After an oil spill, rehabilitation centers were set up to save sea otters by removing oil from them. The effort was not worthwhile, however, since 357 affected live otters and 900 that had died were counted, but only 222 affected otters, or 18 percent of those counted, were successfully rehabilitated and survived. Further, the percentage of all those affected that were successfully rehabilitated was much lower still, because only a fifth of the otters that died immediately were ever found.

Which one of the following, as potential challenges, most seriously calls into question evidence offered in support of the conclusion above?

(A) Do sea otters of species other than those represented among the otters counted exist in areas that were not affected by the oil spill?

(B) How is it possible to estimate, of the sea otters that died, how many were not found?

(C) Did the process of capturing sea otters unavoidably involve trapping and releasing some otters that were not affected by the spill?

(D) Were other species of wildlife besides sea otters negatively affected by the oil spill?

(E) What was the eventual cost, per otter rehabilitated, of the rehabilitation operation?

Eventually guessed the correct option B by POE, but took 4 mins. Didn't understand a bit of the stimuli.
Waiting for experts opinion.

The author mentions the situation in which "After an oil spill,rehabilitation centers were set up to save sea otters by removing oil from them."
The conclusion that the author cites here is "The effort was not worthwhile"
The evidence that the author provides to support his conclusion is:
1. 357 affected live otters and 900 that had died were counted.
2. Only 222 affected otters, or 18 percent of those counted, were successfully rehabilitated and survived.
3. The percentage of all those affected that were successfully rehabilitated was much lower still, because only a fifth of the otters that died immediately were ever found.

Which of the answer options most seriously calls into questions the evidence offered - only a fifth of the otters that died immediately were ever found.
Quote:
(A) Do sea otters of species other than those represented among the otters counted exist in areas that were not affected by the oil spill?

Author here isn't really concerned about these 2 things mentioned in the answer option here:
1. species other than those represented among the otters
2. areas that were not affected by the oil spill
The author here wants to weaken the evidence offered in support of the conclusion.
Quote:
(B) How is it possible to estimate, of the sea otters that died, how many were not found?

This options seem legitimate. This option poses question on the possibility of counting/estimation of the sea otters who were not found.
hence calling into question the evidence provided to support the conclusion.
We may keep this option on hold.
Quote:
(C) Did the process of capturing sea otters unavoidably involve trapping and releasing some otters that were not affected by the spill?

What did the rehabilitation process involve, isn't much of a concern here.
Quote:
(D) Were other species of wildlife besides sea otters negatively affected by the oil spill?

Other Species of wildlife. I don't know why have these been mentioned here.
Quote:
(E) What was the eventual cost, per otter rehabilitated, of the rehabilitation operation?

Cost is of no concern to the stimulus.

hence B is best option.
