[EX Q]: Passage: The innovative production techniques devised by post-punk producers such as Martin Hannett and Dennis Bovell during this period would become an important element of the emerging music, with studio experimentation taking a central role. A variety of groups that predated punk, such as Cabaret Voltaire and Throbbing Gristle, experimented with crude production techniques and electronic instruments in tandem with performance art methods and influence from transgressive literature, ultimately helping to pioneer industrial music. Throbbing Gristle's independent label Industrial Records would become a hub for this scene and provide it with its namesake.
[EX A]: Who avoided post-punk production?

[EX Q]: Passage: All equipment must be suitable for a mixed-gender force. Combat helmets, rucksacks, combat boots, and flak jackets are designed to ensure women have the same level of protection and comfort as their male colleagues. The women's uniform is similar in design to the men's uniform, but conforms to the female figure, and is functional and practical. Women are also provided with an annual financial entitlement for the purchase of brassiere undergarments.

[EX Q]: Passage: The name Shell is linked to The "Shell" Transport and Trading Company. In 1833, the founder's father, Marcus Samuel, founded an import business to sell seashells to London collectors. When collecting seashell specimens in the Caspian Sea area in 1892, the younger Samuel realised there was potential in exporting lamp oil from the region and commissioned the world's first purpose-built oil tanker, the Murex (Latin for a type of snail shell), to enter this market; by 1907 the company had a fleet. Although for several decades the company had a refinery at Shell Haven on the Thames, there is no evidence of this having provided the name.
[EX A]:
Where was the Murex built?
