Hi Sally,

This will work:

<problem>
<script type="loncapa/perl">
 $graph[0]=
    &xmlparse('<gnuplot><curve><function>sin(x)</function></curve></gnuplot>');
 $graph[1]=
    &xmlparse('<gnuplot><curve><function>cos(x)</function></curve></gnuplot>');
 $graph[2]=
    &xmlparse('<gnuplot><curve><function>tan(x)</function></curve></gnuplot>');
 $graph[3]=
   &xmlparse('<gnuplot><curve><function>asin(x)</function></curve></gnuplot>');

 @foils=('Sin(x)','Cos(x)','Tan(x)','Asin(x)');

 $seed=&random(1,1000000,1);
 @foils=&random_permutation($seed,@foils);
 @graph=&random_permutation($seed,@graph);
</script>

<startouttext />
<table>
<tr>
   <td>A</td><td><display>$graph[0]</display></td>
   <td>B</td><td><display>$graph[1]</display></td>
   <td>C</td><td><display>$graph[2]</display></td>
   <td>D</td><td><display>$graph[3]</display></td>
</tr>
</table>
<endouttext />

<optionresponse max="10" randomize="yes" TeXlayout="horizontal">
  <foilgroup options="('A','B','C','D')">
    <foil location="random" value="A" name="foil1">$foils[0]</foil>
    <foil location="random" value="B" name="foil2">$foils[1]</foil>
    <foil location="random" value="C" name="foil3">$foils[2]</foil>
    <foil location="random" value="D" name="foil4">$foils[3]</foil>
  </foilgroup>
</optionresponse>

</problem>
