Question: Passage: The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 15441549, a period which the writer Sir Walter Scott later christened the "Rough Wooing". In May 1544 an English army landed at Granton and captured Leith to land heavy artillery for an assault on Edinburgh Castle, but withdrew after burning the town and the Palace of Holyrood over three days. Three years later, following another English invasion and victory at Pinkie Cleugh in 1547, the English attempted to establish a "pale" within Scotland. Leith was of prime strategic importance because of its vital role as Edinburgh's port, handling its foreign trade and essential supplies. The English arrived in Leith on 11 September 1547 and camped on Leith Links. The military engineer Richard Lee scouted around the town on 12 September looking to see if it could be made defensible. On 14 September the English began digging a trench on the south-east side of Leith near the Firth of Forth. William Patten wrote that the work was done as much for exercise as for defence, since the army only stayed for five days.

Question: Passage: The island has been inhabited since at least 3rd century A.D. The 304-year-old Kingdom of Oahu was once ruled by the most ancient alii in all of the Hawaiian Islands. The first great king of Oahu was Mailikukahi, the lawmaker, who was followed by many generation of monarchs. Kualii was the first of the warlike kings and so were his sons. In 1773, the throne fell upon Kahahana, the son of Elani of Ewa. In 1783, Kahekili II, King of Maui, conquered Oahu and deposed the reigning family and then made his son, Kalanikupule, king of Oahu. Kamehameha the Great would conquer in the mountain Kalanikupule's force in the Battle of Nuuanu. Kamehameha founded the Kingdom of Hawaii with the conquest of Oahu in 1795. Hawaii would not be unified until the islands of Kauai and Niihau surrendered under King Kaumualii in 1810. Kamehameha III moved his capital from Lahaina, Maui to Honolulu, Oahu in 1845. Iolani Palace, built later by other members of the royal family, is still standing, and is the only royal palace on American soil.
