Answer: 4
Explanation: I would say 4 because divorce does not always indicate argumentativeness it could be the other person's fault just as much (1) and second marriages in fact do not usually fail. (2) Actually, I would say they succeed more because the first marriage or the first person might have just not been the right fit for them. And 3, people sometimes think they have matured and ready for a new marriage when they truly aren't. So I would say 4, but it could also be 3 :/
