; ★ Question #1. Write out the following steps. ★
; Start by under-lining which part(s) of the stepped expression will change, rather than copying the expression just to under-line part of it. Omit “! Steps !” , “○” , and “•” .
(step (map function? (list “ant” #true list flip
(step (map text? (list text-length “ant” scale
(step (map list? (list “ant” list #false – 25)))
(step (map unary? (list list? list length inc)))
(step (map binary? (list list? list length inc)))
(step (map triangle (list 20 25 10)))
(step (combine filled-oval (list 25 10)))
(step (map list (list “ant” #true list flip )))
(step (combine list (list text-length “ant” scale
)))
25)))
25)))

(step (map thinner (list )))
(step (combine align-lefts (map mirror (list ))))
(step (map + (list 20 25 10)))
(step (combine + (list 20 25 10)))
(step (map * (list 20 25 10)))
(step (combine * (list 20 25 10)))
(step (map – (list 20 25 10)))
(step (combine – (list 25 10)))
(step (combine / (list 20 10)))
(step (map dec (list 20 25 10)))

; ★ Question #2. Assume the following definitions have been entered/run … (define s (filled-square 10))
(define c (circle 16))
(define r (combine rectangle (list 30 10))) (define l (list s c r))
; … then write out the following steps (in the same manner as in Question #1) …
(step (list s c r))
(step (map filled-circle (map height (map shorter l))))
(step (combine above (map text->image (map text-join (list “ant” “bear” “ox”)))))
(step (above (text->image (combine text-join (list “ant” “bear” “ox”)))))
(step (combine beside (map taller (map square (map inc (map text-length (list “ant” “bear” “ox”)))))))
