Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.

Question: original question: Which unit of charge is used in a measurement system that has the luminous flux units of [Lumen]? 
answer: coulomb
answer type: Unit of Charge.
auxiliary information: The lumen is the SI derived unit of luminous flux, a measure of the total "amount" of visible light emitted by a source. Luminous flux differs from power in that luminous flux measurements reflect the varying sensitivity of the human eye to different wavelengths of light, while radiant flux measurements indicate the total power of all electromagnetic waves emitted, independent of the eye's ability to perceive it. Lumens are related to lux in that one lux is one lumen per square meter. The lumen is defined in relation to the candela as 1 lm = 1 cd‚ãÖsr. A full sphere has a solid angle of 4œÄ steradians, so a light source that uniformly radiates one candela in all directions has a total luminous flux of 1 cd √ó 4œÄ sr = 4œÄ cd‚ãÖsr ‚âà 12.57 lumens.

Answer: Which unit of charge is used in the measurement system that includes the luminous flux units of [Lumen]?


Question: original question: Which filming location is featured in a concert film in [London]? 
answer: oakland, san francisco
answer type: Filming location.
auxiliary information: London /Ààl ånd…ôn/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core. The bulk of this conurbation forms Greater London, a region of England governed by the Mayor of London and the London Assembly. The conurbation also covers two English counties: the City of London and the county of Greater London. London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism, and transport all contributing to its prominence. It is one of the world's leading financial centres and has the fifth-or sixth-largest metropolitan area GDP in the world depending on measurement.

Answer: In a [London] concert film, which filming location is featured?


Question: original question: Which unit of energy is of the same measurement system as [Cubic metre per second]?
answer: joule, kilojoule
answer type: Unit of Energy.
auxiliary information: A cubic metre per second is a derived SI unit of volumetric flow rate equal to that of a stere or cube with sides of one metre in length exchanged or moving each second. It is popularly used for water flow, especially in rivers and streams, and fractions for HVAC values measuring air flow. The term cumec is also used, as shorthand for "Cubic metres per second", with the plural form cumecs also common in speech. It is commonly used between workers in the measurement of water flow through natural streams and civil works, but rarely used in writing. Data in units of cumec are used along the y-axis or vertical axis of a flow hydrograph, which describes the time variation of discharge of a river. A moderately sized river discharges in the order of 100 cumecs.

Answer:
What unit of energy is of the same measurement system as [Cubic metre per second]?
