In Scheme, a list is a pair, containing the head/car (first element of 
the list) and tail/cdr (sublist of all other elements). A list 
containing only one element is a pair of that element and an empty list '().

'(1 2 3 4 5)
is the same as
'(1 . (2 . (3 . (4 . (5 . ()))))

So the car of the list above is 1, the cdr is '(2 3 4 5). If you want to 
get the 2, you have to take the car of '(2 3 4 5). And cadr is short for 
“car of cdr”.
