b several behaviors can be chained together through operant or classical conditioning.
c reinforcement or punishment can include other activities as well as tangible objects.
d if somebody wants to artificially create a taste aversion by poisoning an undesired food, it is less effective if the subject knows there is medicine in his

Explanation:

To determine the best evidence for cognitive factors in learning, we analyze each option:

• Option A: Focuses on reinforcement schedules' effectiveness, related to behavioral (not cognitive) factors.
• Option B: Discusses chaining behaviors via conditioning, which is behavioral conditioning, not cognitive.
• Option C: Describes types of reinforcement/punishment, still behavioral.
• Option D: States that knowing about medicine (a cognitive factor) reduces the effectiveness of taste aversion conditioning. This shows cognition (knowledge) impacts learning, so it's the best evidence for cognitive factors.

Answer:

D. If somebody wants to artificially create a taste aversion by poisoning an undesired food, it is less effective if the subject knows there is medicine in his
