Input: Read this: Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons.
Question: How many Jews immigrated to Germany before the fall of the Berlin Wall?

Output: unanswerable


QUES: After the incorporation of these states to the United States in the first half of the 19th century, the Spanish language was later reinforced in the country by the acquisition of Puerto Rico in 1898. Later waves of emigration from Mexico, Cuba, El Salvador and elsewhere in Hispanic America to the United States beginning in the second half of the 19th century to the present-day have strengthened the role of the Spanish language in the country. Today, Hispanics are one of the fastest growing demographics in the United States, thus increasing the use and importance of American Spanish in the United States.

What year did Puerto Rico become a state? 
What is the answer?

QUES: Because the electron mobility is higher than the hole mobility for all semiconductor materials, a given bipolar n–p–n transistor tends to be swifter than an equivalent p–n–p transistor. GaAs has the highest electron mobility of the three semiconductors. It is for this reason that GaAs is used in high-frequency applications. A relatively recent FET development, the high-electron-mobility transistor (HEMT), has a heterostructure (junction between different semiconductor materials) of aluminium gallium arsenide (AlGaAs)-gallium arsenide (GaAs) which has twice the electron mobility of a GaAs-metal barrier junction. Because of their high speed and low noise, HEMTs are used in satellite receivers working at frequencies around 12 GHz. HEMTs based on gallium nitride and aluminium gallium nitride (AlGaN/GaN HEMTs) provide a still higher electron mobility and are being developed for various applications.
What is the most common kind of semiconductor?

The level of Hellenistic achievement in astronomy and engineering is impressively shown by the Antikythera mechanism (150–100 BC). It is a 37-gear mechanical computer which computed the motions of the Sun and Moon, including lunar and solar eclipses predicted on the basis of astronomical periods believed to have been learned from the Babylonians. Devices of this sort are not found again until the 10th century, when a simpler eight-geared luni-solar calculator incorporated into an astrolabe was described by the Persian scholar, Al-Biruni.[not in citation given] Similarly complex devices were also developed by other Muslim engineers and astronomers during the Middle Ages.[not in citation given]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What range of years is the Antikythera mechanism thought to have been created?
Ah, so.. 150–100 BC


Question: Influences also came to her from the art world, most notably through the works of Mexican artist Frida Kahlo. The music video of the song "Bedtime Story" featured images inspired by the paintings of Kahlo and Remedios Varo. Madonna is also a collector of Tamara de Lempicka's Art Deco paintings and has included them in her music videos and tours. Her video for "Hollywood" (2003) was an homage to the work of photographer Guy Bourdin; Bourdin's son subsequently filed a lawsuit for unauthorised use of his father's work. Pop artist Andy Warhol's use of sadomasochistic imagery in his underground films were reflected in the music videos for "Erotica" and "Deeper and Deeper".
Try to answer this question if possible: Whose art influence Madonna?
Answer: Frida Kahlo


Question: Victoria married her first cousin, Prince Albert of Saxe-Coburg and Gotha, in 1840. Their nine children married into royal and noble families across the continent, tying them together and earning her the sobriquet "the grandmother of Europe". After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, republicanism temporarily gained strength, but in the latter half of her reign her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration.
Try to answer this question if possible: In the later half of her reign, what happened to her popularity?
Answer:
her popularity recovered
