According to the study cited by the u.s. census bureau, children who live with married parents grow up with more advantages than children who live with: a divorced parent
a single parent
a grandparent
all of the above

the correct answer is all of the above.

Explanation: A child development is influenced in many ways such as their background, health and environment.. Children go through significant family changes such as a family break-up or a new step-family. These can affect a child's emotional and intellectual development.

I believe that the question is false; there isn't one province in Canada that has more than half of the country's population.

You could answer it it two ways:

Half of the country's population lives in two provinces: Ontario and Quebec.

The smallest Province is Prince Edward's Land, which has a high population for its size-  140 000, which is bigger than two other provinces, but far from being half the population of Canada.
