Problem: The current "Precentor" (Head of Music) is Tim Johnson, and the School boasts eight organs and an entire building for music (performance spaces include the School Hall, the Farrer Theatre and two halls dedicated to music, the Parry Hall and the Concert Hall). Many instruments are taught, including obscure ones such as the didgeridoo. The School participates in many national competitions; many pupils are part of the National Youth Orchestra, and the School gives scholarships for dedicated and talented musicians. A former Precentor of the college, Ralph Allwood set up and organised Eton Choral Courses, which run at the School every summer.
Who now organizes the Eton Choral Courses?

Problem: Like other historical languages, Old English has been used by scholars and enthusiasts of later periods to create texts either imitating Anglo-Saxon literature or deliberately transferring it to a different cultural context. Examples include Alistair Campbell and J. R. R. Tolkien. A number of websites devoted to Neo-Paganism and Historical re-enactment offer reference material and forums promoting the active use of Old English. By far the most ambitious project[peacock term] is the Old English Wikipedia, but most of the Neo-Old English texts published online bear little resemblance to the historical model and are riddled with very basic grammatical mistakes.
What is one of the few languages imitated by scholars?

Problem: A common application of a torque motor would be the supply- and take-up reel motors in a tape drive. In this application, driven from a low voltage, the characteristics of these motors allow a relatively constant light tension to be applied to the tape whether or not the capstan is feeding tape past the tape heads. Driven from a higher voltage, (and so delivering a higher torque), the torque motors can also achieve fast-forward and rewind operation without requiring any additional mechanics such as gears or clutches. In the computer gaming world, torque motors are used in force feedback steering wheels.
In a tape drive, what is needed if a torque motor is used?
