在 \task 环境中，现在要关闭单行文本的枚举吗？

修改 OP 代码以插入\task*强制在任务环境中向左对齐的一行文本。（h/t @JohnKormylo）

但我需要关闭下面两行文本的枚举：

（注：此测试键有几个部分不是按顺序编号。这就是为什么我没有将它们创建为正式的副标题。一个失误？）

另一个问题关于解决方案步骤之间的行距。使用\bigskip（定义）是否是\def\bigskip{\vskip\bigskipamount}创建垂直空间以增强各个解决方案步骤的可读性的最有效方法？

非常感谢您花时间审阅/回复这篇文章。

请注意，这\fullwidth是关于缩进，而不是列。 \globalcounter*防止每列有单独的问题编号。 \switcholumn*对齐下一组列的顶部。
