Answer each of questions below and each question should be at least 250 words.
Question1：
Personality changes vary from individual to individual, but some general trends are also observed. For instance, while openness and extraversion decline, conscientiousness increases across early adulthood. Agreeableness is generally flat until mid-adulthood, where it then increases. What factors do you think account for these changes, and how would they account for the “individual differences” we observe over the course of adulthood?
Question2：
Many studies have shown a U-shaped curve of marital happiness, with declines in satisfaction over the course of one’s marital life and then, about 20-25 years later, an increase back to pre/early-marriage levels. Of course, not all individual will show this trend. What factors do you think help to offset, or attenuate, this decline in marital satisfaction over time?
Question 3：
Divorce is a common outcome of unhappy marriages, with the divorce rate hovering around 50% in Canada. The implications of divorce for parents and children are highly consequential. Based on your reading and other literature, under what conditions do you think divorce is a more desirable outcome than staying together in an unhappy marriage? Are there such circumstances? What are the ramifications of divorce on children and parents should parents opt to separate?
