Editorial: The gates at most railroad crossings, while they give clear warning of oncoming trains, are not large enough to prevent automobile drivers from going around them onto the tracks. Some people claim that the ensuing accidents are partly the fault of the railroad company, but this is a mistake. Granted, if one has a small child in the house, then one ought to block access to stairs completely; but a licensed driver is a capable adult who should know better.
The editorial's conclusion follows logically if which one of the following is assumed?The editorial concludes that railroad companies are not partly responsible when licensed drivers ignore the gates and drive onto the tracks.
The missing link is that
a capable adult who disregards an adequate warning is fully responsible for the resulting accident.
(A) The gates could be made larger, yet irresponsible drivers might still be able to go around them onto the tracks.
Incorrect. This does not establish that the railroad company bears no responsibility for the accidents.
(B) Capable adults have a responsibility to take some measures to ensure their own safety.
Incorrect. Having some responsibility does not mean they have full responsibility. The railroad company could still be partly responsible.
(C) When the warnings of companies are disregarded by capable adults, the adults are fully responsible for any resulting accidents.
Correct. This directly connects the fact that licensed drivers are capable adults who disregard a clear warning to the conclusion that the railroad company is not partly responsible.
(D) Small children are not involved in accidents resulting from drivers going around the gates.
Incorrect. The reference to small children is only an analogy. Whether children are actually involved in these accidents is irrelevant.
(E) Any company's responsibility to promote public safety is not unlimited.
Incorrect. This only says that companies have some limit to their responsibility. It does not establish that the railroad company's responsibility ends in this particular situation.
Answer: (C)
