Problem: United States presidential election, 2004:

To distinguish official campaigning from independent campaigning, political advertisements on television were required to include a verbal disclaimer identifying the organization responsible for the advertisement. Advertisements produced by political campaigns usually included the statement, "I'm [candidate's name], and I approve this message." Advertisements produced by independent organizations usually included the statement, "[Organization name] is responsible for the content of this advertisement", and from September 3 (60 days before the general election), such organizations' ads were prohibited from mentioning any candidate by name. Previously, television advertisements only required a written "paid for by" disclaimer on the screen.

How were viewers able to determine who endorsed political campaign ads, they saw in advertisements??

A: required to include a verbal disclaimer identifying the organization responsible for the advertisement

Problem: Emotion:

In economics, the social science that studies the production, distribution, and consumption of goods and services, emotions are analyzed in some sub-fields of microeconomics, in order to assess the role of emotions on purchase decision-making and risk perception. In criminology, a social science approach to the study of crime, scholars often draw on behavioral sciences, sociology, and psychology; emotions are examined in criminology issues such as anomie theory and studies of "toughness," aggressive behavior, and hooliganism. In law, which underpins civil obedience, politics, economics and society, evidence about people's emotions is often raised in tort law claims for compensation and in criminal law prosecutions against alleged lawbreakers (as evidence of the defendant's state of mind during trials, sentencing, and parole hearings). In political science, emotions are examined in a number of sub-fields, such as the analysis of voter decision-making.

Along with criminal law, what facet of law doesn't consider evidence related to emotion?

A: unanswerable


Problem: Near East:

Until about 1855 the words near east and far east did not refer to any particular region. The far East, a phrase containing a noun, East, qualified by an adjective, far, could be at any location in the "far east" of the speaker's home territory. The Ottoman Empire, for example, was the far East as much as the East Indies. The Crimean War brought a change in vocabulary with the introduction of terms more familiar to the late 19th century. The Russian Empire had entered a more aggressive phase, becoming militarily active against the Ottoman Empire and also against China, with territorial aggrandizement explicitly in mind. Rethinking its policy the British government decided that the two polities under attack were necessary for the balance of power. It therefore undertook to oppose the Russians in both places, one result being the Crimean War. During that war the administration of the British Empire began promulgating a new vocabulary, giving specific regional meaning to "the Near East," the Ottoman Empire, and "the Far East," the East Indies. The two terms were now compound nouns often shown hyphenated.

What brought a change in vocabulary?

A:
The Crimean War
