Problem: Political corruption:

Forms of corruption vary, but include bribery, extortion, cronyism, nepotism, gombeenism, parochialism patronage, influence peddling, graft, and embezzlement. Corruption may facilitate criminal enterprise such as drug trafficking, money laundering, and human trafficking, though is not restricted to these activities. Misuse of government power for other purposes, such as repression of political opponents and general police brutality, is also considered political corruption.

Three forms of corruption that can promote criminal activities include drugs, money laundering, and what?

A: human trafficking


Problem: In Darwin's time there was no agreed-upon model of heredity; in Chapter I Darwin admitted, "The laws governing inheritance are quite unknown." He accepted a version of the inheritance of acquired characteristics (which after Darwin's death came to be called Lamarckism), and Chapter V discusses what he called the effects of use and disuse; he wrote that he thought "there can be little doubt that use in our domestic animals strengthens and enlarges certain parts, and disuse diminishes them; and that such modifications are inherited", and that this also applied in nature. Darwin stated that some changes that were commonly attributed to use and disuse, such as the loss of functional wings in some island dwelling insects, might be produced by natural selection. In later editions of Origin, Darwin expanded the role attributed to the inheritance of acquired characteristics. Darwin also admitted ignorance of the source of inheritable variations, but speculated they might be produced by environmental factors. However, one thing was clear: whatever the exact nature and causes of new variations, Darwin knew from observation and experiment that breeders were able to select such variations and produce huge differences in many generations of selection. The observation that selection works in domestic animals is not destroyed by lack of understanding of the underlying hereditary mechanism.
What did Darwin speculate might be how inheritable variations might come about in a species?

Answer: environmental factors


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On March 23, 2011, the CRTC rejected an application by the CBC to install a digital transmitter serving Fredricton, New Brunswick in place of the analogue transmitter serving Fredericton and Saint John, New Brunswick, which would have served only 62.5% of the population served by the existing analogue transmitter. The CBC issued a press release stating "CBC/Radio-Canada intends to re-file its application with the CRTC to provide more detailed cost estimates that will allow the Commission to better understand the unfeasibility of replicating the Corporation’s current analogue coverage." The press release further added that the CBC suggests coverage could be maintained if the CRTC were to "allow CBC Television to continue providing the analogue service it offers today – much in the same way the Commission permitted recently in the case of Yellowknife, Whitehorse and Iqaluit."
The CRTC required that all conversions serve at least what percent of the population?
A: unanswerable


Context and question: The Queensboro Bridge is an important piece of cantilever architecture. The Manhattan Bridge, Throgs Neck Bridge, Triborough Bridge, and Verrazano-Narrows Bridge are all examples of Structural Expressionism.
The Queensboro Bridge utilized what type of construction?
Answer: cantilever


Question: Though almost any variety of acoustic mandolin might be adequate for Irish traditional music, virtually all Irish players prefer flat-backed instruments with oval sound holes to the Italian-style bowl-back mandolins or the carved-top mandolins with f-holes favoured by bluegrass mandolinists. The former are often too soft-toned to hold their own in a session (as well as having a tendency to not stay in place on the player's lap), whilst the latter tend to sound harsh and overbearing to the traditional ear. The f-hole mandolin, however, does come into its own in a traditional session, where its brighter tone cuts through the sonic clutter of a pub. Greatly preferred for formal performance and recording are flat-topped "Irish-style" mandolins (reminiscent of the WWI-era Martin Army-Navy mandolin) and carved (arch) top mandolins with oval soundholes, such as the Gibson A-style of the 1920s.
Is there an answer to this question:  Why is it said that the Italian style can hold their own session?

Answer: unanswerable


Problem: Group (mathematics):

Finite symmetry groups such as the Mathieu groups are used in coding theory, which is in turn applied in error correction of transmitted data, and in CD players. Another application is differential Galois theory, which characterizes functions having antiderivatives of a prescribed form, giving group-theoretic criteria for when solutions of certain differential equations are well-behaved.u[›] Geometric properties that remain stable under group actions are investigated in (geometric) invariant theory.

What is used for error correction of transferred data?
---
A:
coding theory
