PROBLEM: Question: If Mona's country normally emits a lot of greenhouse gas, but one day decides to lower the amount they emit, what will happen to the global temperature?

PROBLEM: Question: 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 
 Option1: alkane with fewer carbon atoms 
 Option2: alkane with more carbon atoms? 
 Explanation: Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.

SOLUTION:
alkane with fewer carbon atoms
