Many were surprised by these changes to the CBC schedule, which were apparently intended to attract a younger audience to the network; some suggested they might alienate the core CBC viewership. Another note of criticism was made when the network decided to move The National in some time zones to simulcast the American version of The One over the summer. This later became a moot point, as The One was taken off the air after two weeks after extremely low American and Canadian ratings, and the newscast resumed its regular schedule.
For what purpose did CBC make significant changes to their broadcasting?
A: to attract a younger audience to the network

Between 1948 and 1958, the Jewish population rose from 800,000 to two million. Currently, Jews account for 75.4% of the Israeli population, or 6 million people. The early years of the State of Israel were marked by the mass immigration of Holocaust survivors in the aftermath of the Holocaust and Jews fleeing Arab lands. Israel also has a large population of Ethiopian Jews, many of whom were airlifted to Israel in the late 1980s and early 1990s. Between 1974 and 1979 nearly 227,258 immigrants arrived in Israel, about half being from the Soviet Union. This period also saw an increase in immigration to Israel from Western Europe, Latin America, and North America.
Where did this period see a decrease in immigration to Israel?
A: unanswerable

Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
What is the result of using DC power on a DC motor?
A: unanswerable

Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, many animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized.
What does the ASPCA recommend for dogs who are not used for breeding purposes?
A:
neutered
