In studying this planet, astronomers have found that life may be possible on Mars. The first (24) _____ of this is that Mars has seasons, just like Earth.

Astronomers also think that perhaps a small (26) ______ of water vapor could be found on Mars. In 1887, an Italian astronomer, Giovanni Schiaparelli, discovered markings on Mars' surface. 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 others who feel that life on Mars is not possible. This is because there is little or no trace of oxygen on the planet.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.
Life in the Universe
Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such a life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extraterrestrial life forms might be like.
What sorts of planets are most likely to develop life? Most scientists likely to agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble the continuous movement ands transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important.
The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and burn out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problems. First of all, planets is their habitable zones will be so close to the stars that they will be “tidally blocked”- that is one side of the planet will always face the star in perpetual daylight with the other side in perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem.
Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two.
Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas gains, such as Saturn and Jupiter, in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth
It can be inferred from the paragraph 3 that ______.
A. the Earth is in the sun’s habitable zone
B. the Earth is tidally locked to the sun.
C. the sun varies in its luminosity.
D. variations in luminosity help life to develop
