Problem: Infrared:

Earth's surface and the clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to atmosphere. Certain substances in the atmosphere, chiefly cloud droplets and water vapor, but also carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, and chlorofluorocarbons, absorb this infrared, and re-radiate it in all directions including back to Earth. Thus, the greenhouse effect keeps the atmosphere and surface much warmer than if the infrared absorbers were absent from the atmosphere.

What substances absorb the sulfur hexafluoride emitted by the Earth?

A: unanswerable

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
For centuries, Paris has attracted artists from around the world, who arrive in the city to educate themselves and to seek inspiration from its vast pool of artistic resources and galleries. As a result, Paris has acquired a reputation as the "City of Art". Italian artists were a profound influence on the development of art in Paris in the 16th and 17th centuries, particularly in sculpture and reliefs. Painting and sculpture became the pride of the French monarchy and the French royals commissioned many Parisian artists to adorn their palaces during the French Baroque and Classicism era. Sculptors such as Girardon, Coysevox and Coustou acquired reputations as the finest artists in the royal court in 17th-century France. Pierre Mignard became the first painter to King Louis XIV during this period. In 1648, the Académie royale de peinture et de sculpture (Royal Academy of Painting and Sculpture) was established to accommodate for the dramatic interest in art in the capital. This served as France's top art school until 1793.
Who was the first painter to King Louis XIV?
A: Pierre Mignard

Question: Starting in 1236, the Mongol prince Kublai, who later ruled as Khagan from 1260–1294, was granted a large appanage in North China by his superior, Ögedei Khan. Karma Pakshi, 2nd Karmapa Lama (1203–1283)—the head lama of the Karma Kagyu lineage of Tibetan Buddhism—rejected Kublai's invitation, so instead Kublai invited Drogön Chögyal Phagpa (1235–1280), successor and nephew of Sakya Pandita, who came to his court in 1253. Kublai instituted a unique relationship with the Phagpa lama, which recognized Kublai as a superior sovereign in political affairs and the Phagpa lama as the senior instructor to Kublai in religious affairs. Kublai also made Drogön Chögyal Phagpa the director of the government agency known as the Bureau of Buddhist and Tibetan Affairs and the ruling priest-king of Tibet, which comprised thirteen different states ruled by myriarchies.
Is there an answer to this question: How many states were ruled by myriarchies?
