Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.

[Q]: original question: which wine's country is [Canada]?

answer type: Wine.
auxiliary information: Canada is a country, consisting of ten provinces and three territories, in the northern part of the continent of North America. It extends from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres in total, making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's common border with the United States forms the world's longest land border. The land now called Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the late 15th century, British and French colonies were established on the region's Atlantic coast. As a consequence of various conflicts, the United Kingdom gained and lost North American territories until left, in the late 18th century, with what mostly comprises Canada today. Pursuant to the British North America Act, on July 1, 1867, three colonies joined to form the autonomous federal Dominion of Canada. This began an accretion of provinces and territories to the new self-governing Dominion.

[Q]: original question: What class of drugs is [Vitamin D]?
answer: bisphosphonate, nicotinic acids, copper absorption inhibitor...
answer type: Drug class.
auxiliary information: Vitamin D refers to a group of fat-soluble secosteroids responsible for enhancing intestinal absorption of calcium, iron, magnesium, phosphate and zinc. In humans, the most important compounds in this group are vitamin D'CE and vitamin D'CC. Cholecalciferol and ergocalciferol can be ingested from the diet and from supplements. Very few foods contain vitamin D; synthesis of vitamin D in the skin is the major natural source of the vitamin. Dermal synthesis of vitamin D from cholesterol is dependent on sun exposure. Vitamin D from the diet or dermal synthesis from sunlight is biologically inactive; activation requires enzymatic conversion in the liver and kidney. Evidence indicates the synthesis of vitamin D from sun exposure is regulated by a negative feedback loop that prevents toxicity, but because of uncertainty about the cancer risk from sunlight, no recommendations are issued by the Institute of Medicine, for the amount of sun exposure required to meet vitamin D requirements. Accordingly, the Dietary Reference Intake for vitamin D assumes no synthesis occurs and all of a person's vitamin D is from food intake, although that will rarely occur in practice.
