Question 86. A spaceship is on its way to the Moon. While on a space walk outside the spaceship, an astronaut claps her hands together. Which of the following best explains why the astronaut hears no sound?
(a) There is no matter in space in which sound can be transmitted.
(b) The frequency of sound waves produced in space are too high to be heard by the human ear.
(c) Without Earth’s magnetic field, sound waves cannot be transmitted.
(d) The solar wind interferes destructively with sound waves, canceling them out.
