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.

Ex Input:
Founder-flush models of this phenomenon propose that it may result from repeated bottlenecks. Changes of ploidy in plants can cause this process due to the frequent sterility of the resulting offspring. The(*) sympatric version of this phenomena occurs between populations in the same region, and punctuated equilibria are a sign of the allopatric variety of this process in the fossil record. For 10 points, name this biological process, in which populations become reproductively isolated and diverge, leading to the formation of new species.

Ex Output:
Social Science


Ex 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.

Ex Output:
Science


Ex Input:
The strength of this phenomenon can be measured using the Wilhelmy plate method. The dispersion relation for water waves has two terms, one governed by gravity and one governed by this phenomenon. The strength of this phenomenon is usually measured in dynes per centimeter, as it has dimensions of energy over area. The strength of this phenomenon is lowered by surfactants, and it arises because liquid molecules at an interface experience attractive hydrogen bonds only from one side. For 10 points, name this phenomenon which allows water striders to walk on water, a cohesion observed in liquids on their interface with air.

Ex Output:

Science
