Reading Comprehension (Unseen) Passage Set - 15

Read the following passage and answer the questions that follow :-

The idea that coffee is bad for heart pops up periodically. It was found that regularly drinking very strong coffee could sharply increase cholesterol levels. Researchers even isolated fat like chemicals, cafestol and kahweol, responsible for the rise. It turned out that the European brewing method – boiling water sits on the coffee grounds for several minutes before straining – produces high concentrations cafestol and kahweol. By contrast, the filter and percolation methods remove all but a trace of these chemicals. Moreover, the studies involved large amounts of coffee – five to six cups a day. Moderate coffee drinkers down only two cups. Research has also shown that regular, moderate coffee drinking does not dangerously raise blood pressure. And studies have failed to substantiate fears that coffee might trigger abnormal heart rhythms (arrhythmias) in healthy people. "For heart disease, I think the issue is closed," says Meir Stampfer, an epidemiologist at Harvard who has studied many aspects of coffee and health. "Coffee drinking at reasonable levels is unrelated to heart risk."Evidence suggests that coffee may help fend off Parskinson's disease. A 30-year study of 8000 Japanese- American men found that avid coffee drinkers had one-fifth the risk of those who didn't drink the brew. Scientists at Massachusetts General Hospital, USA, found indirect evidence that Caffeine the habit forming stimulant in coffee – may actually combat Parkinson's. The caffeine seemed to protect mice brain cells from depletion of the nerve chemical dopamine – the problem underlying Parkinson's in humans. However, these are preliminary findings; human studies have not consistently supported caffeine's protective role. 

A) State whether the following statements are True or False. Write 'T' for True and 'F' for False :-

i) Coffee triggers arrhythmias in humans. 

ii) The European brewing method produces cafestol and kahweol. 

iii) Coffee prevents Parkinson's disease. 

iv) Depletion of the nerve chemical dopamine causes Parkinson's disease. 

B) Answer each of the following questions in about 30 words :- 

i) What happens while brewing coffee in the European method? 

ii) How does coffee combat Parkinson's disease? 

iii) Does coffee have any effect on blood pressure?
