### Re: Why quoted text removed from answer displays by Webwork? (Still graded right.)

Is there any way to set a string to display as the answer when students select "Show correct answers" ?

Sure. Whatever you put in the quotations for Compute will be the correct answer. So

    $strings = Compute($string_answers[0])->cmp(checker => sub {...});

would do it.

On the other hand, I think this this type of answer checker is a bad idea, as they give no useful feedback when students are wrong (e.g., due to a spelling error). Unless their knowledge of the existence of the word "scalene" is what you are trying to test, I would rather see a pop-up menu with "Equilateral", "Isosceles", and "Scalene".

Alternatively, you could use the contextString.plfile and the String context to get better results. Here is an example:


DOCUMENT();

"PGstandard.pl",
"MathObjects.pl",
"contextString.pl",
"PGML.pl",
);

TEXT(beginproblem());

Context("String");
Equilateral => {},
Isosceles => {},
Scalene => {},
"Equilateral triangle" => {alias => "Equaliateral"},
"Isosceles triangle" => {alias => "Isosceles"},
"Scalene triangle" => {alias => "Scalene"},
);

$ans = "Scalene"; BEGIN_PGML [$ans] = [____________]{\$ans}
END_PGML

ENDDOCUMENT();

This gives better error messages. See if that works better for you.
