Smokers of pipes or cigars run a distinctly lower risk to their health

Well the task here is to find out the best reason that explains the fact that switching from smoking cigarette to cigar does not keep you back on the track of getting healthy. Given is the information " Cigars are less dangerous than cigarette".

well be begin scanning the options:

A) No explanation addressing the anomaly.
B) Again no mention of cigars. Not so classy choice.
C) This statement contradicts the given situation that cigars are somewhat better than cigarettes.
D) This statement tells another story, which is irrelevant to the context.

E is the answer.

(C) The kinds of illnesses that smokers run an increased risk of contracting develop no earlier in cigarette smokers than they do in smokers of pipes or cigar.

The sentence means that risk of getting an illness by a certain age is same for cigarette-smokers as pipe-smokers.

But the objective of the question is to find the paradox, which proves why cigarette-smokers are not likely to reduce their chance of getting an illness if they switch to smoking pipes.

(E) solves this paradox by stating that cigarette-smokers inhale smoke in a different way as opposed to non-smokers.

Smokers of pipes or cigars run a distinctly lower risk to their health than do cigarette smokers. However, whereas cigarette smokers who quit smoking altogether sharply reduce their risk of smoking-related health problems, those who give up cigarettes and take up pipes or cigars remain in as much danger as before.

Which one of the following, if true, offers the best prospects for an explanation of why the two changes in smoking habits do not both result in reduced health risks?

(A) Smokers of pipes or cigars who quit smoking thereby reduce their risk of smoking-related health problems. - WRONG. Doesn't explain why cigarettes smokers don't reduce health risk.

(B) Cigarette smokers who quit smoking for a time and who then resume cigarette smoking do not necessarily reduce their risk of smoking-related health problems. - WRONG. Doesn't explain why cigarettes smokers don't reduce health risk after switching to cigars or pipes.

(C) The kinds of illnesses that smokers run an increased risk of contracting develop no earlier in cigarette smokers than they do in smokers of pipes or cigar. - WRONG. Doesn't explain why cigarettes smokers don't reduce health risk. Irrelevant at best.

(D) At any given period in their lives, virtually all smokers smoke either cigarettes exclusively or cigars exclusively or pipes exclusively, rather than alternating freely among various ways of smoking. - WRONG. Doesn't explain why cigarettes smokers don't reduce health risk. Irrelevant like C.

(E) People who switch from cigarette smoking to smoking pipes or cigars inhale smoke in a way that those who have never smoked cigarettes do not. - CORRECT. "Those who have never smoked cigarettes" might be confusing. It can include people who smoked cigars or pipes but not cigarettes ever, not just people who never smoked.

Answer E.
