Problem: Glacier:

The top 50 m (160 ft) of a glacier are rigid because they are under low pressure. This upper section is known as the fracture zone and moves mostly as a single unit over the plastically flowing lower section. When a glacier moves through irregular terrain, cracks called crevasses develop in the fracture zone. Crevasses form due to differences in glacier velocity. If two rigid sections of a glacier move at different speeds and directions, shear forces cause them to break apart, opening a crevasse. Crevasses are seldom more than 46 m (150 ft) deep but in some cases can be 300 m (1,000 ft) or even deeper. Beneath this point, the plasticity of the ice is too great for cracks to form. Intersecting crevasses can create isolated peaks in the ice, called seracs.

What are seracs?

A: isolated peaks in the ice

Problem: In October 1997, Nintendo released a redesigned model of the SNES (the SNS-101 model) in North America for US$99, which sometimes included the pack-in game Super Mario World 2: Yoshi's Island. Like the earlier redesign of the NES (the NES-101 model), the new model was slimmer and lighter than its predecessor, but it lacked S-Video and RGB output, and it was among the last major SNES-related releases in the region. A similarly redesigned Super Famicom Jr. was released in Japan at around the same time.
What was missing from the Super Famicom Jr.?

On 27 June, Rhee evacuated from Seoul with some of the government. On 28 June, at 2 am, the South Korean Army blew up the highway bridge across the Han River in an attempt to stop the North Korean army. The bridge was detonated while 4,000 refugees were crossing the bridge, and hundreds were killed. Destroying the bridge also trapped many South Korean military units north of the Han River. In spite of such desperate measures, Seoul fell that same day. A number of South Korean National Assemblymen remained in Seoul when it fell, and forty-eight subsequently pledged allegiance to the North.
What bridge were refugees attempting to cross when it was blown up by the South Korean Army?
A: Han River

Context and question: United States President Barack Obama and key advisers introduced a series of regulatory proposals in June 2009. The proposals address consumer protection, executive pay, bank financial cushions or capital requirements, expanded regulation of the shadow banking system and derivatives, and enhanced authority for the Federal Reserve to safely wind-down systemically important institutions, among others. In January 2010, Obama proposed additional regulations limiting the ability of banks to engage in proprietary trading. The proposals were dubbed "The Volcker Rule", in recognition of Paul Volcker, who has publicly argued for the proposed changes.
Who were proposed new regulations called "The Volcker Rule" named after?
Answer: Paul Volcker

Question: Other platings used are OSP (organic surface protectant), immersion silver (IAg), immersion tin, electroless nickel with immersion gold coating (ENIG), electroless nickel electroless palladium immersion gold (ENEPIG) and direct gold plating (over nickel). Edge connectors, placed along one edge of some boards, are often nickel plated then gold plated. Another coating consideration is rapid diffusion of coating metal into Tin solder. Tin forms intermetallics such as Cu5Sn6 and Ag3Cu that dissolve into the Tin liquidus or solidus(@50C), stripping surface coating or leaving voids.
Is there an answer to this question: What does OSP stand for?

Answer: organic surface protectant
