Given the question: Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.  Kathy did some experiments on two different alkanes and one of the alkanes had twice as many carbon atoms than the other. She would notice that which alkane would require a lower temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms??
The answer is:
alkane with fewer carbon atoms
