Problem: Dell:

In the 1990s, Dell switched from using primarily ATX motherboards and PSU to using boards and power supplies with mechanically identical but differently wired connectors. This meant customers wishing to upgrade their hardware would have to replace parts with scarce Dell-compatible parts instead of commonly available parts. While motherboard power connections reverted to the industry standard in 2003, Dell continues to remain secretive about their motherboard pin-outs for peripherals (such as MMC readers and power on/off switches and LEDs).

What decade did Dell switch to SPUs and boards that had differently wired connectors?
---
A: unanswerable

Problem: Education:

Similarities in systems or even in ideas that schools share internationally have led to an increase in international student exchanges. The European Socrates-Erasmus Program facilitates exchanges across European universities. The Soros Foundation provides many opportunities for students from central Asia and eastern Europe. Programs such as the International Baccalaureate have contributed to the internationalization of education. The global campus online, led by American universities, allows free access to class materials and lecture files recorded during the actual classes.

What has come from similarities in systems?
---
A: increase in international student exchanges

Problem: Mandolin:

The Neapolitan style has an almond-shaped body resembling a bowl, constructed from curved strips of wood. It usually has a bent sound table, canted in two planes with the design to take the tension of the 8 metal strings arranged in four courses. A hardwood fingerboard sits on top of or is flush with the sound table. Very old instruments may use wooden tuning pegs, while newer instruments tend to use geared metal tuners. The bridge is a movable length of hardwood. A pickguard is glued below the sound hole under the strings. European roundbacks commonly use a 13-inch scale instead of the 13.876 common on archtop Mandolins.

What are the Neapolitan mandolin made of?
---
A: metal strings

Problem: Buckingham Palace:

On 15 September 1940, known as the Battle of Britain Day, an RAF pilot, Ray Holmes of No. 504 Squadron RAF rammed a German bomber he believed was going to bomb the Palace. Holmes had run out of ammunition and made the quick decision to ram it. Holmes bailed out. Both aircraft crashed. In fact the Dornier Do 17 bomber was empty. It had already been damaged, two of its crew had been killed and the remainder bailed out. Its pilot, Feldwebel Robert Zehbe, landed, only to die later of wounds suffered during the attack. During the Dornier's descent, it somehow unloaded its bombs, one of which hit the Palace. It then crashed into the forecourt of London Victoria station. The bomber's engine was later exhibited at the Imperial War Museum in London. The British pilot became a King's Messenger after the war, and died at the age of 90 in 2005.

What type of airplane was the German craft Holmes rammed into?
---
A:
Dornier Do 17 bomber
