Problem: The uneasy alliance of Carranza, Obregón, Villa, and Zapata eventually led the rebels to victory. The fight against Huerta formally ended on August 15, 1914, when Álvaro Obregón signed a number of treaties in Teoloyucan in which the last of Huerta's forces surrendered to him and recognized the constitutional government. On August 20, 1914, Carranza made a triumphal entry into Mexico City. Carranza (supported by Obregón) was now the strongest candidate to fill the power vacuum and set himself up as head of the new government. This government successfully printed money, passed laws, etc.

Problem: While Japan had a large number of submarines, they did not make a significant impact on the war. In 1942, the Japanese fleet subs performed well, knocking out or damaging many Allied warships. However, Imperial Japanese Navy (and pre-war U.S.) doctrine stipulated that only fleet battles, not guerre de course (commerce raiding) could win naval campaigns. So, while the US had an unusually long supply line between its west coast and frontline areas, leaving it vulnerable to submarine attack, Japan used its submarines primarily for long-range reconnaissance and only occasionally attacked U.S. supply lines. The Japanese submarine offensive against Australia in 1942 and 1943 also achieved little.
What was the primary use of Japanese submarines?
The answer is the following: long-range reconnaissance

Problem: Starting in 2006, Apple's industrial design shifted to favor aluminum, which was used in the construction of the first MacBook Pro. Glass was added in 2008 with the introduction of the unibody MacBook Pro. These materials are billed as environmentally friendly. The iMac, MacBook Pro, MacBook Air, and Mac Mini lines currently all use aluminum enclosures, and are now made of a single unibody. Chief designer Jonathan Ive continues to guide products towards a minimalist and simple feel, including eliminating of replaceable batteries in notebooks. Multi-touch gestures from the iPhone's interface have been applied to the Mac line in the form of touch pads on notebooks and the Magic Mouse and Magic Trackpad for desktops.
