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 36 to 42.

Beads were probably the first durable ornaments humans possessed, and the intimate relationship they had with their owners is reflected in the fact that beads are among the most common items found in ancient archaeological sites. In the past, as today, men, women, and children adorned themselves with beads. In some cultures still, certain beads are often worn from birth until death, and then are buried with their owners for the afterlife. Abrasion due to daily wear alters the surface features of beads, and if they are buried for long, the effects of corrosion can further change their appearance. Thus, interest is imparted to the bead both by use and the effects of time. 

Besides their wearability, either as jewelry or incorporated into articles of attire, beads possess the desirable characteristics of every collectible, they are durable, portable, available in infinite variety, and often valuable in their original cultural context as well as in today's market. Pleasing to look at and touch, beads come in shapes, colors, and materials that almost compel one to handle them and to sort them. 

Beads are miniature bundles of secrets waiting to be revealed: their history, manufacture, cultural context, economic role, and ornamental use are all points of information one hopes to unravel. Even the most mundane beads may have traveled great distances and been exposed to many human experiences. The bead researcher must gather information from many diverse fields. In addition to having to be a generalist while specializing in what may seem to be a narrow field, the researcher is faced with the problem of primary materials that have little or no documentation. Many ancient beads that are of ethnographic interest have often been separated from their original cultural context. 

The special attractions of beads contribute to the uniqueness of bead research. While often regarded as the "small change of civilizations", beads are a part of every culture, and they can often be used to date archaeological sites and to designate the degree of mercantile, technological, and cultural sophistication.

Knowledge of the history of some beads may be useful in the studies done by which of the following _________.

A. Anthropologists 

B. Agricultural experts  

C. Medical researchers 

D. Economists

Translate into Vietnamese: Humans were in America 100,000 years earlier than we thought, study claims The remains of a mastodon discovered during a routine excavation in California shows possible human activity in North America 130,000 years ago -- or about 115,000 years earlier than previously thought.

Paleontologists with the San Diego Natural History Museum discovered the remains of the elephant-like animal more than 20 years ago. But it wasn't until now that scientists were able to accurately date the findings, and possibly rewrite the history of the New World as we know it.

"This is a whole new ball game," Steve Holen, co-director of the Center for American Paleolithic Research and the paper's lead author, told CNN. The discovery changes the understanding of when humans reached North America. The study, to be published this week in the science journal Nature, said the numerous limb bones fragments of a young male mastodon found at the site show spiral fractures, indicating they were broken while fresh.

Những vẫn còn của một voi răng mấu phát hiện trong một cuộc khai quật thường lệ ở California cho thấy hoạt động của con người có thể ở Bắc Mỹ 130.000 năm trước--hoặc khoảng 115.000 năm sớm hơn so với trước đây nghĩ.
