Question $8$:

General performance elements of the Beatles include Paul McCartney...

sitting on a platform in the back while he happily smiles and shakes his head

looking ever calm while singing high notes and playing low notes

wind milling his right arm while jumping up and down, then doing the splits

on stage right, bobbing up and down with bent knees and looking down his nose

in the center of the stage, sharing a mic with Ringo

Question $9$:

New manager Brian Epstein insisted the group

while on stage.

continue to eat and smoke with their backs turned

wear their black leather outfits and boots

follow carefully choreographed dance steps

wear matching suits

all of the above
