The problem: Answer a question about this article:
Early research into circadian rhythms suggested that most people preferred a day closer to 25 hours when isolated from external stimuli like daylight and timekeeping. However, this research was faulty because it failed to shield the participants from artificial light. Although subjects were shielded from time cues (like clocks) and daylight, the researchers were not aware of the phase-delaying effects of indoor electric lights.[dubious – discuss] The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep. Electric light in the evening delayed their circadian phase.[citation needed] A more stringent study conducted in 1999 by Harvard University estimated the natural human rhythm to be closer to 24 hours, 11 minutes: much closer to the solar day but still not perfectly in sync.
What was the fault not considered in the early theories of day length?
****
The answer: artificial light

Problem: Because the actions involved in the "war on terrorism" are diffuse, and the criteria for inclusion are unclear, political theorist Richard Jackson has argued that "the 'war on terrorism' therefore, is simultaneously a set of actual practices—wars, covert operations, agencies, and institutions—and an accompanying series of assumptions, beliefs, justifications, and narratives—it is an entire language or discourse." Jackson cites among many examples a statement by John Ashcroft that "the attacks of September 11 drew a bright line of demarcation between the civil and the savage". Administration officials also described "terrorists" as hateful, treacherous, barbarous, mad, twisted, perverted, without faith, parasitical, inhuman, and, most commonly, evil. Americans, in contrast, were described as brave, loving, generous, strong, resourceful, heroic, and respectful of human rights.
Who said the 'war on terrorism' is 'an entire language of discourse'?
The answer is the following: Richard Jackson
