Choosing the statement that Harriet runs faster than Emma does not necessarily follow from the information given about Harriet and Andrea. The initial statement only establishes a relationship between Harriet and Andrea's speeds, without mentioning any information about Emma's running speed in relation to either Harriet or Andrea.

For the valid interpretation, if Harriet is faster than Andrea, it does not imply anything about her relative speed compared to Emma. Thus, one cannot conclude with certainty that Harriet also runs faster than Emma. For the other statements, they similarly do not follow from the relationship stated in the question. The lack of correlation between Harriet’s and Emma's running speeds means that none of these statements must be true based solely on the information provided.

In this instance, the correct answer hinges on the logic that there is no definitive connection established between the speeds of Harriet and Emma, maintaining that knowledge of one does not necessitate knowledge of the other.
