Problem: The last glacial period of the current ice age ended about 10,000 years ago. Ice melt caused world sea levels to rise about 35 metres (115 ft) in the early part of the Holocene. In addition, many areas above about 40 degrees north latitude had been depressed by the weight of the Pleistocene glaciers and rose as much as 180 metres (591 ft) over the late Pleistocene and Holocene, and are still rising today. The sea level rise and temporary land depression allowed temporary marine incursions into areas that are now far from the sea. Holocene marine fossils are known from Vermont, Quebec, Ontario and Michigan. Other than higher latitude temporary marine incursions associated with glacial depression, Holocene fossils are found primarily in lakebed, floodplain and cave deposits. Holocene marine deposits along low-latitude coastlines are rare because the rise in sea levels during the period exceeds any likely upthrusting of non-glacial origin. Post-glacial rebound in Scandinavia resulted in the emergence of coastal areas around the Baltic Sea, including much of Finland. The region continues to rise, still causing weak earthquakes across Northern Europe. The equivalent event in North America was the rebound of Hudson Bay, as it shrank from its larger, immediate post-glacial Tyrrell Sea phase, to near its present boundaries.
Glaciars from what period depressed the height of northern lands by 591 feet?
The answer is the following: Pleistocene

Problem: 1853: There were four main events. 1. In the north the Turks captured the border fort of Saint Nicholas in a surprise night attack (27/28 October). They then pushed about 20000 troops across the Cholok River border. Being outnumbered the Russians abandoned Poti and Redut Kale and drew back to Marani. Both sides remained immobile for the next seven months. 2. In the center the Turks moved north from Ardahan to within cannon-shot of Akhaltsike and awaited reinforcements (13 November). The Russians routed them. The claimed losses were 4000 Turks and 400 Russians. 3. In the south about 30000 Turks slowly moved east to the main Russian concentration at Gyumri or Alexandropol (November). They crossed the border and set up artillery south of town. Prince Orbeliani tried to drive them off and found himself trapped. The Turks failed to press their advantage, the remaining Russians rescued Orbeliani and the Turks retired west. Orbeliani lost about 1000 men out of 5000. The Russians now decided to advance, the Turks took up a strong position on the Kars road and attacked. They were defeated in the battle of Basgedikler, losing 6000 men, half their artillery and all their supply train. The Russians lost 1300, including Prince Orbeliani. This was Prince Ellico Orbeliani whose wife was later kidnaped by Shamyl at Tsinandali. 4. At sea the Turks sent a fleet east which was destroyed by Admiral Nakhimov at Sinope.
How many troops did the Turks send to Gyumri?
The answer is the following: 30000

Problem: The second major event of the early reign of Abd al-Malik was the construction of the Dome of the Rock in Jerusalem. Although the chronology remains somewhat uncertain, the building seems to have been completed in 692, which means that it was under construction during the conflict with Ibn al-Zubayr. This had led some historians, both medieval and modern, to suggest that the Dome of the Rock was built as a destination for pilgrimage to rival the Kaaba, which was under the control of Ibn al-Zubayr.
Where was the Dome of the Rock built?
The answer is the following: Jerusalem

Problem: On 11 April 1951, Commander-in-Chief Truman relieved the controversial General MacArthur, the Supreme Commander in Korea. There were several reasons for the dismissal. MacArthur had crossed the 38th parallel in the mistaken belief that the Chinese would not enter the war, leading to major allied losses. He believed that whether or not to use nuclear weapons should be his own decision, not the President's. MacArthur threatened to destroy China unless it surrendered. While MacArthur felt total victory was the only honorable outcome, Truman was more pessimistic about his chances once involved in a land war in Asia, and felt a truce and orderly withdrawal from Korea could be a valid solution. MacArthur was the subject of congressional hearings in May and June 1951, which determined that he had defied the orders of the President and thus had violated the U.S. Constitution. A popular criticism of MacArthur was that he never spent a night in Korea, and directed the war from the safety of Tokyo.
Who was relieved from his duties as Commander in Korea?
The answer is the following:
General MacArthur
