S: Our nation is becoming too averse to risk. We boycott any food reported to contain a toxic chemical, even though the risk, as a mathematical ratio, might be minimal. With this mentality, Columbus would never have sailed west.
T: A risk-taker in one context can be risk-averse in another: the same person can drive recklessly, but refuse to eat food not grown organically.
T responds to S by showing that:
(A) a
distinction should be made between avoidable and unavoidable risks - WRONG. No comparison as such is suggested.
(B) aversion to risk cannot be
reliably assessed without reference to context - CORRECT. If context is there then risk aversion is subjective.
(C) there is
confusion about risk in the minds of many members of the public - WRONG. Irrelevant.
(D) mathematical odds concerning risk give an
unwarranted impression of precision - WRONG. It's not about the precision of the risk but why S said so can be analogised in similar ways in different scenarios.
(E) risk cannot be defined in relation to
perceived probable benefit - WRONG. 'Benefit' is a diversion from the scope of the passage.
Answer B.
