(D)

causing and endangering must be parallel, so that leaves A & D. From there, D just sounds better

Shouldn't the parallel be between "causing" and "threatening" ?

Dediding between A and D is deciding between "and" and "as well as"... anybody knows a rule?

I like A by the way...

B??

ok... "endanger" and "threaten" then...

You made me see something I had missed: the threat to global ecological systems is not a second example of how human health could be endangered, but a second effect of radiation.

In that case.. B is correct...

Can some explain how the following clause fits in the sentence.
"causing a rise in the incidence of skin cancer and eye disease"

What "causing" referring to?

If causing refers to radiation, shouldn't the sentence be the following:
radiation wil endanger, cause, and threaten.

What am I missing?
Experts - could you step up any save our souls?

"causing" is not part of the parallel structure and is there to provide examples of how human life is endangered.

It is a trick to offer a parallel construction when, in fact, there is no need to employ one. Some books call such a trick Red Herring because it captures your attention and leads you in wrong direction.

old question but nice discussions...

B is only parall choice that fits into the sentence. "causing a rise in the incidence of skin cancer and eye disease" is intervening/modifying phrase...
