Millions of irreplaceable exhibits in natural history museums are currently allowed to decay. Yet without analyses of eggs from museums, the studies linking pesticides with the decline of birds of prey would have been impossible. Therefore, funds must be raised to preserve at least those exhibits that will be most valuable to science in the future.

The argument presupposes that

(A) if a museum exhibit is irreplaceable, its preservation is of an importance that overrides economic considerations
(B) the scientific analysis of museum exhibits can be performed in nondestructive way
(C) eggs of extinct species should be analyzed to increase knowledge of genetic relationships among species
(D) it can be known at this time what data will be of most use to scientific investigators in the future
(E) the decay of organic material in natural history exhibits is natural and cannot be prevented

D it must be. Because it supposes that people can know what will be valuable in future for science.

why author thinks that funds must be raised to save those X(irreplaceable exhibits ) that will be valuable to future

because without Analysis the study linking A and B is not possible.

Assumption :- Analysis does required funds to save those X
another assumption is "it is possible to save those X for future."

D what if investigators dont know what to save the conclusion is falsify

D it is.
Though Stuck between D and E.

E wrong because if the decay is natural and cannot be prevented, no amount of money would be able to save them. Hence out of scope.

Can anyone please explain to me why option E is incorrect and D is correct using the negation technique? I am still a bit confused regarding option E.
