Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Glacial abrasion is commonly characterized by glacial striations. Glaciers produce these when they contain large boulders that carve long scratches in the bedrock. By mapping the direction of the striations, researchers can determine the direction of the glacier's movement. Similar to striations are chatter marks, lines of crescent-shape depressions in the rock underlying a glacier. They are formed by abrasion when boulders in the glacier are repeatedly caught and released as they are dragged along the bedrock.
What cause glacial stiations?
A: large boulders that carve long scratches in the bedrock

Context and question: Madonna entered mainstream films in February 1985, beginning with a brief appearance as a club singer in Vision Quest, a romantic drama film. Its soundtrack contained two new singles, her U.S. number-one single, "Crazy for You" and "Gambler". She also appeared in the comedy Desperately Seeking Susan in March 1985, a film which introduced the song "Into the Groove", her first number one single in the United Kingdom. Although Madonna was not the lead actress for the film, her profile was such that the movie widely became considered (and marketed) as a Madonna vehicle. The New York Times film critic Vincent Canby named it one of the ten best films of 1985.
What song did the comedy Desperately Seeking Susan promote?
Answer: "Into the Groove"

Question: Predators may increase the biodiversity of communities by preventing a single species from becoming dominant. Such predators are known as keystone species and may have a profound influence on the balance of organisms in a particular ecosystem. Introduction or removal of this predator, or changes in its population density, can have drastic cascading effects on the equilibrium of many other populations in the ecosystem. For example, grazers of a grassland may prevent a single dominant species from taking over.
