Problem: Mali:

Mali faces numerous health challenges related to poverty, malnutrition, and inadequate hygiene and sanitation. Mali's health and development indicators rank among the worst in the world. Life expectancy at birth is estimated to be 53.06 years in 2012. In 2000, 62–65 percent of the population was estimated to have access to safe drinking water and only 69 percent to sanitation services of some kind. In 2001, the general government expenditures on health totalled about US$4 per capita at an average exchange rate.

In 2000 what percentage of the population had access to safe drinking water?

A: 62–65


Problem: During the Risorgimento, proponents of Italian republicanism and Italian nationalism, such as Alessandro Manzoni, stressed the importance of establishing a uniform national language in order to better create an Italian national identity. With the unification of Italy in the 1860s, standard Italian became the official national language of the new Italian state, while the various unofficial regional languages of Italy gradually became regarded as subordinate "dialects" to Italian, increasingly associated negatively with lack of education or provincialism. However, at the time of the Italian Unification, standard Italian still existed mainly as a literary language, and only 2.5% of Italy's population could speak standard Italian.
When did Risorgimento become the official language of the new Italian state?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the United States, the term "the 51st state" when applied to Canada can serve to highlight the similarities and close relationship between the United States and Canada. Sometimes the term is used disparagingly, intended to deride Canada as an unimportant neighbor. In the Quebec general election, 1989, the political party Parti 51 ran 11 candidates on a platform of Quebec seceding from Canada to join the United States (with its leader, André Perron, claiming Quebec could not survive as an independent nation). The party attracted just 3,846 votes across the province, 0.11% of the total votes cast. In comparison, the other parties in favour of sovereignty of Quebec in that election got 40.16% (PQ) and 1.22% (NPDQ).
What is a negative connotation of Andre Perron?
A: unanswerable


Context and question: Railways must operate at variable speeds. Until the mid 1980s this was only practical with the brush-type DC motor, although such DC can be supplied from an AC catenary via on-board electric power conversion. Since such conversion was not well developed in the late 19th century and early 20th century, most early electrified railways used DC and many still do, particularly rapid transit (subways) and trams. Speed was controlled by connecting the traction motors in various series-parallel combinations, by varying the traction motors' fields, and by inserting and removing starting resistances to limit motor current.
What are two types of railway transportation still use DC motor?
Answer: rapid transit (subways) and trams


Question: Typically, the warmest day of the year (1971–2000) will achieve a temperature of 26.6 °C (80 °F), although in June 1976 the temperature reached 31.6 °C (89 °F), the site record. On average, 4.25 days of the year will report a maximum temperature of 25.1 °C (77 °F) or above. During the winter half of the year, the coldest night will typically fall to −4.1 °C (25 °F) although in January 1979 the temperature fell to −8.8 °C (16 °F). Typically, 18.6 nights of the year will register an air frost.
Is there an answer to this question: In what month and year did Plymouth see its highest temperature between 1971 and 2000?

Answer: June 1976

If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where is Emosson located?
Ah, so..
Valais, Switzerland
