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.

There was a man who had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them each on a quest, in turn, to go and look at a pear tree that was a great distance away. The first son went in the winter, the second in the spring, the third in summer, and the youngest son in the fall. When they had all gone and come back, he called them together to describe what they had seen.

The first son said that the tree was ugly, bent, and twisted. The second son said no – it was covered with green buds and full of promise. The third son disagreed, he said it was laden with blossoms that smelled so sweet and looked so beautiful, it was the most graceful thing he had ever seen. The last son disagreed with all of them; he said it was ripe and drooping with fruit, full of life and fulfilment.

The man then explained to his sons that they were all right, because they had each seen but one season in the tree’s life. He told them that you cannot judge a tree, or a person, by only one season, and that the essence of who they are – and the pleasure, joy, and love that come from that life – can only be measured at the end, when all the seasons are up. If you give up when it’s winter, you will miss the promise of your spring, the beauty of your summer, fulfilment of your fall.

Don’t judge a life by one difficult season. Don’t let the pain of one season destroy the joy of all the rest.

Read the following passage and mark the letter A, B, C, or D on your answer answer to each of the questions.

One of the most interesting authors of the twentieth century, J.R.R. Tolkien, achieved fame through his highly inventive trilogy, The Lord of the Rings. Born in 1892, Tolkien received his education from Oxford and then served in World War I. After the war, he became a professor of Anglo-Saxon and English language and literature at Oxford University.

Although published in 1965, the three books that comprise The Lord of the Rings were written in intervals from 1936 to 1949. This was mainly due to Tolkien’s responsibilities as a professor and the outbreak of World War II. By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien. The trilogy is remarkable not only for its highly developed account of historical fiction but also its success as a modern heroic epic. The main plot chronicles the struggle between good and evil kingdom as they try to acquire a magic ring that has the power to rule the world. The novels, which are set in a time called Middle Earth, describe a detailed fantasy world. Established before humans populated the Earth, Middle Earth was inhabited by good and evil creatures such as hobbits, dwarves, elves, monsters, wizards, and some humans. The characters and the setting of Middle Earth were modeled after mythological stories from Greece and Northern Europe.

Although readers have scrutinized the texts for inner meaning and have tried to connect the trilogy with Tolkien’s real life experiences in England during World War II, he denies the connection. He claims that the story began in his years as an undergraduate student grew out of his desire to create mythology and legends about elves and their language.

Tolkien was a masterful fantasy novelist who used his extensive knowledge of folklore to create a body or work that is still read and enjoyed throughout the world today.

The following sentence could be added to paragraph 2. Where would it best fit into this paragraph?

“Once the ring is found by hobbit, a wizard selects a group to take the ring to the volcano where it was forged and destroy it.”

A. After the sentence that ends with “heroic epic”

B. After the sentence that ends with “fantasy world”

C. After the sentence that ends with “rule the world”

D. After the sentence that ends with “monster, wizards, and some humans”

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 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 extrateưestrial life forms might be like.

What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s 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 bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the 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 orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly 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 giants, 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.
