Input: Read this: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Question: What measures 17,968 square miles?

Output: unanswerable

QUES: Charleston is the oldest and second-largest city in the U.S. state of South Carolina, the county seat of Charleston County, and the principal city in the CharlestonNorth CharlestonSummerville Metropolitan Statistical Area. The city lies just south of the geographical midpoint of South Carolina's coastline and is located on Charleston Harbor, an inlet of the Atlantic Ocean formed by the confluence of the Ashley and Cooper Rivers, or, as is locally expressed, "where the Cooper and Ashley Rivers come together to form the Atlantic Ocean."

What river mergers with the Cooper River to form Charleston Harbor?
What is the answer?
ANS: Ashley Rivers

QUES: Around the sixth century AD, a tribe of Slavs arrived in a portion of Central Europe. According to legend they were led by a hero named Cech, from whom the word "Czech" derives. The ninth century brought the state of Great Moravia, whose first ruler (Rastislav of Moravia) invited Byzantine ruler Michael III to send missionaries in an attempt to reduce the influence of East Francia on religious and political life in his country. These missionaries, Constantine and Methodius, helped to convert the Czechs from traditional Slavic paganism to Christianity and established a church system. They also brought the Glagolitic alphabet to the West Slavs, whose language was previously unwritten. This language, later known as Proto-Czech, was beginning to separate from its fellow West Slavic hatchlings Proto-Slovak, Proto-Polish and Proto-Sorbian. Among other features, Proto-Czech was marked by its ephemeral use of the voiced velar fricative consonant (//) and consistent stress on the first syllable.
Who was the hero who led the Slavs to their new home, according to legend?

ANS: Cech

Washington University supports four major student-run media outlets. The university's student newspaper, Student Life, is available for students. KWUR (90.3 FM) serves as the students' official radio station; the station also attracts an audience in the immediately surrounding community due to its eclectic and free-form musical programming. WUTV is the university's closed-circuit television channel. The university's main student-run political publication is the Washington University Political Review (nicknamed "WUPR"), a self-described "multipartisan" monthly magazine. Washington University undergraduates publish two literary and art journals, The Eliot Review and Spires Intercollegiate Arts and Literary Magazine. A variety of other publications also serve the university community, ranging from in-house academic journals to glossy alumni magazines to WUnderground, campus' student-run satirical newspaper.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How often are glossy alumni magazines sent out to former students?
Ah, so.. unanswerable

Question: Between 1945 and 1989, the share of ethnic Estonians in the population resident within the currently defined boundaries of Estonia dropped to 61%, caused primarily by the Soviet programme promoting mass immigration of urban industrial workers from Russia, Ukraine, and Belarus, as well as by wartime emigration and Joseph Stalin's mass deportations and executions.[citation needed] By 1989, minorities constituted more than one-third of the population, as the number of non-Estonians had grown almost fivefold.
Try to answer this question if possible: What year did minorities in Estonia make up more than a third of the country?
Answer: 1989

Input: Read this: The most accurate timekeeping devices are atomic clocks, which are accurate to seconds in many millions of years, and are used to calibrate other clocks and timekeeping instruments. Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second. One of the most common atoms used is caesium, most modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations. Since 1967, the International System of Measurements bases its unit of time, the second, on the properties of caesium atoms. SI defines the second as 9,192,631,770 cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the 133Cs atom.
Question: Which timekeeping devices are the least accurate?

Output:
unanswerable
