However, certain higher ranks have additional powers to authorize certain aspects of police operations, such as a power to authorize a search of a suspect's house (section 18 PACE in England and Wales) by an officer of the rank of Inspector, or the power to authorize a suspect's detention beyond 24 hours by a Superintendent.

The first issue was ammunition. Before the war it was recognised that ammunition needed to explode in the air. Both high explosive (HE) and shrapnel were used, mostly the former. Airburst fuses were either igniferious (based on a burning fuse) or mechanical (clockwork). Igniferious fuses were not well suited for anti-aircraft use. The fuse length was determined by time of flight, but the burning rate of the gunpowder was affected by altitude. The British pom-poms had only contact-fused ammunition. Zeppelins, being hydrogen filled balloons, were targets for incendiary shells and the British introduced these with airburst fuses, both shrapnel type-forward projection of incendiary 'pot' and base ejection of an incendiary stream. The British also fitted tracers to their shells for use at night. Smoke shells were also available for some AA guns, these bursts were used as targets during training.

What were hydrogen filled balloons called?
Answer: Zeppelins

Problem: In 1948, Eisenhower became President of Columbia University, an Ivy League university in New York City. The assignment was described as not being a good fit in either direction. During that year Eisenhower's memoir, Crusade in Europe, was published. Critics regarded it as one of the finest U.S. military memoirs, and it was a major financial success as well. Eisenhower's profit on the book was substantially aided by an unprecedented ruling by the U.S. Department of the Treasury that Eisenhower was not a professional writer, but rather, marketing the lifetime asset of his experiences, and thus he only had to pay capital gains tax on his $635,000 advance instead of the much higher personal tax rate. This ruling saved Eisenhower about $400,000.
What was the title of Eisenhower's memoir?
The answer is the following: Crusade in Europe

Intercommunal violence erupted on December 21, 1963, when two Turkish Cypriots were killed at an incident involving the Greek Cypriot police. The violence resulted in the death of 364 Turkish and 174 Greek Cypriots, destruction of 109 Turkish Cypriot or mixed villages and displacement of 25,000-30,000 Turkish Cypriots. The crisis resulted in the end of the Turkish Cypriot involvement in the administration and their claiming that it had lost its legitimacy; the nature of this event is still controversial. In some areas, Greek Cypriots prevented Turkish Cypriots from travelling and entering government buildings, while some Turkish Cypriots willingly withdrew due to the calls of the Turkish Cypriot administration. Turkish Cypriots started living in enclaves; the republic's structure was changed unilaterally by Makarios and Nicosia was divided by the Green Line, with the deployment of UNFICYP troops.
How many Turkish Cypriots were displaced due to the violence?
25,000-30,

By the 1860s the Kingdom of Prussia and the Austrian Empire were the two most powerful nations dominated by German-speaking elites. Both sought to expand their influence and territory. The Austrian Empire like the Holy Roman Empire was a multi-ethnic state, but German-speaking people there did not have an absolute numerical majority; the creation of the Austro-Hungarian Empire was one result of the growing nationalism of other ethnicities especially the Hungarians. Prussia under Otto von Bismarck would ride on the coat-tails of nationalism to unite all of modern-day Germany. The German Empire ("Second Reich") was created in 1871 following the proclamation of Wilhelm I as head of a union of German-speaking states, while disregarding millions of its non-German subjects who desired self-determination from German rule.

Which empire was a multi ethnic state?
Output: The Austrian Empire

Problem: Please answer a question about the following article about Houston:
When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of non-discrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years.
What world event caused this increased need for petrochemicals?
A:
World War II
