In the following question, apassage is given which describes asituation. From the given options, markthe correct inference that can be drawnfrom the passage. If none of theinferences follow, mark option 5, \u201CNoneof these\u201D as the answer.In nearly all human populations amajority of individuals can taste theartificially synthesized chemicalphenylthiocarbonide (PTC). However,the percentage varies dramatically--from as low as 60% in India to as highas 95% in Africa. That thispolymorphism is observed in non-human primates as well indicates a longevolutionary history which, althoughobviously not acting on PTC, mightreflect evolutionary selection for tastediscrimination of other, more significantbitter substances, such as certain toxicplants. Correct Answer Only a minority of the human\population have an indeterminant taste\profile. The passage clearly states that several characteristics are shared between humans and primates with respect to their taste profiles. It also states that it is because of evolution. But to infer that both species share the same profile would be incorrect making option a incorrect. The passage is all about the human ability to discern different tastes. One cannot infer about the likability of certain tastes from the given passage making option 2 incorrect. In the first sentence itself the passage talks about how majority of the human population can taste a certain artificial flavour. Thus, it can be inferred that majority of the human population have a determinant taste profile making the opposite as stated in option 3 also correct. This also makes option 4 incorrect.
