From the viewpoint of the concept of the word "Housing", Does it include apartments?
Here is an example:
It's widely believed that housing in Boston is affordable; _____, one-bedroom apartments can cost up to $2,000 a month.
1) in contrast
2) on the contrary
3) in comparison
4) in addition
I'm sure the right answer is 2), because of "widely believed", semi-colon, and the conceptual range of housing that includes "apartments".
Is my answer and explanation correct?
