Bart used to go to his health club every day after work because he almost always saw abigail there. for two full weeks abigail wasn't at the club when bart went there for his workout, and now bart has stopped going to his health club. this example illustrates the operant conditioning process ofa) resistanceb) avoidancec) punishmentd) extinction

d) extinction

Explanation:

Extinction: It refers to the process of disappearance or fading of a formerly learned behavior when that particular behavior is not being reinforced. The process of extinction is mostly associated with operant conditioning yet it can occur in various types of behavioral conditioning.

Example: A person has trained his cat to sit whenever he commands by associating it with giving a cat food (reinforcement), but when he stops giving the cat food when he commands to sit then overtime the cat might not respond to the command.

The given example in the question above illustrates the operant conditioning process of extinction.

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.

it should be d or b but i'm sure it's d
