Hi greenwich,

The question asks for the statement that is the most reliable conclusion from the information. On the GMAT there is only ONE correct answer to each question, but that does not mean there are no "kind of right" answers. In essence, we are asked to compare each of the answers to find the best one.

Answer C is one of the "kind of right" answers. It seems obviously true that banning tobacco ads does not reduce the consumption of tobacco, because we are told that tobacco ads are banned in Norway but smoking is still prevalent. What we are not told in the passage is WHY smoking is still prevalent. What I mean is that we have not been given any information that might suggest alternative reasons for why teenagers still smoke.

Answer A raises the point that there must be other reasons for why teenagers still smoke.

Answers D and E are ridiculous and easily eliminated. Answer B contradicts information presented in the passage, so can also be eliminated. It really comes down to comparing C and A to find the BEST answer. As noted above, the best answer is C because it is the most reliable conclusion that can be drawn from the passage.

I hope this helps.

Why C is wrong?

The correct answer choice MUST BE TRUE.
Beware CHANGES IN SCOPE.
The passage offers information about tobacco advertising IN NORWAY.
Answer choice C draws a conclusion about tobacco advertising IN GENERAL.
It does not have to be true that banning tobacco advertising IN GENERAL has no effect simply because the ban IN NORWAY has no effect.
Eliminate C.

As Far As I know, teens/kids are indeed impressionable followers, but not leaders.If the Ads tell them that tobacco smoking is wonderful,then that's what they will think.
