Problem: Extract the answer to the question from the following context. Question: What is a helpful driver of evolution? Context: Chapter I covers animal husbandry and plant breeding, going back to ancient Egypt. Darwin discusses contemporary opinions on the origins of different breeds under cultivation to argue that many have been produced from common ancestors by selective breeding. As an illustration of artificial selection, he describes fancy pigeon breeding, noting that "[t]he diversity of the breeds is something astonishing", yet all were descended from one species of rock pigeon. Darwin saw two distinct kinds of variation: (1) rare abrupt changes he called "sports" or "monstrosities" (example: ancon sheep with short legs), and (2) ubiquitous small differences (example: slightly shorter or longer bill of pigeons). Both types of hereditary changes can be used by breeders. However, for Darwin the small changes were most important in evolution.

A: ubiquitous small differences

Problem: Given the question: Extract the answer to the question from the following context. Question: when did rick monday say, "if you're going to burn the flag, don't do it around me? Context: On April 25, 1976, at Dodger Stadium, father-and-son protestors ran into the outfield and tried to set fire to a U.S. flag. When Cubs outfielder Rick Monday noticed the flag on the ground and the man and boy fumbling with matches and lighter fluid, he dashed over and snatched the flag to thunderous applause. When he came up to bat in the next half-inning, he got a standing ovation from the crowd and the stadium titantron flashed the message, "RICK MONDAY... YOU MADE A GREAT PLAY..." Monday later said, "If you're going to burn the flag, don't do it around me. I've been to too many veterans' hospitals and seen too many broken bodies of guys who tried to protect it."

Extract the answer to the question from the following context. Question: Who is an example of this consternation? Context: There were serious scientific objections to the process of natural selection as the key mechanism of evolution, including Karl von Nägeli'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: Which british ships fought with North Korea on 2 July 1950? Context: Because neither Korea had a significant navy, the Korean War featured few naval battles. A skirmish between North Korea and the UN Command occurred on 2 July 1950; the U.S. Navy cruiser USS Juneau, the Royal Navy cruiser HMS Jamaica, and the frigate HMS Black Swan fought four North Korean torpedo boats and two mortar gunboats, and sank them. USS Juneau later sank several ammunition ships that had been present. The last sea battle of the Korean War occurred at Inchon, days before the Battle of Incheon; the ROK ship PC-703 sank a North Korean mine layer in the Battle of Haeju Island, near Inchon. Three other supply ships were sunk by PC-703 two days later in the Yellow Sea. Thereafter, vessels from the UN nations held undisputed control of the sea about Korea. The gun ships were used in shore bombardment, while the aircraft carriers provided air support to the ground forces.
