Input: Article: Hellenistic art saw a turn from the idealistic, perfected, calm and composed figures of classical Greek art to a style dominated by realism and the depiction of emotion (pathos) and character (ethos). The motif of deceptively realistic naturalism in art (aletheia) is reflected in stories such as that of the painter Zeuxis, who was said to have painted grapes that seemed so real that birds came and pecked at them. The female nude also became more popular as epitomized by the Aphrodite of Cnidos of Praxiteles and art in general became more erotic (e.g. Leda and the Swan and Scopa's Pothos). The dominant ideals of Hellenistic art were those of sensuality and passion.

Now answer this question: Who is the artist that drew grapes so lifelike, birds flew up and pecked at them?

Output: Zeuxis

Article: Chinese characters represent words of the language using several strategies. A few characters, including some of the most commonly used, were originally pictograms, which depicted the objects denoted, or simple ideograms, in which meaning was expressed iconically. Some other words were expressed by compound ideograms, but the vast majority were written using the rebus principle, in which a character for a similarly sounding word was either simply borrowed or (more commonly) extended with a disambiguating semantic marker to form a phono-semantic compound character.

Question: What are some words expressed in?
Ans: compound ideograms

The fauna in the state is just as diverse as the flora and varies greatly due to the large contrast in climates. In the mountain zone of the state the most observed mammals are: Mexican fox squirrel (Sciurus nayaritensis), antelope jackrabbit (Lepus alleni), raccoon (Procyon lotor), hooded skunk (Mephitis macroura), wild boar (Sus scrofa), collared peccary (Pecari tajacu), white-tailed deer (Odocoileus virginianus), mule deer Odocoileus hemionus, American bison Bison bison, cougar (Puma concolor), eastern cottontail Sylvilagus floridanus, North American porcupine Erethizon dorsatum, bobcat Lynx rufus, Mexican wolf Canis lupus baileyi, and coyote Canis latrans. American black bear Ursus americanus is also found but in very small numbers. The Mexican wolf, once abundant, has been extirpated. The main cause of degradation has been grazing. Although there are many reptilian species in the mountains the most observed species include: Northern Mexican pine snake, Pituophis deppei jani, Texas horned lizard (Phrynosoma cornutum), rock rattlesnake (Crotalus lepidus), black-tailed rattlesnake (Crotalus molossus), and plateau tiger salamander Ambystoma velasci, one of possibly many amphibians to be found in the mountains.
The main cause of degradation has been what?
****
The answer: grazing

Back in America the scene had still not progressed beyond a small number of clubs in Chicago, Detroit, Newark and New York City. However, many independent Chicago-based record labels were making appearances on the Dance Chart with their releases. In the UK, any house song released by a Chicago-based label was routinely considered a must play at many clubs playing house music. Paradise Garage in New York City was still a top club. The emergence of Todd Terry, a pioneer of the genre, was important in America. His cover of Class Action's Larry Levan mixed "Weekend" demonstrated the continuum from the underground disco to a new house sound with hip-hop influences evident in the quicker sampling and the more rugged bass-line.
what was a top club for house music in new york city?
****
The answer:
Paradise Garage
