Question: Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.
Try to answer this question if possible: What is the lowest level of sensitivity, in micrometers, for InGaAs?
Answer: 950
Question: Other critics, such as Francis Fukuyama, note that "terrorism" is not an enemy, but a tactic; calling it a "war on terror", obscures differences between conflicts such as anti-occupation insurgents and international mujahideen. With a military presence in Iraq and Afghanistan and its associated collateral damage Shirley Williams maintains this increases resentment and terrorist threats against the West. There is also perceived U.S. hypocrisy, media-induced hysteria, and that differences in foreign and security policy have damaged America's image in most of the world.
Try to answer this question if possible: Who said the US's presence in Iraq increases resentment and terrorists?
Answer: Shirley Williams
Question: Traditional willow growing and weaving (such as basket weaving) is not as extensive as it used to be but is still carried out on the Somerset Levels and is commemorated at the Willows and Wetlands Visitor Centre. Fragments of willow basket were found near the Glastonbury Lake Village, and it was also used in the construction of several Iron Age causeways. The willow was harvested using a traditional method of pollarding, where a tree would be cut back to the main stem. During the 1930s more than 3,600 hectares (8,900 acres) of willow were being grown commercially on the Levels. Largely due to the displacement of baskets with plastic bags and cardboard boxes, the industry has severely declined since the 1950s. By the end of the 20th century only about 140 hectares (350 acres) were grown commercially, near the villages of Burrowbridge, Westonzoyland and North Curry. The Somerset Levels is now the only area in the UK where basket willow is grown commercially.
Try to answer this question if possible: In what decade was the Willows and Wetlands Visitor Centre established?
Answer: unanswerable
Question: In 1975 the US DOT conservatively identified a 0.7% reduction in traffic fatalities during DST, and estimated the real reduction at 1.5% to 2%, but the 1976 NBS review of the DOT study found no differences in traffic fatalities. In 1995 the Insurance Institute for Highway Safety estimated a reduction of 1.2%, including a 5% reduction in crashes fatal to pedestrians. Others have found similar reductions. Single/Double Summer Time (SDST), a variant where clocks are one hour ahead of the sun in winter and two in summer, has been projected to reduce traffic fatalities by 3% to 4% in the UK, compared to ordinary DST. However, accidents do increase by as much as 11% during the two weeks that follow the end of British Summer Time. It is not clear whether sleep disruption contributes to fatal accidents immediately after the spring clock shifts. A correlation between clock shifts and traffic accidents has been observed in North America and the UK but not in Finland or Sweden. If this effect exists, it is far smaller than the overall reduction in traffic fatalities. A 2009 US study found that on Mondays after the switch to DST, workers sleep an average of 40 minutes less, and are injured at work more often and more severely.
Try to answer this question if possible: How much less, on average, do workers in the U.S. sleep on Mondays after switching to DST, according to the 2009 study?
Answer:
40 minutes
