Необычное поведение multicols в enumerate при использовании forloop для указания количества элементов

Question

Я использую examкласс документа и заметил необычное поведение разрывов столбцов в среде перечисления при использовании a forloopдля указания количества элементов.

Когда я использую forloop для генерации пронумерованного списка строк ответа, я получаю следующее:

Однако когда я вручную генерирую пронумерованный список, я получаю следующее:

Вот мой MWE, который дал оба результата:

Answer 1

«MWE» довольно трудно читать, но основные проблемы таковы:

• \begin{enumerate}\begin{multicols}{4}выглядит неправильно → используйте наоборот
• Инициализируется \forloopс помощью \ref{firstA}, который не расширяется или предоставляет что-то, не являющееся действительным (целым) числом. Этот цикл испорчен. Чтобы получить значение счетчика ссылок, используйте \getrefnumber{firstA}, загрузив пакет refcount, конечно, для этого Использование \ref{firstA}этого запутает команду, оставив мусор в списке перечисления и также \forloopзапутав .multicols
• Начальное значение enumerateдолжно быть задано с помощью enumitemпакета и его start=опции enumerateвместо \setcounter{enumi}{...}(я этого здесь не делал!)
