Thanks for posting the answers!
The few that I got different were-
5) C - As new semantic memories are formed in the Hippocampus I assumed there would be an increase in neurons there (however since it's adaptive plasticity there may not actually have been an increase in neurons just synapses, not sure...)
20) A- I thought this was a little bit ambiguous if it was cerebral cortex or frontal lobe as that's involved in planning, reasoning and imagining
24) B- But I see you changed it
35) B- Body temperature doesn't reach its lowest in REM sleep, it is lowest during deep NREM and actually increases in REM
52) C- Since the question is talking about the physical capacity to reproduce the behaviour (not his motivation to do so) I assumed it was about being taught to knit
