On average, european women are 10 years older than women in sub-saharan africa when they have their first baby. which of the following is not a contributing factor to this?

I don't know what options there were, but i can tell you some contributing factors; maybe this helps:
-higher education of women
-higher cost of raising babies in Europe
-smaller mortality of children in Europe
-higher age of marriage in Europe
-More personal independence in Europe.

did i get any of the options right?

During the Revolution, men were off fighting for the new nation. Many of them had to take out loans to keep their farms going in their absence. After the war, the creditors wanted their money. Sometimes the states backed the debtors and ordered the creditors to forgive the debts. But, sometimes they backed the creditors and the peoples' farms - their homes - were foreclosed. Many men were put in debtor prison until family members could come up with the money to get them out.

The new nation was in a horrible crisis with inflation. The war had been financed by loans from Spain and France. The money had to be repaid, but because of the Revolution, a lot of business was lost from the former colonies. Trade with the British West Indies was gone. The new government asked the states for more money, but they said no.

The answer was to print more money, but of course, that never works. It made the money less and less valuable. So now the people had fistfuls of worthless money. So now you have all of these farmers, who had fought in the Revolution, unable to keep their farms. Now they cannot feed their family and they have no property, which at that time meant in most states they could not vote.
