Problem: Hard rock:

Emerging British acts included Free, who released their signature song "All Right Now" (1970), which has received extensive radio airplay in both the UK and US. After the breakup of the band in 1973, vocalist Paul Rodgers joined supergroup Bad Company, whose eponymous first album (1974) was an international hit. The mixture of hard rock and progressive rock, evident in the works of Deep Purple, was pursued more directly by bands like Uriah Heep and Argent. Scottish band Nazareth released their self-titled debut album in 1971, producing a blend of hard rock and pop that would culminate in their best selling, Hair of the Dog (1975), which contained the proto-power ballad "Love Hurts". Having enjoyed some national success in the early 1970s, Queen, after the release of Sheer Heart Attack (1974) and A Night at the Opera (1975), gained international recognition with a sound that used layered vocals and guitars and mixed hard rock with heavy metal, progressive rock, and even opera. The latter featured the single "Bohemian Rhapsody", which stayed at number one in the UK charts for nine weeks.

When did Free break up?

A: 1973

Problem: Punjab, Pakistan:

The structure of a mosque is simple and it expresses openness. Calligraphic inscriptions from the Quran decorate mosques and mausoleums in Punjab. The inscriptions on bricks and tiles of the mausoleum of Shah Rukn-e-Alam (1320 AD) at Multan are outstanding specimens of architectural calligraphy. The earliest existing building in South Asia with enamelled tile-work is the tomb of Shah Yusuf Gardezi (1150 AD) at Multan. A specimen of the sixteenth century tile-work at Lahore is the tomb of Sheikh Musa Ahangar, with its brilliant blue dome. The tile-work of Emperor Shah Jahan is of a richer and more elaborate nature. The pictured wall of Lahore Fort is the last line in the tile-work in the entire world.

When was Ahangar's tomb built?

A: sixteenth century

Problem: Translation:

The movement to translate English and European texts transformed the Arabic and Ottoman Turkish languages, and new words, simplified syntax, and directness came to be valued over the previous convolutions. Educated Arabs and Turks in the new professions and the modernized civil service expressed skepticism, writes Christopher de Bellaigue, "with a freedom that is rarely witnessed today.... No longer was legitimate knowledge defined by texts in the religious schools, interpreted for the most part with stultifying literalness. It had come to include virtually any intellectual production anywhere in the world." One of the neologisms that, in a way, came to characterize the infusion of new ideas via translation was "darwiniya", or "Darwinism".

What came to be hated over previous convolutions?
---
A: unanswerable

Problem: Printed circuit board:

Unpopulated boards are usually bare-board tested for "shorts" and "opens". A short is a connection between two points that should not be connected. An open is a missing connection between points that should be connected. For high-volume production a fixture or a rigid needle adapter is used to make contact with copper lands on the board. Building the adapter is a significant fixed cost and is only economical for high-volume or high-value production. For small or medium volume production flying probe testers are used where test probes are moved over the board by an XY drive to make contact with the copper lands. The CAM system instructs the electrical tester to apply a voltage to each contact point as required and to check that this voltage appears on the appropriate contact points and only on these.

A long is a connection between what?

A:
unanswerable
