[填空题]Questions 47 to 51 are based on the following passage.
America is a country that now sits atop the cherished myth that work provides rewards, that working people can support their families. It’s a myth that has become so divorced from reality that it might as well begin with the words "once upon a time". Today 1.6 million New Yorkers suffer from "food insecurity", which is a fancy way of saying they don’t have enough to eat.

In September 1966, Canada’s population passed the 20 million mark. Most of this surging growth came from natural increase.

This rate of increase had been exceeded only once before in Canada’s history, in the decade before 1911 when the prairies were being settled.
Undoubtedly, the good economic conditions of the 1950s supported a growth in the population, but the expansion also derived from a trend toward earlier marriages and an increase in the average size of
A. Educational changes in Canadian society.
B. Canada during the Second World War.
