I think so. You want the data file to look like this:

{"How old are you?", "What time of day is it?"}
{"37", "2:00pm"}

Correct? If so, the code should look something like this.

--==[Untested code!]==--
include get.e

sequence question, answer
integer fn

-- Open the file (assume success in this code snippit. NEVER assume
-- this in the actual code
fn = open("data.dat", "r")

-- Get the questions
question = get(fn)
if question[1] = GET_SUCCESS then
    question = question[2]
end if

-- Get the answers, if present.
answer = get(fn)
if answer[1] = GET_SUCCESS then
    answer = answer[2]
    puts(1, "\nThe questions have been answered.\n")
else
    answer = repeat("", length(question))
    puts(1, "\nThe questions have not been answered.\n")
end if

close(fn)

-- Do code for getting the answers and questions and such.
for i = 1 to length(question)
    puts(1, question[i] & " ")
    answer[i] = gets(0)
    answer[i] = answer[i][1..length(answer[i])-1]  -- Strip off \n
    puts(1, "\n\n")
end for

-- Place data into file (Assumes success in opening file)
-- This method won't be easy to read, though.
open("data.dat", "w")
print(fn, question)
print(fn, answer)
-- end untested code

If you need to be able to read the data file, then I can give a way to do
that also.
If this isn't close enough to what you need, tell me what is off so I can
fix it. :)
