Recent technological advances in manned undersea vehicles have overcome some of the limitations of divers and diving equipment. Without vehicles, divers often become sluggish and their mental concentration was limited. Because of undersea pressure that affected their speech organs, communication among divers was difficult or impossible. But today, most oceanographers make observations by the means of instruments that are lowered into the ocean or from samples taken from the water direct observations of the ocean floor are made not only by divers of more than seven miles and cruise at the depth of fifteen thousand feet. Radio equipment buoys can be operated by remote control in order to transmit information back to land based laboratories, including data about water temperature, current and weather. Some of mankind’s most serous problems, especially those concerning energy and food, may be solved with the help of observations made by these undersea vehicles.

With what topic is the passage primary concerned?

Gases emitted by motor vehicles are harmful to humans. The more such gases are inhaled, the more damage is done to one's respiratory system. When exercising, larger volumes of air pass through the respiratory system.

Which of the following conclusions is most strongly supported by the information above??

A popular theory explaining the evolution of the universe is known as the Big Bang Model. According to the model at some time between twenty billion years ago, all present matter and energy were compressed into a small ball only a few kilometers in diameter. It was, in effect, an atom that contained in the form of pure energy all of the components of the entire universe. Then, at a moment in time that astronomers refer to as T = 0, the ball exploded, hurling the energy into space. Expansion occurred. As the energy cooled most of it became matter in the form of protons, neutrons and electrons. These original particles combined to form hydrogen and helium and continued to expand. Matter formed into galaxies with stars and planets.

Which of the following statements allows one to determine whether the average of the grades Carla achieved in the five courses was higher than the average of the grades Joel achieved in those courses?

We are profoundly ignorant about the origins of language and have to content ourselves with more or less plausible speculations. We do not even know for certain when language arose, but it seems likely that it goes back to the earliest history of man, perhaps half a million years. We have no direct evidence, but it seems probable that speech arose at the same time as tool making and the earliest forms of specifically human cooperation. In the great Ice Ages of the Pleistocene period, our earliest human ancestors established the Old Stone Age culture; they made flint tools and later tools of bone, ivory, and antler; they made fire and cooked their food; they hunted big game, often by methods that called for considerable cooperation and coordination. As their material culture gradually improved, they became artists and made carvings and engravings on bones and pebbles, and wonderful paintings of animals on the walls of caves. It is difficult to believe that the makers of these Paleolithic cultures lacked the power of speech. It is a long step Admittedly, from the earliest flint weapons to the splendid art of the late Old Stone Age: the first crude flints date back perhaps to 500,000 B.C., while the finest achievements of Old Stone Age man are later than 100,000 B.C.; and, in this period, we can envisage a corresponding development of language, from the most primitive and limited language of the earliest human groups to a fully developed language in the flowering time of Old Stone Age culture.

How did language arise in the first place? There are many theories about this, based on various types of indirect evidence, such as the language of children, the language of primitive societies, the kinds of changes that have taken place in languages in the course of recorded history, the behavior of higher animals like chimpanzees, and the behavior of people suffering from speech defects. These types of evidence may provide us with useful pointers, but they all suffer from limitations, and must be treated with caution. When we consider the language of children, we have to remember that their situations are quite different from that of our earliest human ancestors, because the child is growing up in an environment where there is already a fully developed language, and is surrounded by adults who use that language and are teaching it to him. For example, it has been shown that the earliest words used by children are mainly the names of things and people (“Doll,” “Spoon,” “Mummy”): but, this does not prove that the earliest words of primitive man were also the names of things and people. When the child learns the name of an object, he may then use it to express his wishes or demands: “Doll!: often means “Give me my doll!” Or “I’ve dropped my doll: pick it up for me!”; the child is using language to get things done, and it is almost an accident of adult teaching that the words used to formulate the child’s demands are mainly nouns, instead of words like “Bring!”’ “Pick up!”; and so on.

If we accept that primitive man existed for a very long period of time without language, then we may assume that
