A leading question among anthropologists is: what exactly led to the development of human cities? Basically, modern humans have existed on earth for over 100,000 years. Yet it is only in the last 8,000 years that they have begun to gather in significant numbers and form cities. Prior to that period, humans existed in small family or tribal groups, generally consisting of fewer than 100 individuals. What, then, led humans to make the dramatic shift from living in small groups to living in large, organized cities? It seems that the development of cities required a particular set of circumstances.
First, it required a minimum population density. For much of their early history, humans existed only in small numbers. This is due to the fact that early humans relied on hunting and gathering wild foods for their survival. Even the most fertile land would only support a relatively small number of predators, so it was not until humans began to practice agriculture that they were able to gather in large enough numbers to form cities.
Furthermore, the development of a city could only be possible if a large number of people shared a common language, culture and religion. Without such unifying factors, a cooperative, peaceful existence among large numbers of people would have been impossible.
Finally, it seems that early humans needed to be faced with a large problem, which one small group of individuals could not solve on its own. Only when large-scale cooperation was needed to overcome a problem would humans come together to form cities
Which of the following enabled people to live together in peace?
A. A large area of fertile land
B. A shared belief and value
C. A large and complicated problem
D. A group with a minimal number of members

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.
The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 25 percent helium by weight and somewhat less than 75 percent hydrogen.
Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic rays are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn’t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.
Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significant greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.
However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperature were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled so sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formations of helium went on for only relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.
Most of the helium in the universe was formed ______
A. during the first minute of the universe's existence
B. in a very short time
C. in interstellar space
D. before most of the hydrogen
Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.
During the past half-century, our species has embarked on a remarkable social experiment. For the first time in human history, great numbers of people - at all ages, in all places, of every political persuasion - have begun settling down as singletons. Until the second half of the last century, most of us married young and parted only at death. If death came early, we remarried quickly; if late, we moved in with family, or they with us. Now we marry later. We divorce, and stay single for years or decades.
The rise of living alone has produced significant social benefits, too. Young and middle-aged solos have helped to revitalise cities, because they are more likely to spend money, socialise and participate in public life. Contemporary solo dwellers in the US are primarily women: about 18 million, compared with 14 million men. The majority, more than 16 million, are middle-aged adults between the ages of 3S and 64. The elderly account for about 11 million of the total. Young adults between 18 and 34 number increased more than 5 million, compared with 500,000 in 1950, making them the fastest-growing segment of the solo-dwelling population.
Despite fears that living alone may be environmentally unsustainable, solos tend to live in apartments rather than in big houses, and in relatively green cities rather than in car-dependent suburbs. There's good reason to believe that people who live alone in cities consume less energy than if they coupled up and decamped to pursue a single-family home.
The best title for this passage could be _________.
A. the rise in solo living
B. figures about solo dwellers in the US
C. the increase in divorce
D. solos have tendency to live in small houses
