Problem: The classification of speech varieties as dialects or languages and their relationship to other varieties of speech can be controversial and the verdicts inconsistent. English and Serbo-Croatian illustrate the point. English and Serbo-Croatian each have two major variants (British and American English, and Serbian and Croatian, respectively), along with numerous other varieties. For political reasons, analyzing these varieties as "languages" or "dialects" yields inconsistent results: British and American English, spoken by close political and military allies, are almost universally regarded as dialects of a single language, whereas the standard languages of Serbia and Croatia, which differ from each other to a similar extent as the dialects of English, are being treated by some linguists from the region as distinct languages, largely because the two countries oscillate from being brotherly to being bitter enemies. (The Serbo-Croatian language article deals with this topic much more fully.)
Why are Serbian and Croatian often treated like distinct languages?
The answer is the following: the two countries oscillate from being brotherly to being bitter enemies

Problem: In other events of the nineteenth century, The Times opposed the repeal of the Corn Laws until the number of demonstrations convinced the editorial board otherwise, and only reluctantly supported aid to victims of the Irish Potato Famine. It enthusiastically supported the Great Reform Bill of 1832, which reduced corruption and increased the electorate from 400,000 people to 800,000 people (still a small minority of the population). During the American Civil War, The Times represented the view of the wealthy classes, favouring the secessionists, but it was not a supporter of slavery.
Many demonstrations in the nineteenth century convinced The Times editorial board to finally support the repeal of what laws?
The answer is the following: Corn Laws

Problem: The Chief Deputy Whip is the primary assistant to the whip, who is the chief vote counter for his or her party. The current chief deputy majority whip is Republican Patrick McHenry. Within the House Republican Conference, the chief deputy whip is the highest appointed position and often a launching pad for future positions in the House Leadership. The House Democratic Conference has multiple chief deputy whips, led by a Senior Chief Deputy Whip, which is the highest appointed position within the House Democratic Caucus. The current senior chief deputy minority whip, John Lewis, has held his post since 1991.
Who holds the highest appointed Republican position in House?
The answer is the following: Patrick McHenry.

Problem: The emperor Julian made a short-lived attempt to revive traditional and Hellenistic religion and to affirm the special status of Judaism, but in 380 under Theodosius I, Nicene Christianity became the official state religion of the Roman Empire. Pleas for religious tolerance from traditionalists such as the senator Symmachus (d. 402) were rejected. Christianity became increasingly popular. Heretics as well as non-Christians were subject to exclusion from public life or persecution, but Rome's original religious hierarchy and many aspects of its ritual influenced Christian forms, and many pre-Christian beliefs and practices survived in Christian festivals and local traditions.
What group was excluded or persecuted by the empire?
The answer is the following:
Heretics
