Answer: Fathers have nearly tripled their time with their children (from 2.5 hours in 1965 to 7.3 hours per week in 2011). Therefore, the correct answer is D. "Increased threefold."
Explanation: After a decline in the 1970s and ’80s, mothers’ time with their children has also increased, and today’s mothers spend more time with their children than mothers did in the 1960s.
There are several reasons why fathers spend more time with their children now than they did in the past. One reason is that fathers have become more involved in child-rearing as gender roles have changed1. Another reason is that fathers have become more aware of the importance of spending time with their children2. Additionally, fathers have become more involved in child-rearing because it has become more economically necessary than in the past1.
Hope this helps, and have a great day!
