Article: Zinc metal is produced using extractive metallurgy. After grinding the ore, froth flotation, which selectively separates minerals from gangue by taking advantage of differences in their hydrophobicity, is used to get an ore concentrate. This concentrate consists of about 50% zinc with the rest being sulfur (32%), iron (13%), and SiO
2 (5%). The composition of this is normally zinc sulfide (80% to 85%), iron sulfide (7.0% to 12%), lead sulfide (3.0% to 5.0%) silica (2.5% to 3.5%), and cadmium sulfide (0.35% to 0.41%).

Question: What percentage of the ore concentrate is zinc?
Ans: 50%


Article: In the early 1900s, James J. Hill of the Great Northern began promoting settlement in the Montana prairie to fill his trains with settlers and goods. Other railroads followed suit. In 1902, the Reclamation Act was passed, allowing irrigation projects to be built in Montana's eastern river valleys. In 1909, Congress passed the Enlarged Homestead Act that expanded the amount of free land from 160 to 320 acres (0.6 to 1.3 km2) per family and in 1912 reduced the time to "prove up" on a claim to three years. In 1916, the Stock-Raising Homestead Act allowed homesteads of 640 acres in areas unsuitable for irrigation.  This combination of advertising and changes in the Homestead Act drew tens of thousands of homesteaders, lured by free land, with World War I bringing particularly high wheat prices. In addition, Montana was going through a temporary period of higher-than-average precipitation. Homesteaders arriving in this period were known as "Honyockers", or "scissorbills." Though the word "honyocker", possibly derived from the ethnic slur "hunyak," was applied in a derisive manner at homesteaders as being "greenhorns", "new at his business" or "unprepared", the reality was that a majority of these new settlers had previous farming experience, though there were also many who did not.

Question: In what year was the Reclamation Act passed?
Ans: 1902


Article: Public expenditure health was at 8.9% of the GDP in 2004, whereas private expenditure was at 1.3%. As of 2012, the HIV/AIDS prevalence was at 2.8% among 15- to 49-year-olds. Health expenditure was at US$30 per capita in 2004. A large proportion of the population is undernourished, with malnutrition being a problem in Congo-Brazzaville. There were 20 physicians per 100,000 persons in the early 2000s (decade).

Question: How much was spent per capita on health in 2004 as measured in US dollars?
Ans:
$30
