Consumer: a new law requires all cigarette packaging to display a health warning, disturbing pictures of smoke related diseases, and no logos. this law will not affect smoking habit of most people who smoke cigarette regularly, since most of these people rarely look at the packaging when they take out a cigarette.
The conclusion of consumers argument follows logically if which of the following is assumed ?
(A) If implementing certain regulations on packaging of cigarette would affect the smoking habits of those who smoke regularly, those regulations should be implemented
(B) If those who regularly smoke cigarette look at a disturbing pictures of smoking related diseases frequently, it is likely to affect their smoking habits.
(C) Almost all people who regularly smoke cigarette are already familiar with the risks that smoking poses to their health.
(D) The new packaging can not affect the smoking habits of the people who regularly smoke cigarette unless they frequently look at the packaging when taking out cigarettes.
(E) Most people who regularly smoke cigarettes would be unable to describe the log of their unusual brand of cigarette if asked to do so.
Premises:
A new law needs to display a health warning and disturbing pictures.
Most people who smoke regularly, rarely look at packaging.
Conclusion: Health habits of regular smokers will not change.
What does looking at packaging have to do with change in health habits? We do not have any premise that tell us that if people do not look at packaging, their health habits will not change. The premises give us no link between looking at packaging and health habits. If we need the conclusion to follow, we need to give this essential link.
(A) If implementing certain regulations on packaging of cigarette would affect the smoking habits of those who smoke regularly, those regulations should be implemented
Which regulations should be implemented and which not is not our point of concern.
(B) If those who regularly smoke cigarette look at a disturbing pictures of smoking related diseases frequently, it is likely to affect their smoking habits.
If people regularly look at disturbing pictures, it is likely to affect their habits.
But what happens if they do not look at pictures? Does it mean it will not affect their habit? No. Go back to the conditional basics.
Given: If A, then B
A implies B
but
Not A does not imply not B.
https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/2012/1 ... tatements/The if-then statement of option (B) does not help establish that not looking at disturbing pictures means the habits will not change.
(C) Almost all people who regularly smoke cigarette are already familiar with the risks that smoking poses to their health.
We are talking about looking at packaging and not familiarity with the risks.
(D) The new packaging can not affect the smoking habits of the people who regularly smoke cigarette unless they frequently look at the packaging when taking out cigarettes.
Unless is nothing but an only if statement.
Only if regular smokers look at packaging frequently can it affect smoking habits.
Only if A, then B.
Here, not A implies not B.
So if regular smokers do not look at packaging frequently, they smoking habits are not affected.
We are given that regular smokers do not look at packaging frequently (they rarely look). So we can say that they habits will not be affected.
This is what we were looking for.
Correct.
(E) Most people who regularly smoke cigarettes would be unable to describe the log of their unusual brand of cigarette if asked to do so.
Ability to describe logo is irrelevant.
Answer (D)
