1. On Sunday they each did their homework for only 30 minutes.
2. On Saturday Jessie watched 3 hours TV, Nina watched 2 hours and 30 minutes of TV, and Ruka watched 4 hours on TV instead of using his time wisely and doing his home work.
3. Yes it is true because Jessie watches more TV then doing her homework / She did her homework for 2 hour the whole week.
