(AFA - 2008) Read the text below and answer questions 01 to 04. The Moon The Moon is the Earths only natural satellite. It is relatively large for a moon, with a diameter of about 5,470 kilometers just over a quarter of the Earth. The Moon takes the same time to rotate on its axis as it takes to orbit the Earth (27.3), and so the same side (the near side) always faces us. However, the amount of the surface we can see the phase of the Moon depends on how much of the near side is in sunlight. The Moon is dry and barren, with no atmosphere or water. It consists mainly of solid rock, although its core may contain molten rock or iron. The surface is dusty, with highlands covered in craters caused by meteorite impacts, and lowlands in which large craters have been filled by solidified lava to form dark areas called maria or seas. Maria occur mainly on the near side, which has a thinner crust than the far side. Many of the craters are rimmed by mountain ranges that form the crater walls and can be thousands of meters high. Visual Encyclopedia Mark the option that is contextually and grammatically correct according to the use of adverbs.
