input: Please answer the following: Extract the answer to the question from the following context. Question: What has the less preferable recovery rate? Context: For a variety of reasons, market participants did not accurately measure the risk inherent with financial innovation such as MBS and CDOs or understand its impact on the overall stability of the financial system. For example, the pricing model for CDOs clearly did not reflect the level of risk they introduced into the system. Banks estimated that $450bn of CDO were sold between "late 2005 to the middle of 2007"; among the $102bn of those that had been liquidated, JPMorgan estimated that the average recovery rate for "high quality" CDOs was approximately 32 cents on the dollar, while the recovery rate for mezzanine CDO was approximately five cents for every dollar.

output: mezzanine CDO
Please answer this: Extract the answer to the question from the following context. Question: If insulin/leptin function well, what result du they have? Context: Obesity can unfavourably alter hormonal and metabolic status via resistance to the hormone leptin, and a vicious cycle may occur in which insulin/leptin resistance and obesity aggravate one another. The vicious cycle is putatively fuelled by continuously high insulin/leptin stimulation and fat storage, as a result of high intake of strongly insulin/leptin stimulating foods and energy. Both insulin and leptin normally function as satiety signals to the hypothalamus in the brain; however, insulin/leptin resistance may reduce this signal and therefore allow continued overfeeding despite large body fat stores. In addition, reduced leptin signalling to the brain may reduce leptin's normal effect to maintain an appropriately high metabolic rate.

Answer: an appropriately high metabolic rate
Problem: Extract the answer to the question from the following context. Question: What was the exception to the standard number? Context: In 1925, 78.26 rpm was chosen as the standard because of the introduction of the electrically powered synchronous turntable motor. This motor ran at 3600 rpm, such that a 46:1 gear ratio would produce 78.26 rpm. In parts of the world that used 50 Hz current, the standard was 77.92 rpm (3,000 rpm with a 77:2 ratio), which was also the speed at which a strobe disc with 77 lines would "stand still" in 50 Hz light (92 lines for 60 Hz). After World War II these records were retroactively known as 78s, to distinguish them from other newer disc record formats. Earlier they were just called records, or when there was a need to distinguish them from cylinders, disc records.

A: parts of the world that used 50 Hz current, the standard was 77.92 rpm
