I wonder who decides what sort of 1) ... animals... (animal) are kept in 2) (zoo)? You expect to see a lot of 3) (monkey), 4) (rhino), and 5) (lion), but you rarely see 6) (ox), 7) sheep), 8) (deer) or 9) (goose), probably because these can be seen commonly enough in the wild.Each day large 10) (delivery) of food arrive for the 11) (beast) to eat. Not expensive items like 12) (salmon) or 13) (trout), but ordinary things like 14) (potato) and 15) (tomato) ;. although the 16) (panda) like 17) (bamboo). Tne whole family, 18) (man), 19) (woman) and 20) (child) can take 21) (photo) or make 22) (video) of them eating with their 23) (paw) and 24) (tooth), since animals do not use 25) (knife) and 26) (fork) to eat.
