The problem: Answer a question about this article:
Traditionally, subspecies are seen as geographically isolated and genetically differentiated populations. That is, "the designation 'subspecies' is used to indicate an objective degree of microevolutionary divergence" One objection to this idea is that it does not specify what degree of differentiation is required. Therefore, any population that is somewhat biologically different could be considered a subspecies, even to the level of a local population. As a result, Templeton has argued that it is necessary to impose a threshold on the level of difference that is required for a population to be designated a subspecies.
What would a population have to somewhat be to be considered a subspecies?
****
The answer: biologically different


Problem: Please answer a question about the following article about Hokkien:
In general, Hokkien dialects have 5 to 7 phonemic tones. According to the traditional Chinese system, however, there are 7 to 9 "tones",[citation needed] more correctly termed tone classes since two of them are non-phonemic "entering tones" (see the discussion on Chinese tone). Tone sandhi is extensive. There are minor variations between the Quanzhou and Zhangzhou tone systems. Taiwanese tones follow the patterns of Amoy or Quanzhou, depending on the area of Taiwan. Many dialects have an additional phonemic tone ("tone 9" according to the traditional reckoning), used only in special or foreign loan words.
How many phonemic tones do Hokkien dialects have?
A: 5 to 7

On 14 January 1858, an Italian refugee from Britain called Orsini attempted to assassinate Napoleon III with a bomb made in England. The ensuing diplomatic crisis destabilised the government, and Palmerston resigned. Derby was reinstated as prime minister. Victoria and Albert attended the opening of a new basin at the French military port of Cherbourg on 5 August 1858, in an attempt by Napoleon III to reassure Britain that his military preparations were directed elsewhere. On her return Victoria wrote to Derby reprimanding him for the poor state of the Royal Navy in comparison to the French one. Derby's ministry did not last long, and in June 1859 Victoria recalled Palmerston to office.
