Question: In 2003, a congestion charge was introduced to reduce traffic volumes in the city centre. With a few exceptions, motorists are required to pay £10 per day to drive within a defined zone encompassing much of central London. Motorists who are residents of the defined zone can buy a greatly reduced season pass. London government initially expected the Congestion Charge Zone to increase daily peak period Underground and bus users by 20,000 people, reduce road traffic by 10 to 15 per cent, increase traffic speeds by 10 to 15 per cent, and reduce queues by 20 to 30 per cent.

Question: Like any plucked instrument, mandolin notes decay to silence rather than sound out continuously as with a bowed note on a violin, and mandolin notes decay faster than larger stringed instruments like the guitar. This encourages the use of tremolo (rapid picking of one or more pairs of strings) to create sustained notes or chords. The mandolin's paired strings facilitate this technique: the plectrum (pick) strikes each of a pair of strings alternately, providing a more full and continuous sound than a single string would.
Is there an answer to this question:  What is a slectrum?

Answer:
unanswerable
