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.

Suppose that, in an effort to reduce staffing costs for the Friday of Week 2, the director of CCC had considered combining some classes for that day. For each of the following combinations, select Decrease if combining those classes would have decreased the number of classroom staff needed, provided that no other changes had occurred. Otherwise, select Increase/no change.

知识点概述
本题主要涉及逻辑推理中的条件判断，根据班级合并这一条件，判断对教室工作人员数量的影响。解析
- Infant/Ones：将Infant（小于1岁）和Ones（1岁）班级合并，原本两个班级需要两套工作人员，合并后只需一套，会减少所需的教室工作人员数量，选Decrease。 - Ones/Twos：Ones（1岁）和Twos（2岁）班级合并，同样原本两个班级对应两套工作人员，合并后一套即可，会减少所需的教室工作人员数量，选Decrease。
