Problem: Adult contemporary music:

This format often includes dance-pop (such as upbeat songs by Madonna, Cher, Gloria Estefan and Kylie Minogue), power pops (mainly by boybands such as Backstreet Boys and Westlife), and adult-oriented soft rock music that are ballad-driven (typically by Aerosmith[citation needed], The Eagles, Sting, Toto and The Moody Blues). Generally, Hot AC radio stations target their music output towards the 18-54 age group and a demographic audience of both men and women.

What genre of music is played by The Eagles?
---
A: soft rock


Problem: Incandescent light bulb:

During ordinary operation, the tungsten of the filament evaporates; hotter, more-efficient filaments evaporate faster. Because of this, the lifetime of a filament lamp is a trade-off between efficiency and longevity. The trade-off is typically set to provide a lifetime of several hundred to 2,000 hours for lamps used for general illumination. Theatrical, photographic, and projection lamps may have a useful life of only a few hours, trading life expectancy for high output in a compact form. Long-life general service lamps have lower efficiency but are used where the cost of changing the lamp is high compared to the value of energy used.

What determines how fast a tungsten filament evaporates?
---
A: hotter, more-efficient filaments evaporate faster


Problem: Somerset:

The county has a long tradition of supplying freestone and building stone. Quarries at Doulting supplied freestone used in the construction of Wells Cathedral. Bath stone is also widely used. Ralph Allen promoted its use in the early 18th century, as did Hans Price in the 19th century, but it was used long before then. It was mined underground at Combe Down and Bathampton Down Mines, and as a result of cutting the Box Tunnel, at locations in Wiltshire such as Box. Bath stone is still used on a reduced scale today, but more often as a cladding rather than a structural material. Further south, Hamstone is the colloquial name given to stone from Ham Hill, which is also widely used in the construction industry. Blue Lias has been used locally as a building stone and as a raw material for lime mortar and Portland cement. Until the 1960s, Puriton had Blue Lias stone quarries, as did several other Polden villages. Its quarries also supplied a cement factory at Dunball, adjacent to the King's Sedgemoor Drain. Its derelict, early 20th century remains, was removed when the M5 motorway was constructed in the mid-1970s. Since the 1920s, the county has supplied aggregates. Foster Yeoman is Europe's large supplier of limestone aggregates, with quarries at Merehead Quarry. It has a dedicated railway operation, Mendip Rail, which is used to transport aggregates by rail from a group of Mendip quarries.

In what decade was Mendip Rail built?
---
A: unanswerable


Problem: Gamal Abdel Nasser:

The crowd roared in approval and Arab audiences were electrified. The assassination attempt backfired, quickly playing into Nasser's hands. Upon returning to Cairo, he ordered one of the largest political crackdowns in the modern history of Egypt, with the arrests of thousands of dissenters, mostly members of the Brotherhood, but also communists, and the dismissal of 140 officers loyal to Naguib. Eight Brotherhood leaders were sentenced to death, although the sentence of its chief ideologue, Sayyid Qutb, was commuted to a 15-year imprisonment. Naguib was removed from the presidency and put under house arrest, but was never tried or sentenced, and no one in the army rose to defend him. With his rivals neutralized, Nasser became the undisputed leader of Egypt.

To what group did many of the arrested dissenters belong?
---
A:
Brotherhood
