Although aspirin has been proven to eliminate moderate fever associated with some illnesses, many doctors no longer routinely recommend its use for this purpose. A moderate fever stimulates the activity of the ody's disease-fighting white blood cells and also inhibits the growth of many strains of disease-causing bacteria.

If the statements above are true, which of the following conclusions is most strongly supported by them?

(A) Aspirin, an effective painkiller, alleviates the pain and discomfort of many illnesses.
(B) Aspirin can prolong a patient's illness by eliminating moderate fever helpful in fighting some diseases.
(C) Aspirin inhibits the growth of white blood cells, which are necessary for fighting some illnesses.
(D) The more white blood cells a patient's body produces, the less severe the patient's illness will be.
(E) The focus of modern medicine is on inhibiting the growth of disease-causing bacteria within the body.

The answer is B

It cannot be 'B'.
'.... waves do, will, it is hoped, enable' -> is incorrect!!!!

(A) either now or within a few years will be economically competitive with
conventional sources of heat and power
(B) will either be economically competitive with conventional sources of heat and
power within a few years or are so now
(C) will be economically competitive with conventional sources of heat and
power either now or within a few years
(D) either are now economically competitive with conventional sources of heat
and power or will be so within a few years
(E) are either now or will be within a few years economically competitive with
conventional sources of heat and power

Dude, dont post the answers. You are killing the purpose of this thread. Let the junta's try first. [].

'C' is wrong.....
the usage is 'either THIS or THAT .....' and not the other way round as shown in 'C'......
'D' is indeeed correct dude....

[nairpraveenk]

Try this also dudes......

A study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.

Which of the following, if true, most seriously weakens the argument above?

(A) Married couples in which both spouses follow the same sleeping and waking patterns also occasionally have arguments than can jeopardize the couple's marriage.
(B) The sleeping and waking cycles of individuals tend to vary from season to season.
(C) The individuals who have sleeping and waking cycles that differ significantly from those of their spouses tend to argue little with colleagues at work.
(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.
(E) According to a recent study, most people's sleeping and waking cycles can be controlled and modified easily.


Please post the analysis also!!

(E) The focus of modern medicine is on inhibiting the growth of disease-causing bacteria within the body.

I think the answer should be B. From the first line "although aspirin has been proven to eliminate moderate fever associated with some illnesses", we can infer that use of aspirin to curb the mild fever associated with the illness actually prolongs the illness.
