Problem: Glass:

In 2004, NIST researchers presented evidence that an isotropic non-crystalline metallic phase (dubbed "q-glass") could be grown from the melt. This phase is the first phase, or "primary phase," to form in the Al-Fe-Si system during rapid cooling. Interestingly, experimental evidence indicates that this phase forms by a first-order transition. Transmission electron microscopy (TEM) images show that the q-glass nucleates from the melt as discrete particles, which grow spherically with a uniform growth rate in all directions. The diffraction pattern shows it to be an isotropic glassy phase. Yet there is a nucleation barrier, which implies an interfacial discontinuity (or internal surface) between the glass and the melt.

What kind of microscope shows that q-glass grows as separate particles?

A: Transmission electron

Problem: Somalis:

The FIBA Africa Championship 1981 was hosted by Somalia from 1523 December 1981. The games were played in Mogadishu, and the Somali national team received the bronze prize. Abdi Bile won the 1500 m event at the World Championships in 1987, running the fastest final 800 m of any 1,500 meter race in history. He was a two-time Olympian (1984 and 1996) and dominated the event in the late 1980s. Hussein Ahmed Salah, a Somalia-born former long-distance runner from Djibouti, won a bronze medal in the marathon at the 1988 Summer Olympics. He also won silver medals in this event at the 1987 and 1991 World Championships, as well as the 1985 IAAF World Marathon Cup. Mo Farah is a double Olympic gold medal winner and world champion, and holds the European track record for 10,000 metres, the British road record for 10,000 metres, the British indoor record in the 3000 metres, the British track record for 5000 metres and the European indoor record for 5000 metres. Mohammed Ahmed (athlete) is a Canadian long-distance runner who represented Canada in the 10,000 meter races at the 2012 Summer Olympics and the 2013 World Championships in Athletics.

Who hosted the 1981 FIBA African Championship?

A: Somalia

Problem: ASCII:

The committee considered an eight-bit code, since eight bits (octets) would allow two four-bit patterns to efficiently encode two digits with binary-coded decimal. However, it would require all data transmission to send eight bits when seven could suffice. The committee voted to use a seven-bit code to minimize costs associated with data transmission. Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.:217, 2365 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.

Why did the committee decide on 7bit instead?
---
A: minimize costs associated with data transmission

Problem: FC Barcelona:

After the disappointment of the Gaspart era, the combination of a new young president, Joan Laporta, and a young new manager, former Dutch and Milan star Frank Rijkaard, saw the club bounce back. On the field, an influx of international players, including Ronaldinho, Deco, Henrik Larsson, Ludovic Giuly, Samuel Eto'o, and Rafael Marquez, combined with home grown Spanish players, such as Carles Puyol, Andres Iniesta, Xavi and Victor Valdes, led to the club's return to success. Barcelona won La Liga and the Supercopa de Espana in 200405, and Ronaldinho and Eto'o were voted first and third, respectively, in the FIFA World Player of the Year awards.

At this time, what type of players were added to Barcelona?

A:
international
