Hi Jerry,
 Welcome to the newsgroup / list.

to display the shapes at random,

setsh textpick "text1

or, you could do the whole thing on procedure page:-

to animals
setsh pick [horse1 dog1 bee1]
end

However, once you display them randomly then you need to store the value so 
that you can later check whether the guess is correct:-

to animal
local "choice
make "choice textpick "text1
setsh :choice
question [what animal?]
ifelse equal? answer :choice [announce[correct]][announce[badluck]]
end

Notes:-
You would have to rename your animals from horse1 to horse, etc.
Move turtle away from centre so pop up question box does not hide it
local keeps the variable local (works without it but bad style)
:choice extracts the particular animal value from the variable choice
other primitives, refer to online help.
