Read the following conversation and then answer the questions
(Toti and Hamsa meet on the way to school. They are both in Grade 5.)
Toti: Hello Hamsa. How are you doing? You have really grown tall this year. Almost the height of our class teacher Mr. Tosha.
Hamsa: Haa! Toti I'm doing well. You have grown tall as well. As a matter of fact, you are already taller than Mr. Tosha!
Toti: I think this has been made possible because I have always followed the rule of three that Ms Kobole taught us.
Hamsa: The rule of three? What is that? During all of her lessons in Home Science, I have never heard of such.
Toti: Oh! Hamsa. I can remember that the day the teacher taught us, you had gone for a competition in Marema school. The rule of three simply means eating a meal with the right amounts of energy giving foods, protective foods and body building foods.
Hamsa: In other words, a balanced diet, right?
Toti: Exactly. This has really helped me maintain good health.
