Problem: Montana:

In 1940, Jeannette Rankin had once again been elected to Congress, and in 1941, as she did in 1917, she voted against the United States' declaration of war. This time she was the only vote against the war, and in the wake of public outcry over her vote, she required police protection for a time. Other pacifists tended to be those from "peace churches" who generally opposed war. Many individuals from throughout the U.S. who claimed conscientious objector status were sent to Montana during the war as smokejumpers and for other forest fire-fighting duties.

What were conscientious objectors sent to Montana to do?
---
A: smokejumpers and for other forest fire-fighting duties.

Problem: Most common glass contains other ingredients to change its properties. Lead glass or flint glass is more 'brilliant' because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eyeglasses.[citation needed] Iron can be incorporated into glass to absorb infrared energy, for example in heat absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs UV wavelengths.
What is another name for lead glass?

Answer: flint glass

Portugal has arguably the most liberal laws concerning possession of illicit drugs in the Western world. In 2001, Portugal decriminalized possession of effectively all drugs that are still illegal in other developed nations including, but not limited to, cannabis, cocaine, heroin, and LSD. While possession is legal, trafficking and possession of more than "10 days worth of personal use" are still punishable by jail time and fines. People caught with small amounts of any drug are given the choice to go to a rehab facility, and may refuse treatment without consequences. Despite criticism from other European nations, who stated Portugal's drug consumption would tremendously increase, overall drug use has declined along with the number of HIV infection cases, which had dropped 50 percent by 2009. Drug use among 16- to 18-year-olds also declined, however the use of marijuana rose only slightly among that age group.
By 2009, by how much had the rate of HIV infection decreased?
A: 50 percent

Context and question: Some Europeans living among Indigenous Americans were called "white Indians". They "lived in native communities for years, learned native languages fluently, attended native councils, and often fought alongside their native companions." More numerous and typical were traders and trappers, who married Indigenous American women from tribes on the frontier and had families with them. Some traders, who kept bases in the cities, had what ware called "country wives" among Indigenous Americans, with legal European-American wives and children at home in the city. Not all abandoned their "natural" mixed-race children. Some arranged for sons to be sent to European-American schools for their education.
Who lived in native communities, speaking the language and participating in the affairs of tribes?

Question: The physical relief of the island is dominated by two mountain ranges, the Troodos Mountains and the smaller Kyrenia Range, and the central plain they encompass, the Mesaoria. The Mesaoria plain is drained by the Pedieos River, the longest on the island. The Troodos Mountains cover most of the southern and western portions of the island and account for roughly half its area. The highest point on Cyprus is Mount Olympus at 1,952 m (6,404 ft), located in the centre of the Troodos range. The narrow Kyrenia Range, extending along the northern coastline, occupies substantially less area, and elevations are lower, reaching a maximum of 1,024 m (3,360 ft). The island lies within the Anatolian Plate.
Is there an answer to this question: What plain is located in between the Troodos Mountains and the Kyrenia Range?

Answer: the Mesaoria

Question: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
