In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

Input: Consider Input: The enzyme LCAT catalyzes the formation of an ester from this compound. Intermediates in the synthesis of this compound include squalene [SKWAY-leen] and mevalonate [muh-VAL-uh-nate], the latter of which is produced by HMG-CoA reductase. Vitamin D is formed from the 7-dehydro form of this compound, which reduces membrane fluidity. This compound, which is transported to the liver by high-density lipoprotein, is linked to heart disease. For 10 points, name this compound whose amount in the blood is lowered by statins such as Crestor and Lipitor.

Output: Science

Input: Consider Input: A version of spectroscopy that is free of one form of this effect uses a standing wave to give radiation to a moving atom and is named for its two-photon transition. Due to this effect, atoms observe laser resonance leading to the phenomenon of optical molasses at its namesake cooling limit. Mossbauer spectroscopy uses this effect to modulate the energy of the incident gamma rays. An experiment that used a canal ray tube and a mirror to view light emissions was used to detect the transverse form of this effect, while its relativistic form involves changes equal to the square root of one plus beta over one minus beta. For 10 points, name this shift in the wavelength from a moving source that can be heard by an observer.

Output: Science

Input: Consider Input: One leader of this town wrote a letter that became known as his "Rude Answer," leading to the sending and eventual wreck of the Sea Venture. A violent protest against Governor William Berkeley caused this town to be burned to the ground during Bacon's Rebellion. While it was directed by George Percy, many inhabitants of this town died during its "Starving Time," due to their dependence upon trade with the Powhatan. For 10 points, John Rolfe and John Smith led what Virginia town, the first permanent English settlement in the United States
