`text`	`character` vector with the prompt for the problem.
`answers`	A `list` of `problem` or `problemset` objects.
`correct`	Indices of answers which are correct.
`first`	Number of observations at the beginning of `answers` which will not be shuffled.
`last`	Number of observations at the end of `answers` which will not be shuffled.
`solution`	Text for the solution to the problem.
`randomizable`	Can the answers be shuffled?
`x`	The object
`shuffle_answers`	Shuffle answers?
`show_solutions`	Display the solutions to the answers?
`tpl_problem`	Whisker template to use when rendering the object.
`tpl_answerlist`	The template to use to render the object.
`counter`	A counter to keep track of the number of problems.
`cnt_problem_1`	A counter for the top level `problem` and `problemset` objects.
`cnt_problem_2`	`NULL` if the problem is not in a `problemblock`. Otherwise, the number within that `problemblock`.
`format_cnt_problem_0`	A function used to format `cnt_problem_0`.
`format_cnt_problem_1`	A function used to format `cnt_problem_1`.
`format_cnt_problem_2`	A function used to format `cnt_problem_2`.
`.debug`	Useful for debugging. Shows the data that is passed to the template.
`...`	Used by the template and passed to `format.answerlist`.
