[EX Q]: On 25 May 1963, the pope suffered another haemorrhage and required several blood transfusions, but the cancer had perforated the stomach wall and peritonitis soon set in. The doctors conferred in a decision regarding this matter and John XXIII's aide Loris F. Capovilla broke the news to him saying that the cancer had done its work and nothing could be done for him. Around this time, his remaining siblings arrived to be with him. By 31 May, it had become clear that the cancer had overcome the resistance of John XXIII – it had left him confined to his bed.
[EX A]: What did the pope suffer on 25 May 1963?

[EX Q]: The first real progress toward a modern understanding of nervous function, though, came from the investigations of Luigi Galvani, who discovered that a shock of static electricity applied to an exposed nerve of a dead frog could cause its leg to contract. Since that time, each major advance in understanding has followed more or less directly from the development of a new technique of investigation. Until the early years of the 20th century, the most important advances were derived from new methods for staining cells. Particularly critical was the invention of the Golgi stain, which (when correctly used) stains only a small fraction of neurons, but stains them in their entirety, including cell body, dendrites, and axon. Without such a stain, brain tissue under a microscope appears as an impenetrable tangle of protoplasmic fibers, in which it is impossible to determine any structure. In the hands of Camillo Golgi, and especially of the Spanish neuroanatomist Santiago Ramón y Cajal, the new stain revealed hundreds of distinct types of neurons, each with its own unique dendritic structure and pattern of connectivity.
[EX A]: Who found out that a shock of electricity to an exposed nerve of a dead frog caused contractions?

[EX Q]: Against the rested and re-armed Pusan Perimeter defenders and their reinforcements, the KPA were undermanned and poorly supplied; unlike the UN Command, they lacked naval and air support. To relieve the Pusan Perimeter, General MacArthur recommended an amphibious landing at Inchon (now known as Incheon), near Seoul and well over 100 miles (160 km) behind the KPA lines. On 6 July, he ordered Major General Hobart R. Gay, Commander, 1st Cavalry Division, to plan the division's amphibious landing at Incheon; on 12–14 July, the 1st Cavalry Division embarked from Yokohama, Japan to reinforce the 24th Infantry Division inside the Pusan Perimeter.

Why did General MacArthur suggest an amphibious landing at Inchon?
