Argh...Sorry, wrong key too early...here's the full changes:

rule "Combine ODMAnswers"

when

$list : List( )
$a1:ODMAnswer( some check ) from $list

$a2:ODMAnswer( assuming something making this one different than $a1 ) from $list

then
$list.add(new ODMAnswer( ));
$list.remove($a1);
$list.remove($a2);
end
