Please answer this: Extract the answer to the question from the following context. Question: What conflict did Britain encounter in Africa? 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.

Please answer this: Extract the answer to the question from the following context. Question: What sort of missiles are used by the defense system manufactured by Russia? Context: If current trends continue, missiles will replace gun systems completely in "first line" service.[citation needed] Guns are being increasingly pushed into specialist roles, such as the Dutch Goalkeeper CIWS, which uses the GAU-8 Avenger 30 mm seven-barrel Gatling gun for last ditch anti-missile and anti-aircraft defence. Even this formerly front-line weapon is currently being replaced by new missile systems, such as the RIM-116 Rolling Airframe Missile, which is smaller, faster, and allows for mid-flight course correction (guidance) to ensure a hit. To bridge the gap between guns and missiles, Russia in particular produces the Kashtan CIWS, which uses both guns and missiles for final defence. Two six-barrelled 30 mm Gsh-6-30 Gatling guns and 9M311 surface-to-air missiles provide for its defensive capabilities.

Answer: 9M311 surface-to-air missiles


Please answer this: Extract the answer to the question from the following context. Question: Who does Sowell consider to be the main losers in affirmative action? Context: Terry Eastland, the author who wrote From Ending Affirmative Action: The Case for Colorblind Justice states, "Most arguments for affirmative action fall into two categories: remedying past discrimination and promoting diversity". Eastland believes that the founders of affirmative action did not anticipate how the benefits of affirmative action would go to those who did not need it, mostly middle class minorities. Additionally, she argues that affirmative action carries with it a stigma that can create feelings of self-doubt and entitlement in minorities. Eastland believes that affirmative action is a great risk that only sometimes pays off, and that without it we would be able to compete more freely with one another. Libertarian economist Thomas Sowell identified what he says are negative results of affirmative action in his book, Affirmative Action Around the World: An Empirical Study. Sowell writes that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies; that they tend to benefit primarily the most fortunate among the preferred group (e.g., upper and middle class blacks), often to the detriment of the least fortunate among the non-preferred groups (e.g., poor white or Asian); that they reduce the incentives of both the preferred and non-preferred to perform at their best – the former because doing so is unnecessary and the latter because it can prove futile – thereby resulting in net losses for society as a whole; and that they engender animosity toward preferred groups as well.:115–147
