas density is extremely low, there would be too few (if any) collisions with our eardrums for us to hear sound.
