This is a somewhat more difficult version of a Venn Diagram question. The question refers to Book Smart employees and Street Smart employees. It's best to know which portion of the diagram refers to which type of empoyees so you can better understand the questions.
The questions refer to Book Smart employees and ask you to compare them to the Street Smart employees. Which side has more and which side has less? What portion of them have college degrees and what portion of them do not?
These are good exercise questions to ask yourself so you can get more comfortable navigating around these venn diagrams.
Lastly, notice that the second question includes these potential answer choices:
1) True 2) False 3) Not Enough Information
Doesn't this sound similar to data sufficiency? There are also elements of this kind of "sufficiency" in certain types of Two-Part Analysis questions. Here, the element of sufficiency appears in graphical interpretation questions in the form of a true or false question. Do you have enough information to answer #2 definitively as a true or as a false? Or is there not enough information? That's your job.
