[Q]: Extract the answer to the question from the following context. Question: When were William Thomson and Fleeming Jenkin's opposing views successfully addressed? Context: There were serious scientific objections to the process of natural selection as the key mechanism of evolution, including Karl von Nageli's insistence that a trivial characteristic with no adaptive advantage could not be developed by selection. Darwin conceded that these could be linked to adaptive characteristics. His estimate that the age of the Earth allowed gradual evolution was disputed by William Thomson (later awarded the title Lord Kelvin), who calculated that it had cooled in less than 100 million years. Darwin accepted blending inheritance, but Fleeming Jenkin calculated that as it mixed traits, natural selection could not accumulate useful traits. Darwin tried to meet these objections in the 5th edition. Mivart supported directed evolution, and compiled scientific and religious objections to natural selection. In response, Darwin made considerable changes to the sixth edition. The problems of the age of the Earth and heredity were only resolved in the 20th century.

[Q]: Extract the answer to the question from the following context. Question: Who were the French helping? Context: Two days after the marriage, Bonaparte left Paris to take command of the Army of Italy. He immediately went on the offensive, hoping to defeat the forces of Piedmont before their Austrian allies could intervene. In a series of rapid victories during the Montenotte Campaign, he knocked Piedmont out of the war in two weeks. The French then focused on the Austrians for the remainder of the war, the highlight of which became the protracted struggle for Mantua. The Austrians launched a series of offensives against the French to break the siege, but Napoleon defeated every relief effort, scoring notable victories at the battles of Castiglione, Bassano, Arcole, and Rivoli. The decisive French triumph at Rivoli in January 1797 led to the collapse of the Austrian position in Italy. At Rivoli, the Austrians lost up to 14,000 men while the French lost about 5,000.

[Q]: Extract the answer to the question from the following context. Question: This thing, mostly used as a pure metal, is also used in the production of compounds for what plant-related industry? Context: The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a pure metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics.
