What is the theory that professor hayes and dr. kim park are working on to predict when an earthquake is about to occur?

Explanation:

           Dr. Kim Parker and Professor Hayes are characters in the disastrous movie named, San Andreas. They are working with Caltech as seismologist. In the movie, they were able to make a breakthrough by developing way to predict earthquake using electro-magnetic pulses.

          Both the seismologist discovered such pulses in the Hoover Dam and went there to test their earthquake predicting model. They were correct in their prediction and the area was hit by a major earthquake of 7.1 Richter scale.

this question does't support enough resioning to answer.

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.
