Some people argue that the increased gap between rich and poor is caused (i)_____, which
tends to favor those who are already wealthy
Tends clearly refers to the gap , which is increasing over time. From this is logic to infer that is not the middle class that acts to increase the gap but is a phenomenon. Only B could explain this action. So for the first blank is B the answer. Turns out, this makes the world
divided into two main groups , so the answer is truncate which means just divide.
Polarized is exactly the contrary. Polarize means something the
concentrate rather than divide.
Hope now is more clear to you.
