Question: "What is not a means of transportation for flightless birds?" Context: "Most birds can fly, which distinguishes them from almost all other vertebrate classes. Flight is the primary means of locomotion for most bird species and is used for breeding, feeding, and predator avoidance and escape. Birds have various adaptations for flight, including a lightweight skeleton, two large flight muscles, the pectoralis (which accounts for 15% of the total mass of the bird) and the supracoracoideus, as well as a modified forelimb (wing) that serves as an aerofoil. Wing shape and size generally determine a bird species' type of flight; many birds combine powered, flapping flight with less energy-intensive soaring flight. About 60 extant bird species are flightless, as were many extinct birds. Flightlessness often arises in birds on isolated islands, probably due to limited resources and the absence of land predators. Though flightless, penguins use similar musculature and movements to "fly" through the water, as do auks, shearwaters and dippers." Answer:
----
Answer: Flight

Q: Question: "What dates mentioned precedes 1723 in the text" Context: "The fortified city temporarily fell to the French invasion in 1672 (the Disaster Year); where the French invasion was only stopped west of Utrecht at the Old Hollandic Waterline. In 1674, only two years after the French left, the centre of Utrecht was struck by a tornado. The halt to building before construction of flying buttresses in the 15th century now proved to be the undoing of the central section of the cathedral of St Martin church which collapsed; creating the current Dom square between the tower and choir. In 1713, Utrecht hosted one of the first international peace negotiations when the Treaty of Utrecht settled the War of the Spanish Succession. Since 1723 Utrecht became the centre of the non-Roman Old Catholic Churches in the world." Answer:
A: 1713

Question: Question: "How are pasteurization and autoclavation different from other food safety technologies?" Context: "Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature. Cooling is the primary technology used to maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation, autoclavation, drying, salting, and separation of various components, all of which appearing to alter the original nutritional contents of food. Pasteurisation and autoclavation (heating techniques) have no doubt improved the safety of many common foods, preventing epidemics of bacterial infection. But some of the (new) food processing technologies have downfalls as well." Answer:
Answer: heating

Please answer this: Question: "Why do countries like the US, Russian, and countries of the EU feel the need to intervene and help?" Context: "Drug trafficking is the major illegal source of income in Tajikistan as it is an important transit country for Afghan narcotics bound for Russian and, to a lesser extent, Western European markets; some opium poppy is also raised locally for the domestic market. However, with the increasing assistance from international organizations, such as UNODC, and cooperation with the US, Russian, EU and Afghan authorities a level of progress on the fight against illegal drug-trafficking is being achieved. Tajikistan holds third place in the world for heroin and raw opium confiscations (1216.3 kg of heroin and 267.8 kg of raw opium in the first half of 2006). Drug money corrupts the country's government; according to some experts the well-known personalities that fought on both sides of the civil war and have held the positions in the government after the armistice was signed are now involved in the drug trade. UNODC is working with Tajikistan to strengthen border crossings, provide training, and set up joint interdiction teams. It also helped to establish Tajikistani Drug Control Agency." Answer:
++++++++

Tajikistan holds third place in the world for heroin and raw opium confiscations
