There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in mother's body which divides to form. two separate babies. Identical twins look the same and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs at the same time, both of which grow to form. babies.

Text 4

Anthropology is the study of human beings as creatures of society. It fastens its attention upon those physical characteristics and industrial techniques, those conventions and values, which distinguish one community from all others that belong to a different tradition.

The distinguishing mark of anthropology among the social sciences is that it includes for serious study more other societies than our own. For its purposes any social regulation of mating and reproduction is as significant as our own, though it may be that of the Sea Dyaks, and have no possible historical relation to that of our civilization. To the anthropologist, our customs and those of a New Guinea tribe are two possible social schemes for dealing with a common problem, arid in so far as he remains an anthropologist he is bound to avoid any weighting of one in favor of the other, lie is interested in human behavior, not as it is shaped by one tradition, our own, but as it has been shaped by any tradition whatsoever. He is interested in a wide range of custom that is found in various cultures, and his object is to understand the way in which these cultures change and differentiated, the different forms through which they express themselves and the manner in which the customs of any peoples function in the lives of the individuals.

Now custom has not been commonly regarded as a subject of any great moment. The inner workings of our own brains we feel to be uniquely worthy of investigation, but custom, we have a way of thinking, is behavior. at its most commonplace. As a matter of fact, it is the other way round. Traditional custom is a mass of detailed behavior. more astonishing than what any one person can ever evolve in individual actions. Yet that is a rather trivial aspect of the matter. The fact of first rate importance is the predominant role that custom plays in experience and belief, and the very great varieties it may manifest.

36. According to the passage, we can say that anthropology ______.

A)can deal with human beings as one group of the creatures in the living world

B) can reveal an enormous diversity of traditions

C) can provide insights into the relationship between human beings and nature

D) can distinguish the human race from other creatures

A. is biggest than any other one

B. is bigger than any other one

C. is more bigger than any other one

D. is bigger than any one
