Input: Article: The relatively recent increased consumption of sugar has been linked to the rise of some afflictions such as diabetes, obesity, and more recently heart disease. Increased consumption of sugar has been tied to these three, among others. Obesity levels have more than doubled in the last 30 years among adults, going from 15% to 35% in the United States. Obesity and diet also happen to be high risk factors for diabetes. In the same time span that obesity doubled, diabetes numbers quadrupled in America. Increased weight, especially in the form of belly fat, and high sugar intake are also high risk factors for heart disease. Both sugar intake and fatty tissue increase the probability of elevated LDL cholesterol in the bloodstream. Elevated amounts of Low-density lipoprotein (LDL) cholesterol, is the primary factor in heart disease. In order to avoid all the dangers of sugar, moderate consumption is paramount.

Now answer this question: What does the term LDL stand for?

Output: Low-density lipoprotein

Input: Article: Palermo is surrounded by mountains, formed of calcar, which form a cirque around the city. Some districts of the city are divided by the mountains themselves. Historically, it was relatively difficult to reach the inner part of Sicily from the city because of the mounts. The tallest peak of the range is La Pizzuta, about 1,333 m (4,373 ft.) high. However, historically, the most important mount is Monte Pellegrino, which is geographically separated from the rest of the range by a plain. The mount lies right in front of the Tyrrhenian Sea. Monte Pellegrino's cliff was described in the 19th century by Johann Wolfgang von Goethe, as "The most beautiful promontory in the world", in his essay "Italian Journey".

Now answer this question: What geographic form is Palermo surrounded by?

Output: mountains

Input: Article: Groups share a fundamental kinship with the notion of symmetry. For example, a symmetry group encodes symmetry features of a geometrical object: the group consists of the set of transformations that leave the object unchanged and the operation of combining two such transformations by performing one after the other. Lie groups are the symmetry groups used in the Standard Model of particle physics; Point groups are used to help understand symmetry phenomena in molecular chemistry; and Poincaré groups can express the physical symmetry underlying special relativity.

Now answer this question: What shares an essential relationship to groups?

Output:
symmetry
