This is very easy one but I goofed up when I took it under test condition.... :roll:

Dutch elm disease, which is caused by the fungus C. ulmi spread by adult scolytid beetles, has already destroyed 70 percent of the elms in Greenwood Forest. Another naturally occurring fungus, P. oblonga, kills larvae of the scolytid beetle. Forest rangers plan to introduce P. oblonga into Greenwood Forest in order to save the remaining mature elms.
Which of the following, if true about P. oblonga, provides the strongest evidence that the plan will succeed?
(A) It is spread by a variety of birds that nest in trees that are the home of scolytid beetle larvae.
(B) It has been known to lie dormant within a tree for up to ten years before it begins to reproduce.
(C) It spreads more slowly than C. ulmi, under most climatic conditions.
(D) It does not destroy some commonly found subspecies of scolytid beetles.
(E) It has been known to kill maple trees by destroying their root systems.

Ughm, Straight up A.

It shows how it can be spread.

Nothing else strengthens it.

yes A.

I have similar issues. When I look at a question in isolation, I get the answer right. However, under test condition, I goof up.

A is the only option that is supporting fast spread of the P.olonga

I guess I failed to map to similar but ostensibly different information -- "introduce" and "bird spreads" -- when I was looking for probable winner, A.

OA is A indeed

All other choices besides (A) does something to weaken the argument, so (A) is the only possible choice.

B suggests it works very slow; C says the same; D undermines its effectiveness; & E talks about its side effects.
