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 1 to 8.

As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast lane" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.

Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.

In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.

Which of the following does the passage infer?

A. We now fully understand how risk factors trigger heart attacks. 

B. We recently began to study how risk factors trigger heart attacks. 

C. We have not identified many risk factors associated with heart attacks. 

D. We do not fully understand how risk factors trigger heart attacks.

Dịch bài đọc:

Khi bệnh tim là kẻ giết người số một ở Hoa Kỳ, nhà nghiên cứu đã ngày càng quan tâm tới việc xác định yếu tố rủi ro có thể xảy ra gây ra cơn đau tim. Chế độ ăn uống nhiều chất béo và" cuộc sống sôi động" đã được biết đến từ lâu như là nhân tố lớn góp phần tạo nên phạm vi ảnh hưởng của suy tim. Nhưng theo nghiên cứu mới, danh sách yếu tố rủi ro có thể dài hơn nhiều và hoàn toàn bất ngờ.

Suy tim, chẳng hạn, có vẻ có mùa và liên quan đến thời gian kiểu mẫu. Tỉ lệ phần trăm của cơn đau tim thường xảy ra khi trời lạnh, và vào ngày thứ hai hơn bất cứ ngày nào khác ngày trong tuần. Ngoài ra, mọi người dễ bị mắc bệnh đau tim hơn trong mấy giờ đầu sau khi thức giấc. Bác sĩ tim mạch đã quan sát hiện tượng này trong giữa năm 1980, và có từ khám phá ra một số nguyên nhân có thể. Sáng sớm tăng huyết áp, nhịp tim, và nồng độ tim kích thích hoóc - môn, cộng giảm của máu lưu thông đến tim, có thể tất cả góp phần tạo nên cao phạm vi ảnh hưởng của cơn đau tim giữa giờ 8:00 Sáng và 10:00 Sáng.

Ở nghiên cứu khác, cả sinh nhật lẫn sự độc thân bị ám chỉ là yếu tố rủi ro. Số liệu thống kê cho thấy là cơn đau tim tăng đáng kể cho cả phụ nữ và phái nam trong vài ngày ngay trước và sau ngày sinh của họ. Và đàn ông chưa vợ có nguy cơ cho cơn đau tim hơn phụ nữ. Cho dù áp lực được xem là có liên kết theo một kiểu nào đó với toàn bộ yếu tố rủi ro nêu trên, nhiều nghiên cứu tiếp diễn với hy vọng hiểu rõ hơn tại sao và cách suy tim được gây ra.

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 1 to 5.

A team of Russian scientists has challenged the theory that the woolly mammoths became extinct 10,000 years ago at the end of the Ice Age. The scientists have reported that the beasts may have survived until 2000 B.C. on an island off the coast of Siberia, where researchers uncovered 29 fossilized woolly mammoth teeth ranging in age from 4,000 to 7,000 years. The question to be asked now is, how did these prehistoric pachyderms survive in their island environment? One possibility is that they adapted to their confined surroundings by decreasing their bulk. This theory is based on their smaller tooth size, which has led scientists to believe that they were only 6 feet tall at the shoulder compared with 10 feet of their full-sized counterpart. But would this be enough to enable them to survive thousands of years beyond that of other mammoths? Researchers are still working to uncover the reasons for this isolated group's belated disappearance.

According to the scientists, the woolly mammoths may have managed to survive because they
