An educational researcher wanted to test the impact of learning environment on children's ability to concentrate on a short reading comprehension task. There were four different environmental settings: 'Noisy', 'Chill Out', 'Cold', and 'Screen on' and a group of twenty randomly selected children. He wanted to compare the impact of each setting on each child's individual concertation times and across the group, as well as any interaction effects. What sort of test design best suits this study?
A)Repeated-measures factorial design
B)Independent factorial design
C)ANOVA
D)Multiple linear regression.

A repeated-measures factorial design would be the most appropriate for this study as it allows for each child's concentration times to be measured in each of the four environmental settings. It also allows for the examination of interaction effects between the environmental settings.
