[Q]: Extract the answer to the question from the following context. Question: What era did Britain have the most power? Context: In Britain's "imperial century", victory over Napoleon left Britain without any serious international rival, other than Russia in central Asia. Unchallenged at sea, Britain adopted the role of global policeman, a state of affairs later known as the Pax Britannica, and a foreign policy of "splendid isolation". Alongside the formal control it exerted over its own colonies, Britain's dominant position in world trade meant that it effectively controlled the economies of many nominally independent countries, such as China, Argentina and Siam, which has been generally characterized as "informal empire". Of note during this time was the Anglo-Zulu War, which was fought in 1879 between the British Empire and the Zulu Empire.

[Q]: Extract the answer to the question from the following context. Question: Where is Guam found? Context: The island of Guam is 30 miles (50 km) long and 4 to 12 miles (6 to 19 km) wide, 3⁄4 the size of Singapore. The island experiences occasional earthquakes due to its location on the western edge of the Pacific Plate and near the Philippine Sea Plate. In recent years, earthquakes with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike the Anatahan volcano in the Northern Mariana Islands, Guam is not volcanically active. However, due to its proximity to Anatahan, vog (i.e. volcanic smog) does occasionally affect Guam.

[Q]: Extract the answer to the question from the following context. Question: What is an advantage of the changes? Context: Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature. Cooling is the primary technology used to maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation, autoclavation, drying, salting, and separation of various components, all of which appearing to alter the original nutritional contents of food. Pasteurisation and autoclavation (heating techniques) have no doubt improved the safety of many common foods, preventing epidemics of bacterial infection. But some of the (new) food processing technologies have downfalls as well.

[A]: foods to last longer without becoming spoiled


[Q]: Extract the answer to the question from the following context. Question: Whose opinion is it that the burden of keeping society from being led astray is on the shoulders of men such as Atticus? Context: Absent mothers and abusive fathers are another theme in the novel. Scout and Jem's mother died before Scout could remember her, Mayella's mother is dead, and Mrs. Radley is silent about Boo's confinement to the house. Apart from Atticus, the fathers described are abusers. Bob Ewell, it is hinted, molested his daughter, and Mr. Radley imprisons his son in his house until Boo is remembered only as a phantom. Bob Ewell and Mr. Radley represent a form of masculinity that Atticus does not, and the novel suggests that such men as well as the traditionally feminine hypocrites at the Missionary Society can lead society astray. Atticus stands apart as a unique model of masculinity; as one scholar explains: "It is the job of real men who embody the traditional masculine qualities of heroic individualism, bravery, and an unshrinking knowledge of and dedication to social justice and morality, to set the society straight."
