[EX Q]: By 1937, Japan controlled Manchuria and was ready to move deeper into China. The Marco Polo Bridge Incident on 7 July 1937 provoked full-scale war between China and Japan. The Nationalist and Communist Chinese suspended their civil war to form a nominal alliance against Japan, and the Soviet Union quickly lent support by providing large amount of materiel to Chinese troops. In August 1937, Generalissimo Chiang Kai-shek deployed his best army to fight about 300,000 Japanese troops in Shanghai, but, after three months of fighting, Shanghai fell. The Japanese continued to push the Chinese forces back, capturing the capital Nanking in December 1937 and committed which was known as Nanking Massacre. In March 1938, Nationalist forces won their first victory at Taierzhuang. but then the city of Xuzhou was taken by Japanese in May. In June 1938, Japan deployed about 350,000 troops to invade Wuhan and captured it in October. The Japanese achieved major military victories, but world opinionin particular in the United Statescondemned Japan, especially after the Panay Incident.

[EX Q]: It should be noted that many samurai forces that were active throughout this period were not deployed to Korea; most importantly, the daimyo Tokugawa Ieyasu carefully kept forces under his command out of the Korean campaigns, and other samurai commanders who were opposed to Hideyoshi's domination of Japan either mulled Hideyoshi's call to invade Korea or contributed a small token force. Most commanders who did opposed or otherwise resisted/resented Hideyoshi ended up as part of the so-called Eastern Army, while commanders loyal to Hideyoshi and his son (a notable exception to this trend was Kato Kiyomasa, who deployed with Tokugawa and the Eastern Army) were largely committed to the Western Army; the two opposing sides (so named for the relative geographical locations of their respective commanders' domains) would later clash, most notably at the Battle of Sekigahara, which was won by Tokugawa Ieyasu and the Eastern Forces, paving the way for the establishment of the Tokugawa Shogunate.
[EX A]: Which military leader avoided sending his soldiers to Korea?

[EX Q]: Birds have one of the most complex respiratory systems of all animal groups. Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs. When the bird exhales, the used air flows out of the lung and the stored fresh air from the posterior air sac is simultaneously forced into the lungs. Thus, a bird's lungs receive a constant supply of fresh air during both inhalation and exhalation. Sound production is achieved using the syrinx, a muscular chamber incorporating multiple tympanic membranes which diverges from the lower end of the trachea; the trachea being elongated in some species, increasing the volume of vocalizations and the perception of the bird's size.
[EX A]:
Upon inhalation, what percentage of fresh air bypasses the lungs and flows directly into a posterior air sac?
