Q: The U.S. Institute of Medicine (IOM) updated Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for iron in 2001. The current EAR for iron for women ages 1418 is 7.9 mg/day, 8.1 for ages 1950 and 5.0 thereafter (post menopause). For men the EAR is 6.0 mg/day for ages 19 and up. The RDA is 15.0 mg/day for women ages 1518, 18.0 for 1950 and 8.0 thereafter. For men, 8.0 mg/day for ages 19 and up. RDAs are higher than EARs so as to identify amounts that will cover people with higher than average requirements. RDA for pregnancy is 27 mg/day and, for lactation, 9 mg/day. For children ages 13 years 7 mg/day, 10 for ages 48 and 8 for ages 913. As for safety, the IOM also sets Tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient. In the case of iron the UL is set at 45 mg/day. Collectively the EARs, RDAs and ULs are referred to as Dietary Reference Intakes.
Which age group within children is the RDA the highest?
A: ages 48

Q: The Ganges basin supports major fisheries, but these have declined in recent decades. In the Allahabad region in the middle section of the basin, catches of carp fell from 424.91 metric tons in 19611968 to 38.58 metric tons in 20012006, and catches of catfish fell from 201.35 metric tons in 19611968 to 40.56 metric tons in 20012006. In the Patna region in the lower section of the basin, catches of carp fell from 383.2 metric tons to 118, and catfish from 373.8 metric tons to 194.48. Some of the fish commonly caught in fisheries include catla (Catla catla), golden mahseer (Tor putitora), tor mahseer (Tor tor), rohu (Labeo rohita), walking catfish (Clarias batrachus), pangas catfish (Pangasius pangasius), Bagarius (Bagarius), Snakehead (fish) (Channa), bronze featherback (Notopterus notopterus) and milkfish (Chanos chanos).
Were more fish caught in the Patna region or the Allahabad region in the most recent numbers?
A: Patna

Q: By the time Colorado became a state on August 1, 1876, it had only 26 counties. In January 1877, Routt and Ouray were formed, followed by Gunnison and Custer counties in March. In February 1879, Chaffee County was created. From February 810, 1879, Lake county was renamed Carbonate County. In 1881, Dolores County and Pitkin County were created. In 1883, Montrose, Mesa, Garfield, Eagle, Delta, and San Miguel counties were formed, leaving the total number of counties at 39. The number rose to 40 in 1885 with the creation of Archuleta County on April 14. Washington County and Logan County were both created in 1887. Between February 19 and April 16 in 1889, Morgan, Yuma, Cheyenne, Otero, Rio Blanco, Phillips, Sedgwick, Kiowa, Kit Carson, Lincoln, Prowers, Baca, and Montezuma counties were formed, bringing the total to 55. By 1900, Mineral County and Teller County had been added. On November 15, 1902, Arapahoe County split into Adams in the north and Denver was recognized as a consolidated city-county. By 1912, Jackson County, Moffat County, and Crowley County had been created. Alamosa was created in 1913, and in 2001, Broomfield was recognized as a city-county, bringing the total to 64 counties.
In which year were the most counties added?
A: 1889

Q: Statistics on freight are specified in terms of the weight of freight lifted, and the net tonne kilometre, being freight weight multiplied by distance carried. 116.6 million tonnes of freight was lifted in the 20134 period, against 138 million tonnes in 19867, a decrease of 16%. However, a record 22.7 billion net tonne kilometres (14 billion net ton miles) of freight movement were recorded in 2013-4, against 16.6 billion (10.1 billion) in 19867, an increase of 38%. Coal makes up 36% of the total net tonne kilometre, though its share is declining. Rail freight has increased its market share since privatisation (by net tonne kilometres) from 7.4% in 1998 to 11.1% in 2013. Recent growth is partly due to more international services including the Channel Tunnel and Port of Felixstowe, which is containerised. Nevertheless, network bottlenecks and insufficient investment in catering for 9 6" high shipping containers restrict growth.
How many more billion net ton miles of freight movement more was recorded in 2013-14 than in 1986-7?
A:
3.9
