Passage: Sporadic and isolated outbursts by Tibetans against the Chinese continued especially during the unrest between September 1987 until March 1989 in the Tibetan areas of the PRC. But it wasn't until 2008 that a large-scale and coordinated uprising erupted coinciding with international protests accompanying the Olympics torch relay that would end in Beijing where the 2008 Summer Olympics were held. What originally began as an annual observance of Tibetan Uprising Day turned into street protests by large numbers of monks from various monasteries for several days. Crowd control and arrests escalated the tensions eventually setting off a riot by thousands of Tibetans in the Ramoche section of Lhasa on March 14, 2008. When the police fled the scene, rioters looted and burned more than 1200 Chinese shops, offices, and residences and set fire to nearly 100 vehicles. In the end, an estimated 22 were dead and 325 injured, mostly Han. Total damage was estimated at $40 million USD. Eventually the paramilitary People's Armed Police were sent in and 50-100 Tibetan rioters were killed before things quieted down. Meanwhile, in the Gansu Province, a demonstration by 400 monks were met with force that ignited riots by more than 5000 Tibetans who again burned down the establishments of local Han and Hui people before security forces arrived.
Question: When were an estimated 325 Tibetan rioters injured?

Passage: Following a preliminary bombardment, the battle for Cebu City began on March 26, 1945, when the Allies launched Operation Victor II. Staging out of Leyte, where they had conducted rehearsal landings two days earlier, a large flotilla of cruisers and destroyers from the United States Seventh Fleet's Task Force 74 escorted the Cebu Attack Group to the island. Under the leadership of Major General William H. Arnold, the forces assigned to the operation consisted of the Americal Division's 132nd and 182nd Infantry Regiments, totaling about 5,000 men, were landed on Cebu island at Talisay Beach, 4 miles  southwest of Cebu City. The 182nd came ashore southwest of the city, while the 132nd landed at a wide gravel beach to the northeast opposite a palm grove. Meeting no Japanese opposition, the U.S. forces nevertheless suffered heavily from mines and booby traps as they crossed the beach.
Question: When were the rehearsal landings?

Passage: Manipur was a tributary to Burma in the 16th century  but had gone its own way since. It raided Upper Chindwin region in 1647 and 1692. However, in 1704, the raja of Manipur presented his daughter to Ava. Starting in the 1720s, Manipur under the leadership of Pamheiba  became a thorn to Upper Burma. In early 1724, the Manipuris raided Upper Burma. In response, an expedition force of 3,000 men marched to Manipur in November 1724. The army was ambushed in the swamps at Heirok, and retreated in haste. The Manipuris then returned ten years later. From 1735 to 1741, Manipuris raided the Upper Chindwin regions, increasingly deeper with each raid. Burmese defences were simply bypassed the Manipuris on their horseback. In December 1739, they reached as far as Sagaing, and looted and burned everything insight. The Burmese defences finally stopped them at Myedu in early 1741, with each side agreeing to an uneasy truce. But the Manipuris had annexed the Kabaw valley. The truce did not last. Another raid came all the way down to Ava in 1744. The last raid came in 1749. Upon arrival at Ava, the Manipuri chief found a large Burmese army, and presented his 12-year-old daughter instead, and left.
Question: What was the minimum year of the Manipur raiding of Upper Chindwin?
