City planners often build transportation systems to accommodate geographic characteristics.

True

Explanation:

It is true that city planners often build transportation systems to accommodate geographic characteristics. City planners tend to accommodate geographic characteristics because this is a cheaper, more efficient and more aesthetically-pleasing approach. When city planners act in this way, they are responding to the demands of land, and taking into account the distribution of water, the quality of the soil, the elevation of the terrain, etc.

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.  

well this isn't a question but if you are asking if it is true or false it is, true.
