This is a question where students can choose only one correct answer
out of a selection. Each selection choice is called a foil because
the majority of the selection choices try to foil the student. Only
one foil is correct. LON-CAPA will randomly display the foils to your
students. If you choose to set the max number of displayed foils to
4 but only have 6 foils then LON-CAPA will choose one of the True
foils and fill in the rest of the foils with false foils up to a maximum
of four foils. To edit the 1 out of N multiple choice problem, enter
your question text into the appropriate box. Then enter one foil statement
in each foil box that you would like to use. You do not have to use
all 10 of the foil boxes. For each foil that you do use, you will
need to assign it a value of True or False. You can assign a foil
a location if you choose. For example, the foils will apear in random
order for your students. If you have a foil statement of {}``None
of the above'' then you will want this statement to always appear
at the bottom. After entering all of the correct foil text, you can
add an optional hint. The hint text will appear under your student's
view of the problem after getting one incorrect submission. The hint
text will remain displayed on your students view of the problem after
it is correct for study purposes. At any point in the editing process,
you can choose to store your changes. Each time you click \fbox{Store Changes}
, the current view of your problem will appear in box at the top of
the edit screen. When you are done editing, click the \fbox{Store Changes}
button and close the window by selecting the {}``x'' in the upper
right-hand corner of the window.
