Nicotine has long been known to cause heart attacks and high blood pressure. Yet a recent study has shown that the incidence of heart attacks and high blood pressure is significantly higher among cigarette smokers who do not chew tobacco than among nonsmokers exposed to an equal amount of nicotine through tobacco chewing.
Which one of the following, if true, helps LEAST to resolve the apparent discrepancy described above?
(A) People who smoke but do not chew tobacco tend to exercise less than those who chew tobacco but do not smoke.
(B) Chemicals other than nicotine present in chewing tobacco but not present in cigarette smoke mitigate the effects that nicotine has on the cardiovascular system.
(C) People who chew tobacco but do not smoke tend to have healthier diets than those who smoke but do not chew tobacco.
(D) Chemicals other than nicotine present in chewing tobacco but not present in cigarette smoke can cause cancer.
(E) Chemicals other than nicotine present in cigarette smoke but not present in chewing tobacco raise blood pressure.

A study reveals that people who chew tobacco have higher heart attacks and high blood pressure than people who chew tobacco, even though Nicotine is present in both of these items.
any option that helps to understand why chewing tobacco is less harmful than cigarette smoking is not the correct answer.
(A) People who smoke but do not chew tobacco tend to exercise less than those who chew tobacco but do not smoke.
This explains why people who chew tobacco get less heart attacks and high blood pressure than people who smoke.
(B) Chemicals other than nicotine present in chewing tobacco but not present in cigarette smoke mitigate the effects that nicotine has on the cardiovascular system.
This explains why chewing tobacco is less harmful than smoking cigarette
(C) People who chew tobacco but do not smoke tend to have healthier diets than those who smoke but do not chew tobacco.
same as option A & B, this helps to understand the effects mentioned in the passage
(D) Chemicals other than nicotine present in chewing tobacco but not present in cigarette smoke can cause cancer.
This talks about some other disease, cancer, which can be caused by chewing tobacco, but does nothing to explain why chewing tobacco might not cause higher heart attacks and high blood pressure than smoking cigarette
(E) Chemicals other than nicotine present in cigarette smoke but not present in chewing tobacco raise blood pressure.
this explains why smoking cigarette causes high blood pressure

Which one of the following, if true, helps LEAST to resolve the apparent discrepancy described above?
(A) People who smoke but do not chew tobacco tend to exercise less than those who chew tobacco but do not smoke.
This explains why People who some but do not chew tobacco have higher blood pressure and greater incidence of heart attacks
(B) Chemicals other than nicotine present in chewing tobacco but not present in cigarette smoke mitigate the effects that nicotine has on the cardiovascular system.
This explains that even though both chewing and smoking have the same amount of nicotine, it is not likely for a tobacco chewing person to have such diseases than for the smokers.
(C) People who chew tobacco but do not smoke tend to have healthier diets than those who smoke but do not chew tobacco.
This explains why people who chew tobacco are healthier
(D) Chemicals other than nicotine present in chewing tobacco but not present in cigarette smoke can cause cancer.
This talks about cancer, a disease that the argument does not mention
(E) Chemicals other than nicotine present in cigarette smoke but not present in chewing tobacco raise blood pressure.
This presents another factor for a smoker to have higher blood pressure and greater incidences of the heart attacks.
