In studying this planet, astronomers have found that life may be possible on Mars. The first (38) _____ of this is that Mars has seasons, just like Earth.

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 9bscure 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.

a. The planet, Mercury 	b. Observation of planets
c. The Earth's moon 	d. Astronomers' difficulties
Why does Mercury still tease scientists?

b. Because it is too close to the sun;

What is true about Mercury but not true about the moon or Mars?
a. The valleys are filled with volcanic rocks. 	b. There are no volcanoes.
c. The valleys are uncratered 	d. There are hilly regions.
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.
What can we infer from the passage that astronomers still need to get more detailed observation of Mercury?
a. Better and more space telescopes 	b. More hypotheses.
c. Larger space telescopes 	 d. More ways to prove hypotheses.
