Q15

by jayparkcom Wed Oct 24, 2012 10:52 pm

Can someone help me why D is wrong?

I eliminate A,B,and C off the bet.

I mean I see E was listed as the third reason to explain that PCB was the contributor not P brevis; yet doesn't the alternative explanation talks about D?

EDIT- wait... is it wrong because it talks about fish?

Nice work - yeah, you found the wrinkle in (D).

If you happened to recall that "fish eaten by the dolphins" appeared in the passage, you can try to find where that phrase occurred.

It comes from line 30-31.
"researchers believe brevetoxin accumulated in fish and then was ingested by dolphins that preyed on them".

So the whole "poisonous food supply" idea was a 3rd paragraph idea, not a 4th paragraph one.

The danger of PCBs is just the dolphins' exposure to them, period.

Good luck.
