Question: While Paris has some of the richest neighbourhoods in France, it also has some of the poorest, mostly on the eastern side of the city. In 2012, 14 percent of households in the city earned less than 977 per month, the official poverty line. Twenty-five percent of residents in the 19th arrondissement lived below the poverty line; 24 percent in the 18th, 22 percent in the 20th and 18 percent in the 10th. In the city's wealthiest neighbourhood, the 7th arrondissement, 7 percent lived below the poverty line; 8 percent in the 6th arrondissement; and 9 percent in the 16th arrondissement.
Is there an answer to this question: What percentage of people lived below the poverty line in Paris' wealthiest neighborhood?

Answer: 7

Question: Post-war, Devonport Dockyard was kept busy refitting aircraft carriers such as the Ark Royal and, later, nuclear submarines while new light industrial factories were constructed in the newly zoned industrial sector attracting rapid growth of the urban population. The army had substantially left the city by 1971, with barracks pulled down in the 1960s, however the city remains home to the 42 Commando of the Royal Marines.
Is there an answer to this question: What military unit is based in Plymouth?

Answer: 42 Commando of the Royal Marines

Question: A number of studies have reported associations between pathogen load in an area and human behavior. Higher pathogen load is associated with decreased size of ethnic and religious groups in an area. This may be due high pathogen load favoring avoidance of other groups, which may reduce pathogen transmission, or a high pathogen load preventing the creation of large settlements and armies that enforce a common culture. Higher pathogen load is also associated with more restricted sexual behavior, which may reduce pathogen transmission. It also associated with higher preferences for health and attractiveness in mates. Higher fertility rates and shorter or less parental care per child is another association that may be a compensation for the higher mortality rate. There is also an association with polygyny which may be due to higher pathogen load, making selecting males with a high genetic resistance increasingly important. Higher pathogen load is also associated with more collectivism and less individualism, which may limit contacts with outside groups and infections. There are alternative explanations for at least some of the associations although some of these explanations may in turn ultimately be due to pathogen load. Thus, polygny may also be due to a lower male:female ratio in these areas but this may ultimately be due to male infants having increased mortality from infectious diseases. Another example is that poor socioeconomic factors may ultimately in part be due to high pathogen load preventing economic development.
Is there an answer to this question: What is the only cause of poor socioeconomic factors?

Answer: unanswerable

Question: Logically, no number of positive outcomes at the level of experimental testing can confirm a scientific theory, but a single counterexample is logically decisive: it shows the theory, from which the implication is derived, to be false. To say that a given statement (e.g., the statement of a law of some scientific theory) -- [call it "T"] -- is "falsifiable" does not mean that "T" is false. Rather, it means that, if "T" is false, then (in principle), "T" could be shown to be false, by observation or by experiment. Popper's account of the logical asymmetry between verification and falsifiability lies at the heart of his philosophy of science. It also inspired him to take falsifiability as his criterion of demarcation between what is, and is not, genuinely scientific: a theory should be considered scientific if, and only if, it is falsifiable. This led him to attack the claims of both psychoanalysis and contemporary Marxism to scientific status, on the basis that their theories are not falsifiable.
Is there an answer to this question: What does Popper say demarcates scientific theory from non-science?

Answer:
falsifiability
