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: 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‚ÇÉ and vitamin D‚ÇÇ. 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.

Q: original question: Which ship builder built [USS Forrestal (CV-59)]?
answer: northrop grumman shipbuilding
answer type: Ship Builder.
auxiliary information: USS Forrestal (CV-59), formerly AVT-59 and CVA-59, was a supercarrier named after the first Secretary of Defense James Forrestal. Commissioned in 1955, she was the first completed supercarrier, and was the lead ship of her class. Unlike the successor Nimitz-class, the Forrestal and her class were conventionally powered. The other carriers of her class were the USS Saratoga, USS Ranger and USS Independence. She superseded the World War II Japanese carrier Shinano as the largest aircraft carrier ever built in terms of full load displacement and was the first to specifically support jet aircraft. The ship was affectionately called "The FID", because James Forrestal was the first ever Secretary of Defense, FID standing for "First In Defense". This is also the slogan on the ship's insignia and patch. She was also informally known in the fleet as the "USS Zippo" and "Forest Fire" or "Firestal" because of a number of highly publicized fires on board, most notably a 1967 incident in which 134 sailors died and an additional 161 were injured. Forrestal served for nearly four decades in the Atlantic, Mediterranean, and Pacific. She was decommissioned in 1993, and made available as a museum.

Name the builder of the ship [USS Forrestal (CV-59)].
