Once again a poorly worded question.
Choice E should have been better worded.
It should have said Children used to supplement their parents income but no longer have to do so.
If the parents were that bad off before, the children can only afford so much.
Who is to say that even with the increase in pension and their supplementary funds that the parents are living comfortably?
I was told never to read into or assume any information, and that seems like what is happening with alot of questions on this board.
