Q: Passage: The Cadet Organizations Administration and Training Service (COATS) consists of officers and non-commissioned members who conduct training, safety, supervision and administration of nearly 60,000 cadets aged 12 to 18 years in the Canadian Cadet Movement. The majority of members in COATS are officers of the Cadet Instructors Cadre (CIC) branch of the CAF. Members of the Reserve Force Sub-Component COATS who are not employed part-time (Class A) or full-time (Class B) may be held on the "Cadet Instructor Supplementary Staff List" (CISS List) in anticipation of employment in the same manner as other reservists are held as members of the Supplementary Reserve.

Q: Passage: West of the Rocky Mountains lies the Intermontane Plateaus (also known as the Intermountain West), a large, arid desert lying between the Rockies and the Cascades and Sierra Nevada ranges. The large southern portion, known as the Great Basin, consists of salt flats, drainage basins, and many small north-south mountain ranges. The Southwest is predominantly a low-lying desert region. A portion known as the Colorado Plateau, centered around the Four Corners region, is considered to have some of the most spectacular scenery in the world. It is accentuated in such national parks as Grand Canyon, Arches, Mesa Verde National Park and Bryce Canyon, among others. Other smaller Intermontane areas include the Columbia Plateau covering eastern Washington, western Idaho and northeast Oregon and the Snake River Plain in Southern Idaho.

A: What is the name of the plateau that lies east of the Rocky Mountains?

Q: Passage: The phrase is usually used in local political debates, in polemic writing or in private conversations. It is rarely used by politicians themselves in a public context, although at certain times in Canadian history political parties have used other similarly loaded imagery. In the 1988 federal election, the Liberals asserted that the proposed Free Trade Agreement amounted to an American takeover of Canada—notably, the party ran an ad in which Progressive Conservative (PC) strategists, upon the adoption of the agreement, slowly erased the Canada-U.S. border from a desktop map of North America. Within days, however, the PCs responded with an ad which featured the border being drawn back on with a permanent marker, as an announcer intoned "Here's where we draw the line."

A:
Who suggested that the Progressive Conservative amounted to an American takeover of Canada?
