Problem: Computer:

By the 1950s the success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remain in use in some specialized applications such as education (control systems) and aircraft (slide rule).

Analog computers remain in use in what industries?
---
A: education (control systems) and aircraft (slide rule).

Problem: Charleston, South Carolina:

Founded in 1670 as Charles Town in honor of King Charles II of England, Charleston adopted its present name in 1783. It moved to its present location on Oyster Point in 1680 from a location on the west bank of the Ashley River known as Albemarle Point. By 1690, Charles Town was the fifth-largest city in North America, and it remained among the 10 largest cities in the United States through the 1840 census. With a 2010 census population of 120,083 (and a 2014 estimate of 130,113), current trends put Charleston as the fastest-growing municipality in South Carolina. The population of the Charleston metropolitan area, comprising Berkeley, Charleston, and Dorchester Counties, was counted by the 2014 estimate at 727,689 the third-largest in the state and the 78th-largest metropolitan statistical area in the United States.

What year wasn't Charleston founded?

Problem: Infrared:

The concept of emissivity is important in understanding the infrared emissions of objects. This is a property of a surface that describes how its thermal emissions deviate from the ideal of a black body. To further explain, two objects at the same physical temperature will not show the same infrared image if they have differing emissivity. For example, for any pre-set emissivity value, objects with higher emissivity will appear hotter, and those with a lower emissivity will appear cooler. For that reason, incorrect selection of emissivity will give inaccurate results when using infrared cameras and pyrometers.

What ideal shows inaccurate results when using infrared cameras?
---
A: unanswerable

Problem: Somerset:

Somerset is a rural county of rolling hills such as the Blackdown Hills, Mendip Hills, Quantock Hills and Exmoor National Park, and large flat expanses of land including the Somerset Levels. There is evidence of human occupation from Paleolithic times, and of subsequent settlement in the Roman and Anglo-Saxon periods. The county played a significant part in the consolidation of power and rise of King Alfred the Great, and later in the English Civil War and the Monmouth Rebellion. The city of Bath is famous for its substantial Georgian architecture and is a UNESCO World Heritage Site.
