Fleurette is conducting a comparative investigation where she is comparing the average acceleration of two different types of cars. She collects data and comes up with a conclusion. What is a major limitation of her experiment?
A. Large amounts of information can be gathered.
B. The investigation is not repeatable.
C. She cannot explain what causes the difference.
D. There is an independent variable and a dependent variable.
I think the major limitation of her experiment is : C. She cannot explain what causes the difference To find this out, she need to find out which could be the independent variable (such as the machine, tire, wind, etc)
