Hydrogen fuel cell use as a form of energy - is accessible in limited parts of the world due to the need of hot spots

- produces heat for energy, but requires pipes to be laid in the ground

- has low environmental impact if produced from water

- can be expensive and can leak radiation

i am confused on the question.

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
