Agroup of students run a simulation of resource consumption in which cereal is used to model a resource. the students use tweezers to pick up pieces of cereal one at a time and place them in a cup. the group runs the simulation two times, keeping all factors the same except the number of students allowed to collect the cereal at the same time. what variable are the students most likely testing?

a. conservation method

b. use of technology

c. population size

d. evenness of distribution

Answer: C. Population size

The students are trying to simulate the effects on a food resource which different population sizes may have. Each number of students per week represent different population sizes.

C. Population size

Explanation:

Because it is mentioned that all factors were kept the same, except for "number of students allowed to collect cereal at the same time" and this represents a change in the number of members in a population, which determines the size of the popuation itself.
