First Experiment

1		The dark, carbonaria moths are more prevalent in woods
			A)	That are polluted and have lichen-covered tree trunks
			B)	That are not polluted and have lichen-covered tree trunks
			C)	That are polluted and have blackened tree trunks
			D)	That are not polluted and have blackened tree trunks
2		Since (man-made) pollution is a relatively recent phenomenon, it is likely that
			A)	The typical variety is the ancient variety and carbonaria arose by a recent mutation.
			B)	The carbonaria variety is the ancient variety and typical arose by a recent mutation.
			C)	Both variations are ancient.
			D)	None of the above
3		The purpose for marking the released moths with cellulose paint was
			A)	To make it easier for birds to see them
			B)	To help the moths find the mercury vapor light
			C)	To prevent the moths from leaving the immediate region
			D)	To distinguish the released moths from moths that were already in the region
4		The experimenters evaluated the level of predation by
			A)	The recapture number, and by the number that were seen to be eaten by birds
			B)	The recapture number only
			C)	The number that were seen to be eaten by birds only
			D)	None of the above
5		If the hypothesis had been incorrect, how would the data have been affected?
			A)	The data would be the same.
			B)	There would have been many more carbonaria moths recaptured in the polluted woods.
			C)	There would have been many more typical moths recaptured in the unpolluted woods.
			D)	There would have been approximately equal numbers of carbonaria and typical moths recaptured in either woods.
