Patricia, a 14-year-old girl, has not been doing her math homework. consequently, she failed her math exam. her parents have decided to place her on restriction, so she is not allowed to talk on the phone after school for two weeks. if placing patricia on restriction serves to decrease the number of failing math grades that she receives, then the restriction was an effective form of
a) punishment. b) classical conditioning. c) social learning. d) reinforcement

The restriction was an effective form of A. Punishment.

Explanation:

Skinner's operant conditioning refers to the fortification of a behavior by reinforcements and punishments. Patricia receives a negative punishment in which a stimuli she likes (the phone) is taken away from her in order to decrease her grading fails.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
