I'm having some trouble setting this one up. Your help is much appreciated!

Bird-watchers explore a forest to see which of the following six kinds of birds -- grosbeak, harrier, jay, martin, shrike, wren -- it contains. The findings are consistent with the following conditions:

If harriers are in the forest, then grosbeaks are not.
If jays, martins, or both are in the forest, then so are harriers.
If wrens are in the forest, then so are grosbeaks.
If jays are not in the forest, then shrikes are.

12. Suppoose the condition is added that if shrikes are in teh forest, then harriers are not. If all other conditions remain in effect, then which one of teh following could be true?
a) the forest contains both jays and shrikes
b) the forest contains both wrens and shrikes
c) the forest contains both martins and shrikes
d) jays are not in the forest, whereas martins are
e) only two of the six kinds of birds are not in the forest

How about you list all the questions together instead of on five different threads... just my 2 cents.
