RC wrong-uns

I failed to notice other industries in this particular question and fell directly into the trap.

Check above one out as it is pretty damn perplexing.

A is pretty much sure based on evidence from passage, others don’t quite match the passage.

E is wrong as passage talks about all beavers know how to build, which means innate skill.
D is wrong because of permits and more likely.
C has no clue what it is talking about.
A has no any circumstantial evidence for supporting argument.

I got wrong in B, why so?
I tried to use my own senses rather than what’s given in Passage. Maintain it in your tiny brain, ETS won’t make you use inference 10% evidence, it will be evince in the para.

Passage 42

I chose B while there is no such evidence to support that particular argument. LOOK FOR DETAILS IN PASSAGE BEFORE SELECTING ONE.
And, about A, I misread it. Thus, I ignored not, read only irreconcilable.
