DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "PGchoicemacros.pl", ); TEXT(beginproblem()); |
Initialization: |
$mc = new_checkbox_multiple_choice();
$mc -> qa (
"Select all expressions that are equivalent to
\( e^{x^2 + 1/x} \). There may be more than
one correct answer.",
"\( e^{x^2} e^{1/x} \) $BR",
"\( e^{x^2} e^{x^{-1}} \) $BR",
);
$mc -> extra(
"\( \displaystyle \frac{ e^{x^2} }{ e^x } \) $BR",
);
$mc -> makeLast("None of the above");
|
Setup:
Use the question and answer method $mc->qa(
"Question text here.",
"\( x^2 \) $BR",
"\( \displaystyle \frac{x^2}{4-x} \) $BR"
);
Incorrect answers are specified as a list of string arguments to the
The arguments of the $mc->qa("question","None of the above");
$mc->extra("very wrong","distractor","red herring");
$mc->makeLast("None of the above");
To make answers appear in a certain order (e.g., Yes followed by No and Maybe), use |
Context()->texStrings;
BEGIN_TEXT
Additional instructions can be put here.
$BR
\{ $mc -> print_q() \}
$BR
\{ $mc -> print_a() \}
END_TEXT
Context()->normalStrings;
|
Main Text:
Print the question and answers. Print the question text using |
install_problem_grader(~~&std_problem_grader); $showPartialCorrectAnswers = 0; ANS( checkbox_cmp( $mc->correct_ans() ) ); |
Answer Evaluation: |
Context()->texStrings;
BEGIN_SOLUTION
${PAR}SOLUTION:$PAR
The correct answer is \{ $mc->correct_ans() \}
END_SOLUTION

COMMENT('MathObject version.');
ENDDOCUMENT();
