Read the following passage and choose the correct answer to each of the questions.
The history of clinical nutrition, or the study of the relationship between health and how the body takes in and utilizes food substances, can be divided into four distinct eras: the first began in the nineteenth century and extended into the early twentieth century when it was recognized for the first time that food contained constituents that were essential for human function and that different foods provided different amounts of these essential agents. Near the end of this era, research studies demonstrated that rapid weight loss was associated with nitrogen imbalance and could only be rectified by providing adequate dietary protein associated with certain foods.
The second era was initiated in the early decades of the twentieth century and might be called "the vitamin period. " Vitamins came to be recognized in foods, and deficiency syndromes were described. As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At that point in time, medical schools started to become more interested in having their curricula integrate nutritional concepts into the basic sciences. Much of the focus of this education was on the recognition of deficiency symptoms. Herein lay the beginning of what ultimately turned from ignorance to denial of the value of nutritional therapies in medicine. Reckless claims were made for effects of vitamins that went far beyond what could actually be achieved from the use of them.
In the third era of nutritional history in the early 1950's to mid-1960's, vitamin therapy began to fall into disrepute. Concomitant with this, nutrition education in medical schools also became less popular. It was just a decade before this that many drug companies had found their vitamin sales skyrocketing and were quick to supply practicing physicians with generous samples of vitamins and literature extolling the virtue of supplementation for a variety of health-related conditions. Expectations as to the success of vitamins in disease control were exaggerated. As is known in retrospect, vitamin and mineral therapies are much less effective when applied to health-crisis conditions than when applied to long-term problems of under nutrition that lead to chronic health problems.
Why did vitamin therapy begin losing favor in the 1950s?
A.The public lost interest in vitamins.
B.Nutritional research was of poor quality.
C.Claims for the effectiveness of vitamin therapy were seen to be exaggerated.
D.Medical schools stopped teaching nutritional concepts.

Read the following text then answer the questions that followed by circling its corresponding letter marked A, B, C or D from 38 to 42.
Sometimes you know things about people the first time you see them, for example, that you want to be friends with them or that you don’t trust them. But perhaps this kind of intuition isn’t as hard to explain as it may seem. For instance, people give out their body language signals all the time. The way you hold your body, head and arms tells people about your mood. If you hold your arms tightly at your sides, or fold them across your chest, people will generally feel that you are being defensive. Holding your head to one side shows interest in the other, while an easy, open posture indicates that you are self-confident. All this affects the way you feel about someone.
Also, a stranger may remind you of a meeting with someone. This may be because of something as simple as the fact that he or she is physically similar to someone who treated you well or badly. Your feelings about a stranger could be influenced by a smell in the air that brings to mind a place where you were happy as a child. Since even a single word can bring back a memory such as that, you may never realize it is happening.
What does the second paragraph discuss?
A.Meaning of signals one implies toward a stranger
B.Factors that cause people to act differently
C.How people usually behave to a stranger
D.Factors that may influence one’s feeling about a stranger
