Input: Read this: The simplest model capacitor consists of two thin parallel conductive plates separated by a dielectric with permittivity ε . This model may also be used to make qualitative predictions for other device geometries. The plates are considered to extend uniformly over an area A and a charge density ±ρ = ±Q/A exists on their surface. Assuming that the length and width of the plates are much greater than their separation d, the electric field near the centre of the device will be uniform with the magnitude E = ρ/ε. The voltage is defined as the line integral of the electric field between the plates
Question: What equation describes the charge density for an ideal model of a capacitor?

Output: ±ρ = ±Q/A


Input: Read this: In 1968, while selling 50 million comic books a year, company founder Goodman revised the constraining distribution arrangement with Independent News he had reached under duress during the Atlas years, allowing him now to release as many titles as demand warranted. Late that year he sold Marvel Comics and his other publishing businesses to the Perfect Film and Chemical Corporation, which continued to group them as the subsidiary Magazine Management Company, with Goodman remaining as publisher. In 1969, Goodman finally ended his distribution deal with Independent by signing with Curtis Circulation Company.
Question: To whom was Marvel sold in 1968?

Output: the Perfect Film and Chemical Corporation


Input: Read this: Mali lies in the torrid zone and is among the hottest countries in the world. The thermal equator, which matches the hottest spots year-round on the planet based on the mean daily annual temperature, crosses the country. Most of Mali receives negligible rainfall and droughts are very frequent. Late June to early December is the rainy season in the southernmost area. During this time, flooding of the Niger River is common, creating the Inner Niger Delta. The vast northern desert part of Mali has a hot desert climate (Köppen climate classification (BWh) with long, extremely hot summers and scarce rainfall which decreases northwards. The central area has a hot semi-arid climate (Köppen climate classification (BSh) with very high temperatures year-round, a long, intense dry season and a brief, irregular rainy season. The little southern band possesses a tropical wet and dry climate (Köppen climate classification (Aw) very high temperatures year-round with a dry season and a rainy season.
Question: Where is there a brief intense dry season?

Output: unanswerable


Input: Read this: DDT, sprayed on the walls of houses, is an organochlorine that has been used to fight malaria since the 1950s. Recent policy statements by the World Health Organization have given stronger support to this approach. However, DDT and other organochlorine pesticides have been banned in most countries worldwide because of their persistence in the environment and human toxicity. DDT use is not always effective, as resistance to DDT was identified in Africa as early as 1955, and by 1972 nineteen species of mosquito worldwide were resistant to DDT.
Question: How supportive is Africa about DDT being banned?

Output:
unanswerable
