Please answer this: Extract the answer to the question from the following context. Question: Jannsen, Hurt, and Jakobson all shared in the what culture? Context: As a result of the abolition of serfdom and the availability of education to the native Estonian-speaking population, an active Estonian nationalist movement developed in the 19th century.[citation needed] It began on a cultural level, resulting in the establishment of Estonian language literature, theatre and professional music and led on to the formation of the Estonian national identity and the Age of Awakening. Among the leaders of the movement were Johann Voldemar Jannsen, Jakob Hurt and Carl Robert Jakobson.

Problem: Extract the answer to the question from the following context. Question: Which of the following cannot be endangered: Fauna, Fish or President Richard Nixon? Context: The Endangered Species Act of 1973 (ESA; 16 U.S.C. 1531 et seq.) is one of the few dozens of United States environmental laws passed in the 1970s, and serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The ESA was signed into law by President Richard Nixon on December 28, 1973, it was designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation." The U.S. Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration (NOAA).

A: President Richard Nixon

Problem: Given the question: Extract the answer to the question from the following context. Question: How does bike sharing work? Context: The local government continuously strives for a reduction of massive traffic congestion, and has increased incentives for making a bicycle-friendly city. This includes North America's second-largest bicycle sharing system, EcoBici, launched in 2010, in which registered residents can get bicycles for 45 minutes with a pre-paid subscription of 300 pesos a year. There are, as of September 2013, 276 stations with 4,000 bicycles across an area stretching from the Historic center to Polanco. within 300 metres (980 feet) of one another and are fully automatic using a transponder based card. Bicycle-service users have access to several permanent Ciclovias (dedicated bike paths/lanes/streets), including ones along Paseo de la Reforma and Avenida Chapultepec as well as one running 59 kilometres (37 miles) from Polanco to Fierro del Toro, which is located south of Cumbres del Ajusco National Park, near the Morelos state line. The city's initiative is inspired by forward thinking examples, such as Denmark's Copenhagenization.

input question: Extract the answer to the question from the following context. Question: What was found at Mount Batten? Context: Upper Palaeolithic deposits, including bones of Homo sapiens, have been found in local caves, and artefacts dating from the Bronze Age to the Middle Iron Age have been found at Mount Batten showing that it was one of the main trading ports of the country at that time. An unidentified settlement named 'TAMARI OSTIA' (mouth/estuaries of the Tamar) is listed in Ptolemy's Geographia and is presumed to be located in the area of the modern city.???

Extract the answer to the question from the following context. Question: What type of transportation system sometimes uses DC power? Context: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.

Q: Extract the answer to the question from the following context. Question: Pub windows recently became different from how they were, which was? Context: Historically, pubs have been socially and culturally distinct from cafes, bars and German beer halls. Most pubs offer a range of beers, wines, spirits, and soft drinks and snacks. Traditionally the windows of town pubs were of smoked or frosted glass to obscure the clientele from the street but from the 1990s onwards, there has been a move towards clear glass, in keeping with brighter interiors.
A:
smoked or frosted glass
