This is our 法律常识 quiz

This is our 法律常识 quiz. I am answering based on the law of the 90's of China

The first man's asset is (1/2 of house), when he dies
"A" should own: (1/2 of house) +
1/2 * (1/2 of the house owned by the first man)
=3/4 of the house
x should own 1/2 * (1/2 of the house owned by the first man)
= 1/4 of the house

Now after A dies, her asset = 3/4 of the house is subject to inheritance.

First, you need to find out something about her second hu*****and
(1) Is there any pre-marital agreement between the second hu*****and and A?
(2) How long does the marriage last?
(3) Who dies first, the woman A and the second hu*****and?

Based on these, we can further divided A's asset.
