Problem: Anti-aircraft warfare:

Larger SAMs may be deployed in fixed launchers, but can be towed/re-deployed at will. The SAMs launched by individuals are known in the United States as the Man-Portable Air Defence Systems (MANPADS). MANPADS of the former Soviet Union have been exported around the World, and can be found in use by many armed forces. Targets for non-ManPAD SAMs will usually be acquired by air-search radar, then tracked before/while a SAM is "locked-on" and then fired. Potential targets, if they are military aircraft, will be identified as friend or foe before being engaged. The developments in the latest and relatively cheap short-range missiles have begun to replace autocannons in this role.

Short range missiles are replacing what weapons?
---
A: autocannons


Problem: An analysis of the evolution of mass media in the US and Europe since World War II noted mixed results from the growth of the Internet: "The digital revolution has been good for freedom of expression [and] information [but] has had mixed effects on freedom of the press": It has disrupted traditional sources of funding, and new forms of Internet journalism have replaced only a tiny fraction of what's been lost.
What did the analysis show mixed results for?
---
Answer: growth of the Internet


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Nasser's nomination for the post and the new constitution were put to public referendum on 23 June and each was approved by an overwhelming majority. A 350-member National Assembly was established, elections for which were held in July 1957. Nasser had ultimate approval over all the candidates. The constitution granted women's suffrage, prohibited gender-based discrimination, and entailed special protection for women in the workplace. Coinciding with the new constitution and Nasser's presidency, the RCC dissolved itself and its members resigned their military commissions as part of the transition to civilian rule. During the deliberations surrounding the establishment of a new government, Nasser began a process of sidelining his rivals among the original Free Officers, while elevating his closest allies to high-ranking positions in the cabinet.
Who could approve or reject candidates for the National Assembly?
A: Nasser


Context and question: Solar radiation is absorbed by the Earth's land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived.
What is the process by which green plants convert solar energy to stored energy?
Answer: photosynthesis


Question: In the first decades of the 19th century, Federal architecture and Greek Revival architecture were dominated by Philadelphia architects such as Benjamin Latrobe, William Strickland, John Haviland, John Notman, Thomas U. Walter, and Samuel Sloan. Frank Furness is considered Philadelphia's greatest architect of the second half of the 19th century, but his contemporaries included John McArthur, Jr., Addison Hutton, Wilson Eyre, the Wilson Brothers, and Horace Trumbauer. In 1871, construction began on the Second Empire-style Philadelphia City Hall. The Philadelphia Historical Commission was created in 1955 to preserve the cultural and architectural history of the city. The commission maintains the Philadelphia Register of Historic Places, adding historic buildings, structures, sites, objects and districts as it sees fit.
Is there an answer to this question: What does this commission control?

Answer: Philadelphia Register of Historic Places


Question: Economic and political migrations made an impact across the empire. For example, the Russian and Austria-Habsburg annexation of the Crimean and Balkan regions respectively saw large influxes of Muslim refugees – 200,000 Crimean Tartars fleeing to Dobruja. Between 1783 and 1913, approximately 5–7 million refugees flooded into the Ottoman Empire, at least 3.8 million of whom were from Russia. Some migrations left indelible marks such as political tension between parts of the empire (e.g. Turkey and Bulgaria) whereas centrifugal effects were noticed in other territories, simpler demographics emerging from diverse populations. Economies were also impacted with the loss of artisans, merchants, manufacturers and agriculturists. Since the 19th century, a large proportion of Muslim peoples from the Balkans emigrated to present-day Turkey. These people are called Muhacir. By the time the Ottoman Empire came to an end in 1922, half of the urban population of Turkey was descended from Muslim refugees from Russia.
Is there an answer to this question: What are the people from the Balkans who emigrated to Turkey called?

Answer:
Muhacir
