Problem: Jehovah%27s Witnesses:

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 1977?

Problem: MP3:

Encoder / decoder overall delay is not defined, which means there is no official provision for gapless playback. However, some encoders such as LAME can attach additional metadata that will allow players that can handle it to deliver seamless playback.

Adding additional metadata allows players to handle gapless playback and deliver what?
---
A: seamless playback

Problem: Glass:

The term mainly refers to a mix of lithium and aluminosilicates that yields an array of materials with interesting thermomechanical properties. The most commercially important of these have the distinction of being impervious to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking. The negative thermal expansion coefficient (CTE) of the crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 C.

What proportion of crystalline ceramics yields a product with a CTE of around 1000?
---
A: unanswerable

Problem: 2008 Summer Olympics torch relay:

Internationally, the torch and its accompanying party traveled in a chartered Air China Airbus A330 (registered B-6075), painted in the red and yellow colors of the Olympic Games. Air China was chosen by the Beijing Committees of the Olympic Game as the designated Olympic torch carrier in March 2008 for its long-standing participation in the Olympic cause. The plane traveled a total of 137,000 km (85,000 mi) for a duration of 130 days through 21 countries and regions.

How many days did the plane travel?

A:
130 days
