Exercise 2.53.  What would the interpreter print in response to 
evaluating each of the following expressions?

(list 'a 'b 'c)

(list (list 'george))
(cdr '((x1 x2) (y1 y2)))

(cadr '((x1 x2) (y1 y2)))
(pair? (car '(a short list)))
(memq 'red '((red shoes) (blue socks)))

(memq 'red '(red shoes blue socks))

————————————————————————————————————————————————————————————————————————

(a b c)

((george))
((y1 y2))

(y1 y2)
false
false

true

(actually the last is wrong, should be (red shoes blue socks))
