Q18)More women than men suffer from Alzheimer’s disease—a disease that is most commonly contracted by elderly persons. This discrepancy has often been attributed to women’s longer life span, but his theory may be wrong. A recent study has shown that prescribing estrogen to women after menopause, when estrogen production in the body decreases, may prevent them from developing the disease. Men’s supply of testosterone may help safeguard them against Alzheimer’s disease because much of it is converted by the body to estrogen, and testosterone levels stay relatively stable into old age.
Which of the following most accurately expresses the main conclusion of the argument?
(A) A decrease in estrogen, rather than longer life span, may explain the higher occurrence of Alzheimer’s disease in women relative to men.
(B) As one gets older, one’s chances of developing Alzhimer’s disease increase.
(C) Women who go through menopause earlier in life than do most other women have an increased risk of contracting Alzheimer’s disease.
(D) The conversion of testosterone into estrogen may help safeguard men from Alzheimer’s disease.
(E) Testosterone is necessary for preventing Alzheimer’s disease in older men.

A

Because author presents an arguememt - More women sufer with Alz. than men because they have longer life, the NEGATES it. Says that is not correct, then gives reason what else could be causing it/preventing it. i.e Estogen.
Only A properly expresses an alternate to an existing theory, thus correct

For the main conclusion, the correct answer choice will be rephasing of the main conclusion of the argument.
i.e:A decrease in estrogen, rather than longer life span, may explain the higher occurrence of Alzheimer’s disease in women relative to men.

I agree with A.

(A) A decrease in estrogen, rather than longer life span, may explain the higher occurrence of Alzheimer’s disease in women relative to men. Summarizes the conclusion the best
(B) As one gets older, one’s chances of developing Alzhimer’s disease increase. True, but not the main point of the arguement
(C) Women who go through menopause earlier in life than do most other women have an increased risk of contracting Alzheimer’s disease.This is implied, but not the conclusion of the argument
(D) The conversion of testosterone into estrogen may help safeguard men from Alzheimer’s disease.True, but not the conclusion
(E) Testosterone is necessary for preventing Alzheimer’s disease in older men.same as D
