Dr. Moore and his team have learned from GPS data that two continents with an ocean between them have been moving toward each other. Some students living on the coast of one of these continents don't understand what is happening and they are worried that the continents will run into each other. How could Dr. Moore explain to them what is happening?

Dr. Moore can explain that this is a continental drift process and that it is an extremely slow process and therefore no one should be concerned.

Explanation:

Continental drift is a geographic phenomenon that allows continents to move and "walk" towards each other. It is true that this can make the continents shock and cause a great catastrophe that would make human life rich, but there is no need to worry. This is because this movement is extremely slow and would take thousands of years for the continents to collide.

even though you have attached neither the chart nor the generalizations, i have located them online. the right answer is d, since they are asking you about a generalization. you can only infer from the chart that between 2008 and 2009 the number of employed workers decreased significantly (from over 115 millions to 107 millions approximately), which signals some type of economic crisis.
