Jamal is coming up against George Miller's magic number 7, plus or minus 2.

Explanation:

It was George Miller who first produced the idea that our short term memory is capable of holding from 5 to 9 items (that's why 7 plus or minus 2). According to Miller, short term memory has a limited capacity of around 7 slots, each capable of holding a "chunk" of information. It also has a very limited duration - from 15 to 30 seconds only. When Jamal tries to repeat all the numbers of his credit card, he is coming up against this magic number of around 7 slots.

answer; /// i believe the correct answer is (when one group has an extremely high score at pretest;

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.
