What culture will heavily influence early Islamic culture, due to its classical influence?

Because Islam originated and has developed in an Arab culture, other cultures which have adopted Islam have tended to be influenced by Arab customs. Thus Arab Muslim societies and other Muslims have cultural affinities, though every society has preserved its distinguishing characteristics.  

hope this helped

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.  

what is the question?
