Q: Extract the answer to the question from the following context. Question: Other than expenses, what makes TB treatment inconvenient for those receiving it? Context: Tuberculosis is the second-most common cause of death from infectious disease (after those due to HIV/AIDS). The total number of tuberculosis cases has been decreasing since 2005, while new cases have decreased since 2002. China has achieved particularly dramatic progress, with about an 80% reduction in its TB mortality rate between 1990 and 2010. The number of new cases has declined by 17% between 20042014. Tuberculosis is more common in developing countries; about 80% of the population in many Asian and African countries test positive in tuberculin tests, while only 510% of the US population test positive. Hopes of totally controlling the disease have been dramatically dampened because of a number of factors, including the difficulty of developing an effective vaccine, the expensive and time-consuming diagnostic process, the necessity of many months of treatment, the increase in HIV-associated tuberculosis, and the emergence of drug-resistant cases in the 1980s.
A: time-consuming diagnostic process, the necessity of many months of treatment

Q: Extract the answer to the question from the following context. Question: What happened after 1974 that impacted Portugal's economy? Context: Since the Carnation Revolution of 1974, which culminated in the end of one of Portugal's most notable phases of economic expansion (that started in the 1960s), a significant change has occurred in the nation's annual economic growth.[citation needed] After the turmoil of the 1974 revolution and the PREC period, Portugal tried to adapt to a changing modern global economy, a process that continues in 2013. Since the 1990s, Portugal's public consumption-based economic development model has been slowly changing to a system that is focused on exports, private investment and the development of the high-tech sector. Consequently, business services have overtaken more traditional industries such as textiles, clothing, footwear and cork (Portugal is the world's leading cork producer), wood products and beverages.
A: PREC period

Q: Extract the answer to the question from the following context. Question: What does the P in "MANPADS" stand for? Context: NATO defines anti-aircraft warfare (AAW) as "measures taken to defend a maritime force against attacks by airborne weapons launched from aircraft, ships, submarines and land-based sites." In some armies the term All-Arms Air Defence (AAAD) is used for air defence by non-specialist troops. Other terms from the late 20th century include GBAD (Ground Based AD) with related terms SHORAD (Short Range AD) and MANPADS ("Man Portable AD Systems": typically shoulder-launched missiles). Anti-aircraft missiles are variously called surface-to-air missile, abbreviated and pronounced "SAM" and Surface to Air Guided Weapon (SAGW).
A: Portable

Q: Extract the answer to the question from the following context. Question: What is the word used to describe a metal that is found not as an ore? Context: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.
