Read the passage carefully, then choose the correct answer.
There is one planet that still fascinates and teases scientists mainly because it doesn't have an atmosphere to obscure observation, yet it is not big enough for sufficiently accurate telescopic observation. The fact that it is also very close to the sun also makes it difficult for astronomers.
However, space telescopes have told us a lot more about Mercury. It is rather similar to Earth's moon and to Mars. There are mountainous areas dotted with craters and large valleys which are uncratered. The moon's valleys have fewer cracks and the ridges are smoother. Mercury's valleys are filled with volcanic rocks, similar to on the moon, yet there is no evidence of volcanoes, even extinct ones, on Mercury, as there is on the both Mars and the moon, and of course here on Earth.
So, scientists presume the valleys on Mercury were caused by different things, that is to say not by volcanoes, but by very large meteorites, which also caused the cracks in the terrain and left the ridges rough and uneven. More and better photos of Mercury are needed to prove what are at present at best only hypotheses.
What does the author imply space telescopes can do better than land-based telescopes?
A.Show the volcanoes on Mercury.
B.Show the meteorites which hit Mercury.
C.Show what caused Mercury's valleys.
D.Show more of the planet, Mercury.

These markings looked like canals. This finding led astronomers to believe that since water exists on Mars, life forms could exist as well.
However, there are (39) _____ who feel that life on mars is not possible. This is because there is little or no trace of oxygen on the planet. In 1965, the Mariner IV capsule managed to take photographs of the planet. It discovered that the only forms of life found are vegetation like fungi and mosses.
