VARC Question 8 -
It cannot be inferred from the penultimate para that -
Answer is option D which says that the functional machinery cannot be understood without understanding the protein structures.
Reasoning for the answer is that it has not been stated that functional machinery cannot be understood without understanding the protein structures. The passage clearly says that protein makes the functional materials that makes the machinery of all living things. The structure of the proteins define the function, and we don't understand these because they are exceedingly complicated.
From this, can we not infer that if we don't understand protein structures - we won't understand function. And by extension we won't understand the machinery as well because the functions make up the machinery.
In my opinion, this is not a stretch and can be reasonable inferred. Thoughts?
