Premise: In case of acute Cirrhosis, the level of blood fat decreases. High level of fat is required to overcome this situation.
Conclusion: High fat diet is not recommended in such a situation even if blood has low fat.
Prethinking Premise: We need to find a gap where high fat level food is not recommended even if the fat level in blood is low. In such type of questions, generally an assumption exists which will give proper reasoning about the conclusion. e.g. High fat level might cause some other disease if high level food is consumed.
(A) The blood fat level for patients cured of acute Cirrhosis is on average the same as that for other normal people. -
Not relevant to the conclusion, just a fact and can be ignored(B) Several symptoms of Cirrhosis have been have been detected in laboratory animals which have been fed with large doses of artificial fats, though the results were erratic and inconclusive. -
We're not worried if animals/humans are consuming artificial fat or organic fat(C) Mild affectation of Cirrhosis can lead to acute cirrhosis only when liver absorbs large quantities of fat from the patient’s blood stream . -
This seems reasonable where the condition itself is caused by fat absorption from lever. In that case, if some person with Cirrhosis eat more fat, he/she might go into chronic state.(D) People who have acute cirrhosis respond very slowly to dietary changes of food fats. -
That seemed reasonable initially but even if a person respond slowly, he/she can make changes to his/her diet over time. So, the negation of this assumption doesn't break conclusion.(E) Acute Cirrhosis is a pre-cursor of many such dreaded diseases such as heart-attack and Kidney failure etc -
Not at all related to why more fat shouldn't be consumed.
