Reading the argument
The safer nursery isn't necessarily the better preparation for life in the wild.
Trained humans expose the chicks to less risk of injury than adult condors do. That is a real advantage. But these chicks aren't being raised to remain protected in captivity forever. The passage says that chicks reared by condors ultimately have a better survival rate after release.
I can imagine why learning from their own species might matter. Perhaps human-reared birds become too comfortable around people or miss skills they would acquire from adult condors. Those are possible explanations, not facts we need to import. The stated comparison already tells us that the increased injury risk comes with a larger survival benefit.
What we’re looking for
For the most-supported answer, keep that trade-off intact: exposure to adult condors is more valuable for preparing these chicks for the wild than shielding them from every risk those adults pose. We don't need to pretend the risk disappears in order to recognize the overall advantage.
Working the answers
- A
This compares how easy two goals are to achieve: survival in the wild and reduced injury risk in captivity. The passage doesn't measure the difficulty of either task. It compares two rearing approaches and says which produces the better eventual outcome. A difficult goal might still be worth pursuing, and an easy goal might still be less important to that outcome.
- B
Both groups in the passage consist of chicks born in captivity. They differ in who raises them. We aren't comparing captive-born birds with wild-born birds, so we can't infer that either captive-born group's survival exceeds the rate among birds born in the wild.
- C
The passage doesn't compare the parenting techniques of adults raised in the wild with those of adults raised in captivity. It compares rearing by condors with rearing by humans. The adult birds could differ in their techniques without changing the particular advantage the passage reports.
- DCorrect
Exposure to adult condors matters more for the chicks' development of survival skills than protection from those adults does. The passage acknowledges greater injury risk but still favors condor rearing because of the later survival advantage. D captures that balance. It doesn't claim injuries are harmless or identify the exact lessons the chicks learn; it identifies which consideration has greater importance for preparing them to survive outside captivity.
- E
A higher survival rate doesn't tell us the absolute rate. The comparison could be 80 percent versus 60 percent, or 10 percent versus 5 percent. Both would make one approach better, but only the latter would suggest survival is unusual in both groups. Those are illustrations of the missing information, not reported statistics. We cannot infer “only rarely” from a relative improvement.
