<u>Answer</u>: a. This represents the requirements for the highest quality scientific methodology.
This question is part of the problem solving value rubric created by the AACU (The Association of American College and Universities). The number 4 represents the score assigned to the experimental design and the text illustrates the requirements needed to reach it.
a - is the highest score - the capstone
b&c - the milestones
d - the benchmark - the minimum score needed to pass.
Anything lower than the benchmark will be assigned a 0 and failed.
