Hilary's feeling of queasy at the sight of a brown paper bag is most clearly an example of classical conditioning.
Classical conditioning is a behavioral technique in which a biologically powerful stimulus (such food) is combined with a previously neutral stimulus. It is sometimes referred to as Pavlovian conditioning or responder conditioning (e.g. a bell). It also describes the process of learning that follows this pairing, in which the neutral stimulus eventually learns to elicit a response (such as salivation) that is typically similar to the one induced by the powerful stimulus.
Operant conditioning, often known as instrumental conditioning, is a type of conditioning in which the strength of a voluntary behavior is altered by rewarding or punishing it. Opportunistic responses may be reinforced by classically conditioned stimuli. However, classical conditioning can have a variety of effects on operant conditioning.
