TASK DEFINITION: Given a paragraph, your job is to generate a question that can be answered from the passage. The answer to your question should be a single entity, person, time, etc. that can be extracted from the passage.
PROBLEM: Through combining the definition of electric current as the time rate of change of electric charge, a rule of vector multiplication called Lorentz's Law describes the force on a charge moving in a magnetic field. The connection between electricity and magnetism allows for the description of a unified electromagnetic force that acts on a charge. This force can be written as a sum of the electrostatic force (due to the electric field) and the magnetic force (due to the magnetic field). Fully stated, this is the law:

SOLUTION: What is  the time rate of change of electric charge?

PROBLEM: Many known complexity classes are suspected to be unequal, but this has not been proved. For instance P ⊆ NP ⊆ PP ⊆ PSPACE, but it is possible that P = PSPACE. If P is not equal to NP, then P is not equal to PSPACE either. Since there are many known complexity classes between P and PSPACE, such as RP, BPP, PP, BQP, MA, PH, etc., it is possible that all these complexity classes collapse to one class. Proving that any of these classes are unequal would be a major breakthrough in complexity theory.

SOLUTION: What is the unproven assumption generally ascribed to the value of complexity classes?

PROBLEM: Lindisfarne are a folk-rock group with a strong Tyneside connection. Their most famous song, 'Fog on the Tyne' (1971), was covered by Geordie ex-footballer Paul Gascoigne in 1990. Venom, reckoned by many to be the originators of black metal and extremely influential to the extreme metal scene as a whole, formed in Newcastle in 1979. Folk metal band Skyclad, often regarded as the first folk metal band, also formed in Newcastle after the break-up of Martin Walkyier thrash metal band, Sabbat. Andy Taylor, former lead guitarist of Duran Duran was born here in 1961. Brian Johnson was a member of local rock band Geordie before becoming the lead vocalist of AC/DC.

SOLUTION:
What genre of music is Lindisfarne classified as?
