Problem: Energy:

There are strict limits to how efficiently heat can be converted into work in a cyclic process, e.g. in a heat engine, as described by Carnot's theorem and the second law of thermodynamics. However, some energy transformations can be quite efficient. The direction of transformations in energy (what kind of energy is transformed to what other kind) is often determined by entropy (equal energy spread among all available degrees of freedom) considerations. In practice all energy transformations are permitted on a small scale, but certain larger transformations are not permitted because it is statistically unlikely that energy or matter will randomly move into more concentrated forms or smaller spaces.

What is the direction of translations in energy?

Problem: When home prices declined in the latter half of 2007 and the secondary mortgage market collapsed, IndyMac was forced to hold $10.7 billion of loans it could not sell in the secondary market. Its reduced liquidity was further exacerbated in late June 2008 when account holders withdrew $1.55 billion or about 7.5% of IndyMac's deposits. This "run" on the thrift followed the public release of a letter from Senator Charles Schumer to the FDIC and OTS. The letter outlined the Senator's concerns with IndyMac. While the run was a contributing factor in the timing of IndyMac's demise, the underlying cause of the failure was the unsafe and unsound manner in which the thrift was operated.
What percent of IndyMac's deposits were withdrawn by account holders in late June 2008?

Answer: 7.5%

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The offices of elder and ministerial servant were restored to Witness congregations in 1972, with appointments made from headquarters (and later, also by branch committees). It was announced that, starting in September 2014, appointments would be made by traveling overseers. In a major organizational overhaul in 1976, the power of the Watch Tower Society president was diminished, with authority for doctrinal and organizational decisions passed to the Governing Body. Since Knorr's death in 1977, the position of president has been occupied by Frederick Franz (19771992) and Milton Henschel (19922000), both members of the Governing Body, and since 2000 by Don A. Adams, not a member of the Governing Body. In 1995, Jehovah's Witnesses abandoned the idea that Armageddon must occur during the lives of the generation that was alive in 1914 and in 2013 changed their teaching on the "generation".
Who was one of the members of the Governing Body in 1995?
A: unanswerable

In 2009 Tajikistan had 26 airports, 18 of which had paved runways, of which two had runways longer than 3,000 meters. The country's main airport is Dushanbe International Airport which as of April 2015, had regularly scheduled flights to major cities in Russia, Central Asia, as well as Delhi, Dubai, Frankfurt, Istanbul, Kabul, Tehran, and Urumqi amongst others. There are also international flights, mainly to Russia, from Khujand Airport in the northern part of the country as well as limited international services from Kulob Airport, and Qurghonteppa International Airport. Khorog Airport is a domestic airport and also the only airport in the sparsely populated eastern half of the country.
