27. 

Statements: In a recent survey report, it has been stated that those who undertake physical exercise for at least half an hour a day are less prone to have any heart ailments.

Conclusions:

  1. Moderate level of physical exercise is necessary for leading a healthy life.
  2. All people who do desk-bound jobs definitely suffer from heart ailments.

[A]. Only conclusion I follows
[B]. Only conclusion II follows
[C]. Either I or II follows
[D]. Neither I nor II follows
[E]. Both I and II follow

Answer: Option A

Explanation:

The statement mentions that chances of heart ailments are greatly reduced by a regular half-hour exercise. So, I follows. However, it talks of only reducing the probability which does not mean that persons involved in sedentary jobs shall definitely suffer from heart ailments. So, II does not follow.

Could any one say why do we specific way of explaining the exercise as moderate.

@vamsi--
Physical exercise for at least half an hour a day ---This is explicitly mentioned in the statement that's why moderate.

Moderate is too vague. Why would half an hour a day be considered moderate when no benchmark is mentioned and moderate "level" does not necessarily have to be measured by time.

Just because one may be less prone to HD does not mean the exercise is a sure bet. I say neither answer is implicit.

Option A is false Telling that half an hour of exercise reduces heart trouble does not say that it is the only way and so it does not follows that it is a necessity (logical error) for an healthy life. Replacing your heart by an indefectible one will give you also an healthy life, even a better one. Does it already exist It's another question.

The use of the word necessary creates doubts over the truth of the conclusion I. There are alternative ways to remain healthy.

Ranju said: (Jun 1, 2016)  
Moderate exercise nowhere defined in the statement. So, the conclusion I does not follows.

A report of survey findings is in no way "fact". Surveys are as biased as the people taking them. So, the conclusion is incorrect.
