This can be partially demonstrated by the fact that in 1978, 44.8% of minority working families owned their own home, while in 2003, the home ownership rate of minority working families was 44.6%.

To evaluate the argument above, it would be most useful to compare 1978 and 2003 with regard to which of the following characteristics?

A. The percentage of minority working families who did not own their own home.
B. The number of minority working families who owned homes in 1978 and still owned homes in 2003
C. The percentage of minority working families whose property values increased.
D. The percentage of non-minority working families who owned their own home.
E. The percentage of non-minority working families who live in an apartment.

I chose the right answer, but I have one more question about an extra choice. What if there's another choice, which gives us the total number of minority and non-minority families in 1978 and the total number of those in 2003, then this can be the right choice as well. Right?

Thanks.

Thanks, so when we encounter such problems, we can also treat them as math problems.
