Thanks guys for participating! Above there are the solutions, I will keep them here for one day before splitting the topic
The average level of fat in the blood of people suffering from acute cases of disease W is lower than the average level for the population as a whole.
Nevertheless, most doctors believe that reducing blood-fat levels is an effective way of preventing acute W.
Which one of the following, if true, does most to justify this apparently paradoxical belief?
(A) The blood level of fat for patients who have been cured of W is on average the same as that for the population at large.
This option does not affect the paradox at all.
(B) Several of the symptoms characteristic of acute W have been produced in laboratory animals fed large doses of a synthetic fat substitute, though acute W itself has not been produced in this way.
The text talks about humans, option B talks about animals. We are not sure that those effect can translate.
(C) The progression from latent to acute W can occur only when the agent that causes acute W absorbs large quantities of fat from the patient's blood.
CORRECT: low levels of fat prevent acute W, so the paradox is solved. If in the blood the quantity of fat is low, then W cannot absorb ""large quantities of fat".
(D) The levels of fat in the blood of patients who have disease W respond abnormally slowly to changes in dietary intake of fat.
Out of scope.
(E) High levels of fat in the blood are indicative of several diseases that are just as serious as W.
Out of scope.
