I didnt like any of the answer choices and this CR seem to be purposefully convuluted.
Only B has some reference at all.
Here are the facts
Women with preschool age children = 7.6 mill
Women who are Sole bringers of money = 6.4 mill
We do not know the proportion of sole bringers vs ones where the men also bring in money.
The probable results therefore are these.
1. 6.4 million of the sole bringers of money COULD be in fact a part of the 7.6 million women with preschool age children; i.e. MOST of the 7.6 women with children are sole bringers of money.
2. A portion of the 6.4 million of the sole bringers of money could constitute a small to substantial part of the 7.6 million
3. the 6.4 million women who are sole bringers of money may be exclusive of this set -> ie. ALL the 7.6 million women with children are with men who bring money as well.
Therefore the conclusion that "relatively few women are in families where the man brings in money too" may not necessarily be true.
Option B does exactly this.
Hope that helps.
