QUES: Since 1934, the sale of Federal Duck Stamps has generated $670 million, and helped to purchase or lease 5,200,000 acres (8,100 sq mi; 21,000 km2) of habitat. The stamps serve as a license to hunt migratory birds, an entrance pass for all National Wildlife Refuge areas, and are also considered collectors items often purchased for aesthetic reasons outside of the hunting and birding communities. Although non-hunters buy a significant number of Duck Stamps, eighty-seven percent of their sales are contributed by hunters, which is logical, as hunters are required to purchase them. Distribution of funds is managed by the Migratory Bird Conservation Commission (MBCC).
What percentage of hunters belong to the MBCC?

QUES: The George Washington Bridge is the world's busiest motor vehicle bridge, connecting Manhattan to Bergen County, New Jersey. The Verrazano-Narrows Bridge is the longest suspension bridge in the Americas and one of the world's longest. The Brooklyn Bridge is an icon of the city itself. The towers of the Brooklyn Bridge are built of limestone, granite, and Rosendale cement, and their architectural style is neo-Gothic, with characteristic pointed arches above the passageways through the stone towers. This bridge was also the longest suspension bridge in the world from its opening until 1903, and is the first steel-wire suspension bridge.
What style of architecture was used to design the Brooklyn Bridge?

ANS: neo-Gothic

QUES: Pesticides may cause acute and delayed health effects in people who are exposed. Pesticide exposure can cause a variety of adverse health effects, ranging from simple irritation of the skin and eyes to more severe effects such as affecting the nervous system, mimicking hormones causing reproductive problems, and also causing cancer. A 2007 systematic review found that "most studies on non-Hodgkin lymphoma and leukemia showed positive associations with pesticide exposure" and thus concluded that cosmetic use of pesticides should be decreased. There is substantial evidence of associations between organophosphate insecticide exposures and neurobehavioral alterations. Limited evidence also exists for other negative outcomes from pesticide exposure including neurological, birth defects, fetal death,
What system is mostly affected by non-Hodgkin lymphoma?

ANS: unanswerable

QUES: A squab is the name given to the young of domestic pigeons that are destined for the table. Like other domesticated pigeons, birds used for this purpose are descended from the rock pigeon (Columba livia). Special utility breeds with desirable characteristics are used. Two eggs are laid and incubated for about 17 days. When they hatch, the squabs are fed by both parents on "pigeon's milk", a thick secretion high in protein produced by the crop. Squabs grow rapidly, but are slow to fledge and are ready to leave the nest at 26 to 30 days weighing about 500 g (18 oz). By this time, the adult pigeons will have laid and be incubating another pair of eggs and a prolific pair should produce two squabs every four weeks during a breeding season lasting several months.
Why does the breeding season only last a few days?
