10. 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

Both A and D appear true.

A is true - because the argument talks about raising funds to preserve irreplacable exhibits.
B is not true because the argument does not talk about if the exhibits can be used for multiple studies or not.
C is wrong because there's no reference to the study of "genetic relationships" studies.
D is true because it presupposes and applies that just like eggs are valuable in establishing a relationship between decline of birds of pray and pesticides, we can predict and presuppose the exhibits that would be useful for studies in the future and can be preserved now.
E is false - it opposes the basis of contention that with greater funds exhibits can be preserved.

Between A and D, I'd go with D because there's a slight hint that the author stresses on the preservation of not the "irreplacable" exhibits but the ones that would be most valuable to science in the future.

D) seems correct because

" funds must be raised to preserve at least those exhibits that will be most valuable to science in the future "
