Multiple choice quiz graying out incorrect answers until correct chosen

[ben robinson]

i don't fully understand what you are asking, but one simple method for
using information from one experiment in another that i've used myself is to
have your first experiment create a text file and write, say, your accuracy
score into the text file.  save the text file with the subject number in the
filename, use the same subject number in your next experiment, and have that
next experiment look for a text file with the appropriate filename.  open
the text file, read the accuracy, and viola, you have the information from a
previous experiment available to you in your next experiment.
