VI. Read the text and classify the following statements.

There are eight other planets that travel around the sun. These planets, in order, include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Earth is located between Venus and Mars. The path the planets use when traveling around the sun is oval-shaped and is called its orbit. Each of the planets in the solar system take a different amount of time to orbit the Sun.

Earth takes 365 days or one year to orbit the Sun. The other planets take more or less time to orbit the Sun. It takes Mercury 88 days to travel around the Sun, which is the shortest orbit time compared to other planets. The planet taking the longest time to go around the Sun is Neptune. It takes Neptune almost 165 years to travel around the Sun.

Normally, planets located closer to the sun are hotter than planets farther away. Mercury is the planet nearest the sun, and it can have a temperature of 427°C– much hotter than an oven. Venus is not the planet nearest the sun, but it is the hottest, because it has thick clouds. These clouds let the sun’s heat in, but do not let it out. The temperature on Venus can be 460°C.

The four inner planets, Mercury, Venus, Earth, and Mars are made of rock containing many different minerals. The four outer planets, Jupiter, Saturn, Uranus, and Neptune are mostly made up of different gases. Jupiter is made mainly of helium, hydrogen, and water. The four outer planets also have rings that encircle them, with Saturn having the most rings.

Other objects in space include the moons of these six planets. A moon is a celestial object (object in space) that orbits another body in space. There are approximately 173 moons throughout the solar system. Earth has a single moon, Mercury and Venus have none, and the planet with the most moons is Jupiter with 63. Not far behind Jupiter is Saturn with 62 moons.Mars has 2 moons named Phobos and Deimos.

Classify the following statements (1-12) as they relate to the given planets. Write the names of the planet next to the statements.

Mercury	Earth	Jupiter	Uranus
Venus	Mars	Saturn	Neptune

1. It is the farthest planet from the Sun. ………………..

2. It is the hottest planet. ………………..

3. It takes the shortest time to orbit the Sun. ………………..

4. It takes the longest time to go around the Sun. ………………..

5. The temperature on its surface is about 427°C. ………………..

7. It has only one moon. ………………..

8. It has 63 moons. ………………..

9. It has 62 moons. ………………..

10. It is located between Venus and Mars. ………………..

11. It has two moons known as Deimos and Phobos. ………………..

Mercury and Pluto are probably the most difficult to research because of their position in the solar system. Mercury is so close to the sun that with our current technology a space shuttle would burn up before it even reached its atmosphere. Pluto is so far away that some scientists believe that it may not even be a planot but a large asteroid or comet. A space shuttle can not trave that far away because it is so far away from the sun that it would freeze.

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

In can be inferred from paragraph 4 that______.

A. most stars have more than two planets in their habitable zone

B. no star has more than two planets in its habitable zone

C. it is not possible for a star to have three planets with life on them

D. for life to develop, a star must have at least two planets in its habitable zone
