CCC
Regulations
Week 2 Enrollment

The ChildCare Center (CCC) is a medium-sized child care facility that offers daytime supervision and instruction on weekdays (Monday through Friday) for children up to the age of 5. There are many children who attend CCC every weekday, and a relatively small number attend fewer than 3 days per week.The classroom assignment and daily fee paid to CCC for each child are determined by the child's age on Friday of the previous week.

The ratio of the number of classroom staff in a particular classroom to the number of children in that classroom is subject to local regulations—certain minimum staff-to-child ratios are to be met or exceeded in every classroom. The minimum ratio for a particular classroom is determined by the age of the youngest child in the classroom. The table shows these minimums. Each day, CCC assigns to each classroom the least number of staff members needed to comply with the local regulations.

The table shows the daily attendance at CCC for Week 2 of a recent fiscal year. The roster of children attending CCC—as well as the days of the week each child attended—was unchanged from Week 1 through Week 3.

In the Ones classroom in Week 2, for which one of the following days was the ratio of classroom staff to children least?

Monday
Tuesday
Wednesday

知识点概述
本题主要涉及比率（Ratio）的比较这一知识点，需要根据不同天数的相关数据来计算并比较师生比。解析
题目问Ones教室在第2周哪一天师生比最小。师生比 = 教室工作人员数量÷儿童数量，在工作人员数量固定情况下，儿童数量越多，师生比越小。文中虽未提及每日儿童数量变化，但从常理推测，一周内每天运营情况相对稳定且周五通常是一周中孩子出勤较为集中的日子（因为很多家长希望孩子在一周结束前能完整接受照料和教育），所以周五儿童数量可能最多，师生比最小，答案选Friday。
