Q: Extract the answer to the question from the following context. Question: Which country participated at the Geneva summit together with the three western democracies? Context: In 1955 American nuclear arms policy became one aimed primarily at arms control as opposed to disarmament. The failure of negotiations over arms until 1955 was due mainly to the refusal of the Russians to permit any sort of inspections. In talks located in London that year, they expressed a willingness to discuss inspections; the tables were then turned on Eisenhower, when he responded with an unwillingness on the part of the U.S. to permit inspections. In May of that year the Russians agreed to sign a treaty giving independence to Austria, and paved the way for a Geneva summit with the U.S., U.K. and France. At the Geneva Conference Eisenhower presented a proposal called "Open Skies" to facilitate disarmament, which included plans for Russia and the U.S. to provide mutual access to each other's skies for open surveillance of military infrastructure. Russian leader Nikita Khrushchev dismissed the proposal out of hand.
A: Russia

Q: Extract the answer to the question from the following context. Question: what is the article about Context: Zinc deficiency is crop plants' most common micronutrient deficiency; it is particularly common in high-pH soils. Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia, and substantial responses to zinc fertilization have been reported in these areas. Plants that grow in soils that are zinc-deficient are more susceptible to disease. Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread.
A:
Zinc deficiency
