Problem: Geological history of Earth:

The Carboniferous was a time of active mountain building, as the supercontinent Pangea came together. The southern continents remained tied together in the supercontinent Gondwana, which collided with North America-Europe (Laurussia) along the present line of eastern North America. This continental collision resulted in the Hercynian orogeny in Europe, and the Alleghenian orogeny in North America; it also extended the newly uplifted Appalachians southwestward as the Ouachita Mountains. In the same time frame, much of present eastern Eurasian plate welded itself to Europe along the line of the Ural mountains. There were two major oceans in the Carboniferous the Panthalassa and Paleo-Tethys. Other minor oceans were shrinking and eventually closed the Rheic Ocean (closed by the assembly of South and North America), the small, shallow Ural Ocean (which was closed by the collision of Baltica, and Siberia continents, creating the Ural Mountains) and Proto-Tethys Ocean.

What geologic events took place when Pangea combined during the Carboniferous?

A: mountain building

Problem: Madonna's seventh studio album, Ray of Light, (1998) reflected a change in her image. She collaborated with electronica producer William Orbit and wanted to create a sound that could blend dance music with pop and British rock. American music critic Ann Powers explained that what Madonna searched for with Orbit "was a kind of a lushness that she wanted for this record. Techno and rave was happening in the 90's and had a lot of different forms. There was very experimental, more hard stuff like Aphex Twin. There was party stuff like Fatboy Slim. That's not what Madonna wanted for this. She wanted something more like a singer-songwriter, really. And William Orbit provided her with that."
What year was "Ray of Light" released?

Answer: 1998

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The hourglass uses the flow of sand to measure the flow of time. They were used in navigation. Ferdinand Magellan used 18 glasses on each ship for his circumnavigation of the globe (1522). Incense sticks and candles were, and are, commonly used to measure time in temples and churches across the globe. Waterclocks, and later, mechanical clocks, were used to mark the events of the abbeys and monasteries of the Middle Ages. Richard of Wallingford (12921336), abbot of St. Alban's abbey, famously built a mechanical clock as an astronomical orrery about 1330. Great advances in accurate time-keeping were made by Galileo Galilei and especially Christiaan Huygens with the invention of pendulum driven clocks along with the invention of the minute hand by Jost Burgi.
How many inventions were made by Galileo?
A: unanswerable

Context and question: Hospital Maciel is one of the oldest hospitals in Uruguay and stands on the block bounded by the streets Maciel, 25 de Mayo, Guarani and Washington, with the main entrance at 25 de Mayo, 172. The land was originally donated in Spanish colonial times by philanthropist Francisco Antonio Maciel, who teamed up with Mateo Vidal to establish a hospital and charity. The first building was constructed between 1781 and 1788 and later expanded upon. The present building stems from the 1825 plans of Jose Toribio (son of Tomas Toribio) and later Bernardo Poncini (wing on the Guarani street, 1859), Eduardo Canstatt (corner of Guarani and 25 de Mayo) and Julian Masquelez (1889). The hospital has a chapel built in Greek style by Miguel Estevez in 1798.
Who originally donated the land for Hospital Macie?
Answer: Francisco Antonio Maciel

Question: However, the crisis did not exist in a void; it came after a long series of diplomatic clashes between the Great Powers over European and colonial issues in the decade prior to 1914 which had left tensions high. The diplomatic clashes can be traced to changes in the balance of power in Europe since 1870. An example is the Baghdad Railway which was planned to connect the Ottoman Empire cities of Konya and Baghdad with a line through modern-day Turkey, Syria and Iraq. The railway became a source of international disputes during the years immediately preceding World War I. Although it has been argued that they were resolved in 1914 before the war began, it has also been argued that the railroad was a cause of the First World War. Fundamentally the war was sparked by tensions over territory in the Balkans. Austria-Hungary competed with Serbia and Russia for territory and influence in the region and they pulled the rest of the great powers into the conflict through their various alliances and treaties. The Balkan Wars were two wars in South-eastern Europe in 19121913 in the course of which the Balkan League (Bulgaria, Montenegro, Greece, and Serbia) first captured Ottoman-held remaining part of Thessaly, Macedonia, Epirus, Albania and most of Thrace and then fell out over the division of the spoils, with incorporation of Romania this time.
Is there an answer to this question: What fundamental cause started the war in 1914?

Answer: tensions over territory in the Balkans.

QUES: Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened. Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own".[N 22] The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. Mabel and Bell mobilized the community to help victims in Halifax.

Which of their two homes did the Bells start spending more time as Bell aged?
What is the answer?
ANS:
Beinn Bhreagh
