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 30 to 34.

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-1980s 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 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 is NOT cited as a possible risk factor?

A. having a birthday

B. getting married 

C. eating fatty foods

D. being under stress

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.

Insects' lives are very short and they have many enemies, but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look "inedible" by imitating plants is a way frequently used by insects to survive. Mammals rarely imitate plants, but many fish and invertebrates do.

 The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called "measuring worm" or "inchworm." It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind feet forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed.

 Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection; they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live.

            Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the plants that they resemble.

Which of the following is true of stick insects?

A. They make themselves look like other insects.

B. They change color to make themselves invisible.

C. They are camouflaged only when walking.

D. They resemble their surroundings all the time.

The reason women appear to be at greater risk of developing Alzheimer’s disease than men might be due to a number of genetic, anatomical and  even  social  influences,  researchers  have  suggested.  Recent figures show about 65% of those  with living with dementia in the  UK are women,  with a  similar statistic seen in the US for Alzheimer’s disease, while dementia is the leading cause of death for women in England. Alzheimer’s disease is only one of the types of dementia, but the most common form. While one explanation is that dementia risk increases with age, and women have longer life expectancies than men, new research suggests there might be more to the matter, including that protein tangles found within neurons and linked to Alzheimer’s disease might spread differently in women’s brains than men’s. The study, presented at the Alzheimer’s Association International Conference in Los Angeles by researchers from Vanderbilt University and which has not yet been peer-reviewed, used scans from a method called positron emission tomography. That allowed them to look at the way clumps of a protein called tau were spread in the brains of 123 men and 178 women without cognitive problems, as well as 101 men and 60 women with mild cognitive problems – although not yet diagnosed with Alzheimer’s disease. Cognitively normal older people often have small amounts of tau in certain areas of their brain. From the data the team could build maps showing which areas of the  brain  show  similar  signals relating to tau in the scans, suggesting they are somehow connected. “Based on that we kind of try to reconstruct the pattern of spread,” Dr Sepideh Shokouhi, who is presenting the research, told the Guardian. “It is kind of like reconstructing a crime scene.” The team says the results suggest these maps look different in women and men, suggesting tau might be able to spread more rapidly across the female brain.

Other research presented at the conference – and also not yet peer reviewed – added weight to the idea that there might be differences between men and women that affect dementia risk. Research by scientists at the University of Miami has revealed a handful of genes and genetic variants appear to be linked to Alzheimer’s disease in just one biological sex or the other. While the actual importance of these factors has yet to be unpicked, and the study only looked at white participants, the team says it underscores that there could be a genetic reason for differences in the risk of dementia in men and women, and the way it develops.

The following are the reasons for Alzheimer’s disease, EXCEPT_____

 

A. gene

Căn cứ vào các thông tin sau:

The reason women appear to be at greater risk of developing Alzheimer’s disease than men might be due to a number of genetic, anatomical and even social influences, researchers have suggested. (Đoạn 1) (Các nhà nghiên cứu đã chỉ ra rằng nguyên nhân phụ nữ dường dư có nguy cơ mắc bệnh Alzheimer cao hơn nam giới là do các tác động của gien, giải phẫu và cả của xã hội).

Alzheimer’s disease is only one of the types of dementia, but the most common form. While one explanation is that dementia risk increases with age, and women have longer life expectancies than men, new research suggests there might be more to the matter, including that protein tangles found within neurons and linked to Alzheimer’s disease might spread differently in women’s brains than men’s. (Đoạn (2) Alzheimer chỉ là một loại của bệnh mất trí nhớ, nhưng là dạng phổ biến nhất. Trong khi một giải thích khác cho rằng nguy cơ mất trí nhớ tăng lên theo tuổi tác, và phụ nữ thường có tuổi thọ lớn hơn nam giới, thì một nghiên cứu mới đã cho biết vấn đề có thể nghiêm trọng hơn, bao gồm tình trạng lộn xộn protein được tìm thấy trong nơ-ron và được cho là liên quan tới bệnh Alzheimer có thể phát triển 1 cách khác nhau trong não của phụ nữ và đàn ông).
