Read the following two passages and choose the correct answer to each of the questions.
Rock and soil samples brought back from the moon by the Apollo astronauts have taught scientists much about the composition of the moon. Moon soil contains small bits of rock and glass and was probably ground from larger rocks when meteors impacted the surface of the moon. Scientists found no trace of animal or plant life in the moon soil. In addition to the moon soil, astronauts gathered two basic types of rocks from the surface of the moon: basalt and breccia. Basalt is a cooled and hardened volcanic lava common to the earth. Since basalt is formed under extremely high temperatures, the presence of this type of rock is an indication that the temperature of the moon was once extremely hot. Breccia, the other kind of rock brought back by the astronauts, was formed during the impact of falling objects on the surface of the moon. This second type of rock consists of small pieces of rock compressed together by the force of impact. Gases such as hydrogen and helium were found in some of the rocks, and scientists believe that these gases were carried to the moon on the streams of gases that are constantly emitted from the sun.
