What is the problem with the employee of the fast food restaurant?
A. She does not know how to operate the cash register.
B. She is unable to solve simple math problems.
C. She lacks coins for customers' change.
D. She does not know how to count coins
题目解答
答案
B. She is unable to solve simple math problems.
解析
本题考查对对话内容的理解，关键点在于识别员工在处理找零问题时的核心困难。题目中员工因现金出纳机故障无法正确找零，但问题本质并非操作机器或缺乏零钱，而是无法准确进行简单数学计算。因此需抓住对话中隐含的逻辑关系，排除干扰项。
选项分析
选项A：She does not know how to operate the cash register.
- 错误原因：题目中现金出纳机已明确出现故障（"the cash register is broken"），问题并非员工不会操作机器，而是无法手动计算找零。
选项B：She is unable to solve simple math problems.
- 正确原因：对话中员工无法正确计算找零（如将$5$美元找零错误计算为$3$美元），直接说明其数学计算能力不足。
选项C：She lacks coins for customers' change.
- 错误原因：员工表示"we don’t have enough coins"是借口，实际问题在于计算错误，而非真正缺少零钱。
选项D：She does not know how to count coins.
- 错误原因：数硬币（count coins）是基础操作，而题目核心是数学计算（如减法运算），D项描述范围过窄。
