Unplugged Practice Test: Logical Reasoning Set 2, Question 23 (Principle)

Nursery consultant: Orchid growers whose greenhouses run automatic misting systems correctly believe that their plants are at little risk of drying out, and so they test the moisture of the bark medium less often than they would if they watered by hand. It follows that if a spray were introduced that reliably cured the fungal infections that attack orchid leaves, growers would probably grow lax about crowding plants on the benches and leaving water standing on the foliage, 2 practices known to invite those infections.

23. The nursery consultant's reasoning most closely conforms to which one of the following principles?

1. (A)People who are aware of more than one precaution against a particular danger tend to adopt only the precaution they think most effective.
2. (B)People go out of their way to avoid conduct they expect to cause them serious harm, and make no such effort with conduct they expect to be entirely harmless.
3. (C)People act more cautiously in undertakings whose hazards they understand than in undertakings whose hazards remain unknown.
4. (D)When a means is found of sparing people the usual consequences of a harmful practice, they often become less careful about avoiding that practice.
5. (E)People put great weight on escaping severe harm to themselves, yet their various desires frequently override their concern with minor harm.
