Acquisition merger what is the point?

Amazon bought Whole Foods in a merger/acquisition. Do you think this was a acquisition of scale or scope? 

What are the difference between the two? 

How can both scale and scope benefit both companies? 

What immediate gains scale or scope occurred during/after the merger? 

What did Whole foods gain in terms of growth? 

Will whole foods see long term higher profit expectantly?

Make a case for whether or not Amazons merger/acquisition was mostly about gaining economies of scale or economies scope?
