Living things include both the visible world of animals, plants, and fungi as well as the invisible world of bacteria and viruses. On a basic level, we can say that life is ordered. Organisms have an enormously complex organization. We're all familiar with the intricate systems of the basic unit of life, the cell. Life can also "work." Living creatures can take in energy from the environment. This energy, in the form of food, is transformed to maintain metabolic processes and for survival. Life grows and develops. This means more than just replicating or getting larger in size. Living organisms also have the ability to rebuild and repair themselves when injured. Life can reproduce. Think about the last time you accidentally stubbed your toe. Almost instantly, you moved back in pain. Finally, life can adapt and respond to the demands placed on it by the environment. There are three basic types of adaptations that can occur in higher organisms.
Reversible changes occur as a response to changes in the environment. Let's say you live near sea level and you travel to a mountainous area. You may begin to experience difficulty breathing and an increase in heart rate as a result of the change in altitude. These symptoms go away when you go back down to sea level.
Body-related changes occur as a result of prolonged changes in the environment. Using ther previous example, if you were to stay in the mountainous area for a long time, you would notice that your heart rate would begin to slow down and you would begin to breath normally. These changes are also reversible. Genotypic changes (caused by genetic mutation) take place within the genetic makeup of the organism and are not reversible. An example would be the development of resistance to pesticides by insects and spiders.

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.
We get great pleasure from reading. The more advanced a man is, the greater delight he will find in reading. The ordinary man may think that subjects like philosophy or science are very difficult and that if philosophers and scientists read these subjects, it is not for pleasure.
But this is not true. The mathematician finds the same pleasure in his mathematics as the school boy in an adventure story. For both, it is a play of the imagination, a mental recreation and exercise. The pleasure derived from this activity is common to all kinds of reading. But different types of books give us different types of pleasure. First in order of popularity is novel-reading. Novels contain pictures of imaginary people in imaginary situations, and give us an opportunity of escaping into a new world very much like our world and yet different from it. Here we seem to live a new life, and the experience of this new life gives us a thrill of pleasure. Next in order of popularity are travel books, biographies and memoirs. These tell us tales of places we have not seen and of great men in whom we are interested.
Some of these books are as wonderful as novels, and they have an added value that they are true. Such books give us knowledge, and we also find immense pleasure in knowing details of lands we have not seen and of great men we have only heard of. Reading is one of the greatest enjoyments of life. To book-lovers, nothing is more fascinating than a favorite book. And, the ordinary educated man who is interested and absorbed in his daily occupation wants to occasionally escape from his drudgery into the wonderland of books for recreation and refreshment.
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.
Just two months after the flight of Apollo 10, the Apollo 11 astronauts made their historic landing on the surface of the Moon. This momentous trip for humanity also provided scientists with an abundance of material for study; from rock and soil samples brought back from the Moon, scientists have been able to determine much about the composition of the Moon (as well as to draw) inferences about the development of the Moon from its composition.
The Moon soil that came back on Apollo 11 contains small bits of rock and glass which were probably ground from larger rocks when meteors impacted with the surface of the Moon. The bits of glass are spherical in shape and constitute approximately half of the Moon soil. Scientists found no trace of animal or plant life in this soil.
In addition to the Moon soil, astronauts gathered two basic types of rocks from the surface of the Moon: Basalt and breccia. Basalt is a cooled and hardened volcanic lava common to the Earth. Since basalt is formed under extremely high temperatures, the presence of this type of rock is an indication that the temperature of the Moon was once extremely hot. Breccia, the other kind of rock brought back by the astronauts, was formed during the impact of falling objects on the surface of the Moon. It consists of small pieces of rock compressed together by the force of impact. Gases such as hydrogen and helium were found in some of the rocks, and scientists believe that these gases were carried to the Moon by the solar wind, the streams of gases that are constantly emitted by the Sun.
Question 29: It is implied in the passage that scientists believe that the gases found in the Moon rocks
