The initial assault by North Korean KPA forces were aided by the use of Soviet T-34-85 tanks. A North Korean tank corps equipped with about 120 T-34s spearheaded the invasion. These drove against a ROK Army with few anti-tank weapons adequate to deal with the Soviet T-34s. Additional Soviet armor was added as the offensive progressed. The North Korean tanks had a good deal of early successes against South Korean infantry, elements of the 24th Infantry Division, and those United States built M24 Chaffee light tanks that they encountered. Interdiction by ground attack aircraft was the only means of slowing the advancing Korean armor. The tide turned in favour of the United Nations forces in August 1950 when the North Koreans suffered major tank losses during a series of battles in which the UN forces brought heavier equipment to bear, including M4A3 Sherman medium tanks backed by U.S. M26 heavy tanks, along with the British Centurion, Churchill, and Cromwell tanks.
What helped the UN forces and shifted the war in their favor?
the North Koreans suffered major tank losses

Input: Copper
The metal's distinctive natural green patina has long been coveted by architects and designers. The final patina is a particularly durable layer that is highly resistant to atmospheric corrosion, thereby protecting the underlying metal against further weathering. It can be a mixture of carbonate and sulfate compounds in various amounts, depending upon environmental conditions such as sulfur-containing acid rain. Architectural copper and its alloys can also be 'finished' to embark a particular look, feel, and/or color. Finishes include mechanical surface treatments, chemical coloring, and coatings.

What conditions effect the mixture of carbonate and sulfate in copper?
Output: environmental

Here is a question about this article: Cheesemaking is an ancient tradition in most Alpine countries. A wheel of cheese from the Emmental in Switzerland can weigh up to 45 kg (100 lb), and the Beaufort in Savoy can weight up to 70 kilograms (150 lb). Owners of the cows traditionally receive from the cheesemakers a portion in relation to the proportion of the cows' milk from the summer months in the high alps. Haymaking is an important farming activity in mountain villages which has become somewhat mechanized in recent years, although the slopes are so steep that usually scythes are necessary to cut the grass. Hay is normally brought in twice a year, often also on festival days. Alpine festivals vary from country to country and often include the display of local costumes such as dirndl and trachten, the playing of Alpenhorns, wrestling matches, some pagan traditions such as Walpurgis Night and, in many areas, Carnival is celebrated before Lent.
