Answer:

A.

No; Harriet should race the animals several times before she makes that conclusion.

Explanation:

When you make a conclusion, you have to consider that your data can come out differently each time. After you race them about 5 times or so, collect the data and find the average time of each one, then you will get a basic idea of which one is faster.
