Question ID:PT27 S1 Q3 Passage:     In Yasukawa's month-long study of blackbirds, the percentage of smaller birds that survived the duration of the study exceeded the percentage of larger birds that survived.  However, Yasukawa's conclusion that size is a determinant of a blackbird's chances of survival over a month-long period is probably mistaken, since smaller blackbirds are generally younger than larger ones. Stem:The statements above, if true, support which one of the following inferences? Correct Answer Choice:DChoice A:Among the blackbirds that survived the month-long study, there was no relation between size and age. Choice B:Larger blackbirds of a given age are actually more likely to survive over a one-month period than are smaller blackbirds of the same age. Choice C:Among blackbirds of the same size, a difference in age probably does not indicate a difference in chances of survival over a one-month period. Choice D:Among blackbirds of the same age, a difference in size may not indicate a difference in chances of survival over a month-long period. Choice E:With a larger sample of blackbirds, the percentage of smaller birds that survive a one-month period would be the same as the percentage of larger birds that survive.
