Logical Reasoning - Statement and Conclusion - Discussion
In each question below is given a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement.
- (A) If only conclusion I follows
- (B) If only conclusion II follows
- (C) If either I or II follows
- (D) If neither I nor II follows and
- (E) If both I and II follow.
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.
- Moderate level of physical exercise is necessary for leading a healthy life.
- All people who do desk-bound jobs definitely suffer from heart ailments.
First one doesn't follow either.
First, the statement DOES NOT MENTION that chances of heart ailments are GREATLY reduced by a regular half-hour exercise. It only says you are LESS PRONE (maybe you are 0.01% less prone -I wouldn't call that "greatly").
Second, we don't know for sure 30 minutes is considered "moderate".
Third, it's not a scientific paper studying cause-effect, it's A SURVEY, from which you cannot infer cause-effect.
Now, even if we did not take all that into account, and gave for it granted that "less prone" is equal to "greatly", that "moderate" is "30 mins per day", and that surveys describe cause-effect, moderate level of physical exercise is not NECESSARY for a healthy life. It is desirable, which is not quite the same. You can have a healthy life all your life (meaning literally that: no health issues -no heart problems, nor lung nor ANY- and yet you never did a moderate physical exercise in your life. If you do, you'll just REDUCE YOUR CHANCES.
Physical exercise for at least half an hour a day ---This is explicitly mentioned in the statement that's why moderate.
