Subject: Re: variable from array to function to array

The bigger picture...  I am saving multiple question templates in a 
array and need to store all the info (the question, the min and max 
ranges, the units of measure etc assoc with each question.  The 
associated info is used to build the question ... eg in question one, 
need to pass 20,40 to number_range(min,max)  and use the returned value 
as u.

def number_range(min,max)
  min + rand(max - min + 1)  **Thanks!
end

array =[
[ lambda {|u,u_unit| "A slide is placed #{u} #{u_unit} to the left of a 
lens...", 20, 40, "cm"],
[ lambda {|v,v_unit| "An image is in focus #{v} #{v_unit} to the right 
of a...", 10, 25, "mm],
[....
]


puts array[n][variable returned from number_range method]


>>  A slide is placed 25 cm...


Also,
def random_age_string(range)
   "A #{rand(range)} year old"
end

puts random_age_string(20..40)

Does not work as I am not able to embed "#{}" in a string in an array... 
it just returns the string without evaluating...
