我正在使用“文章”类输入如下的多项选择题：
在 Google 上快速搜索会返回与“考试”类相关的内容。我也尝试了\enumerate一下\itemize。我只得到以下内容
\documentclass{article}
\newcounter{choice}
\renewcommand\thechoice{\Alph{choice}}

\section*{No. 2-1}
\subsection*{Section A}
In humans, the pilomotor reflex leads to the response commonly known as goose bumps, and this response is widely considered to be vestigial—that is, something formerly having a greater physiological advantage than at present. It occurs when the
Line tiny muscle at the base of a hair follicle contracts, pulling the hair upright. In animals with feathers, fur, or quills, this creates a layer of insulating warm air or a reason for predators to think twice before attacking. But human hair is too puny to serve these
functions. Goose bumps in humans may, however, have acquired a new role. Like flushing—another thermoregulatory (heat-regulating) mechanism—goose bumps have become linked with emotional responses, notably fear, rage, or the pleasure of, say,
listening to beautiful music. They may thus serve as a signal to others.
