Q: proper question: The Presiding Officer tries the achieve a balance between similar viewpoints and whom? 
 disfluent question: Who decides, or better yet, the Presiding Officer tries the achieve a balance between similar viewpoints and whom? 
 context: The Presiding Officer (or Deputy Presiding Officer) decides who speaks in chamber debates and the amount of time for which they are allowed to speak. Normally, the Presiding Officer tries to achieve a balance between different viewpoints and political parties when selecting members to speak. Typically, ministers or party leaders open debates, with opening speakers given between 5 and 20 minutes, and succeeding speakers allocated less time. The Presiding Officer can reduce speaking time if a large number of members wish to participate in the debate. Debate is more informal than in some parliamentary systems. Members may call each other directly by name, rather than by constituency or cabinet position, and hand clapping is allowed. Speeches to the chamber are normally delivered in English, but members may use Scots, Gaelic, or any other language with the agreement of the Presiding Officer. The Scottish Parliament has conducted debates in the Gaelic language.

Q: proper question: What weapons were the Zulus using during the Anglo-Zulu War of 1880? 
 disfluent question: What weapons were the Zulus using during the Anglo-Zulu War of 1879 rather 1880? 
 context: Along with advancements in communication, Europe also continued to advance in military technology. European chemists made deadly explosives that could be used in combat, and with innovations in machinery they were able to manufacture improved firearms. By the 1880s, the machine gun had become an effective battlefield weapon. This technology gave European armies an advantage over their opponents, as armies in less-developed countries were still fighting with arrows, swords, and leather shields (e.g. the Zulus in Southern Africa during the Anglo-Zulu War of 1879).
