Answer:

option C
Explanation:
we know that gravity is strongest when two large objects are near each other--so, when the asteroid reaches point C (which is shown to be closest to the sun), the pull of gravity will be greatest. 
We also know that the attraction/pull of gravity slows down objects, so, the asteroid will be going slowest at its point of strongest gravity--which we have determined to be point C
hope this helps! let me know if you need more explanation, have a lovely day :)

Answer:
With the findings of the 2016 Census count on population and dwellings, Statistics Canada gives Canadians a first look at the most recent national statistical snapshot.
The census counts 35,151,728 persons who said they lived in Canada on May 10, 2016, and displays population growth patterns across the country.
The organization will provide the complete spectrum of census data during the following year, as Canadians commemorate 150 years since Confederation, in order to portray a truthful picture of Canadians' lives and communities.
In 1871, the first census following Confederation recorded 3.5 million people in Canada, while the population figure in 2016 was ten times higher. When Canadians celebrated the 100th anniversary of Confederation in 1967, that number had risen to 20.0 million people (1966 Census).
Canadians have been making their way west for many years. The four founding provinces of Ontario, Quebec, New Brunswick, and Nova Scotia housed the majority of Canadians in 1871, whereas Western Canada was lightly populated. Manitoba, Saskatchewan, Alberta, and British Columbia accounted for over a third of the population in 2016.:
