Article: In many non-US western countries a 'fourth hurdle' of cost effectiveness analysis has developed before new technologies can be provided. This focuses on the efficiency (in terms of the cost per QALY) of the technologies in question rather than their efficacy. In England and Wales NICE decides whether and in what circumstances drugs and technologies will be made available by the NHS, whilst similar arrangements exist with the Scottish Medicines Consortium in Scotland, and the Pharmaceutical Benefits Advisory Committee in Australia. A product must pass the threshold for cost-effectiveness if it is to be approved. Treatments must represent 'value for money' and a net benefit to society.

Question: What threshold must a drug pass before it is approved?
Ans: cost-effectiveness

Article: Except for the five species of monotremes (egg-laying mammals), all modern mammals give birth to live young. Most mammals, including the six most species-rich orders, belong to the placental group. The three largest orders in numbers, are first Rodentia: mice, rats, porcupines, beavers, capybaras, and other gnawing mammals; then Chiroptera: bats; and then Soricomorpha: shrews, moles and solenodons. The next three orders, depending on the biological classification scheme used, are the Primates including the humans; the Cetartiodactyla including the whales and the even-toed hoofed mammals; and the Carnivora, that is, cats, dogs, weasels, bears, seals, and their relatives.

Question: How many species of mammals do not have a live birth?
Ans: five species

Article: Near the intersection of Craycroft and Ft. Lowell Roads are the remnants of the Historic Fort Lowell. This area has become one of Tucson's iconic neighborhoods. In 1891, the Fort was abandoned and much of the interior was stripped of their useful components and it quickly fell into ruin. In 1900, three of the officer buildings were purchased for use as a sanitarium. The sanitarium was then sold to Harvey Adkins in 1928. The Bolsius family Pete, Nan and Charles Bolsius purchased and renovated surviving adobe buildings of the Fort transforming them into spectacular artistic southwestern architectural examples. Their woodwork, plaster treatment and sense of proportion drew on their Dutch heritage and New Mexican experience. Other artists and academics throughout the middle of the 20th century, including: Win Ellis, Jack Maul, Madame Cheruy, Giorgio Belloli, Charels Bode, Veronica Hughart, Edward and Rosamond Spicer, Hazel Larson Archer and Ruth Brown, renovated adobes, built homes and lived in the area. The artist colony attracted writers and poets including beat generation Alan Harrington and Jack Kerouac whose visit is documented in his iconic book On the Road. This rural pocket in the middle of the city is listed on the National Register of Historic Places. Each year in February the neighborhood celebrates its history in the City Landmark it owns and restored the San Pedro Chapel.

Question: When was Fort Lowell shut down?
Ans:
1891
