Significant beneficial effects of smoking occur primarily in the area of mental health, and the habit originates in a search for contentment. The life expectancy of our people has increased greatly in recent years; it is possible that the relaxation and contentment and enjoyment produced by smoking has lengthened many lives. Smoking is beneficial.
Which of the following, if true, weaken the above conclusion?
(A)That cigarettes are a major health hazard cannot be traced to the willful act of any human or organization.
(B)The government earns millions of dollars from the tobacco tax and tens of thousands of civilians are employed in the tobacco industry.
(C)The evidence cited in the statement covers only one example of the effects of cigarette smoking.
(D)no mention is made of possible harmful sideeffects of smoking
(E)No statistical evidence has proven a link between smoking and longevity
conclusion => smoking is beneficial
weaken the conclusion => smoking is not or to a lesser extent beneficial
the new information that no mention is made of possible negative side effects would weaken the conclusion becauce - by surprise - smoking is not so beneficial as it seems
(1) P:Beneficial effect of smoking: primarily occur in area of mental health
(2) P:"Habit originates in search for contentment
(3) P:relaxation and contenetment and enjoyment by smoking --> lengthed life expectancy of our people
(4) C:Smoking is beneficial
We need a statement that negates the conclusion that smoking is beneficial
(C): Only contentment derived from smoking is covered. No other effects are covered in the passage. So we can't be too sure that smoking is beneficial in the sense it lengthens our lifespan.
I'm inclinced to pick (D) but decided to go ahead with (C).
In (D) no mention is made of possible harmful sideeffects of smoking, it simply means we're not told of harmful side-effects. What side-effects, we're not sure. The harm may be very minimal compared to benefits. So again, we can't say for sure that smoking is not beneficial.
I don't see anything wrong with (E). E is my choice.
Reason: The argument says that 'it is possible that the relaxation and contentment....' No evidence given on how possible such relationship exists (b/w smoking and longevity). I would think C is irrelevant and D is out of scope.
The argument says the longevity of people who smoke has increased, but it doesn't say that that they live longer as compared to people who donot smoke or that there is any relation between smoking & longevity.
