Itay,
I took a look at the source code for chipmunk_velocity.problem, as it's
published with source XML open.
If you retain only the first opening foilgroup tag: <foilgroup
options="('True','False')"> (i.e., the one after the opening optionresponse
tag), and retain only the last closing foilgroup tag:</foilgroup> (i.e., the
one before the closing optionresponse tag), but remove the other <foilgroup>
</foilgroup> tags (wrapped around each <foil> </foil>, then submissions are
graded as expected.

Subject: [LON-CAPA-users] Unexpected behavior of an optionresponse problem
Hello Lon-Capa community
I encountered an optionresponse problem in which lon-capa rejects its own
answers... :-(
I copied the source code of the following problem to my author space:
/res/ohiou/physicslib/exam/05_1D_Motion/chipmunk_velocity.problem
Then, still in author space, I tested several randomizations, with the same
outcome each time: lon-capa has rejected my submission although it fully agreed
with the answers provided by lon-capa (at the bottom of the problem's screen).
Note, that these answers agreed with my independent conclusions as well.
It is probably something silly that I have missed... but what it is I cannot
tell.
Or is it a bug?
Thanks,
Itay
