Which best defines a topic and position in an argumentative essay about household chores? I don’t like doing chores, but my parents insist that I clean my room, pick up the trash, and feed our cats. They say it is good for me.

Some chores are boring, like sweeping the floor and cleaning bathrooms. Some chores are more exciting, like washing the car and digging in the garden. Some people think making dessert is a fun chore.

Listening to music and sharing a job with a friend are both ways to complete work faster. Time flies when you’re having fun.

I think children should be expected to help more at home. Doctors and teachers agree that children who learn to complete chores are healthier and better students than children who do not.
