since there is no value assigned to variable e this seems to not work at all.
# Assume get_answer() is already defined
loop do
answer = get_answer()
if answer == e
break
end
end

Because at this line, you are comparing variable e to answer, but the variable e can't be found anywhere else in your program, it just pop up all the sudden at this line, so Ruby doesn't know what to do with it and gives you a syntax error.
either you define the e somewhere before that line, or perhaps if answer == 'e'.

14,329 Pointsnever mind.
I thought "Using a loop construct, assign the value of the get_answer() method to an answer variable. Use the break keyword to exit the loop if the answer variable is equal to the string e. Assume get_answer() is already written" meant answer variable == variable e.
Instead it was supposed to be a string consisting of a letter "e".
