Definition: 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.
Input: original question: What is the cell type of a battery whose size is [AA battery]?
answer: alkaline battery
answer type: Battery cell type.
auxiliary information: An AA battery‚Äîalso called a double A or Mignon battery‚Äîis a standard size single cell cylindrical dry battery. The IEC system calls it size R6, and ANSI calls it size 15. AA batteries are common in portable electronic devices. An AA battery is composed of a single electrochemical cell that may be either a primary battery or a rechargeable battery. The exact terminal voltage and capacity of an AA size battery depends on cell chemistry. AA batteries account for over 50% of general battery sales. Introduced in 1907, the AA battery size was standardized by the American National Standards Institute in 1947, but it had been used in flashlights and electrical novelties for some time before formal standardization. ANSI and IEC Battery nomenclature gives several designations for cells in this size, depending on cell features and chemistry.
