Final Answer : C, Explanation :  The fact that Francesca was allowed to use a graphing calculator while her sister was not suggests that the test has undergone changes over time. This means that it would be difficult to meaningfully compare the scores of the two sisters since they took versions of the test with different rules and requirements. It is important to note that this does not necessarily mean that one sister scored higher or lower than the other, but rather that their scores cannot be compared with confidence.
