Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It was also the exclusive carrier of Canadian Curling Association events during the 2004–2005 season. Due to disappointing results and fan outrage over many draws being carried on CBC Country Canada (now called Cottage Life Television, the association tried to cancel its multiyear deal with the CBC signed in 2004.

Context and question: The macronutrients are carbohydrates, fats, protein, and water. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in Joules or kilocalories (often called "Calories" and written with a capital C to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram, though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons.
Which category is represented by carbohydrates and fats among other nutrients?
Answer: macronutrients

Question: At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.
Is there an answer to this question: What sytle did the new style of mandolins supplant?

Answer:
European-style bowl-back
