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 fuel when combined with [Hydrogen peroxide] provides a maximum thrust of <2> in a bipropellant rocket engine?
answer: pentaborane, beryllium-hydrazine mix, kerosene
answer type: Rocket engine fuel.
auxiliary information: Hydrogen peroxide is a chemical compound with the formula H 2O 2. In its pure form it is a colourless liquid, slightly more viscous than water; however, for safety reasons it is normally used as an aqueous solution. Hydrogen peroxide is the simplest peroxide and finds use as a strong oxidizer, bleaching agent and disinfectant. Concentrated hydrogen peroxide, or 'high-test peroxide,' is a reactive oxygen species and has been used as a propellant in rocketry. Hydrogen peroxide is often described as being ‚Äúwater but with one more oxygen atom‚Äù, a description which can give the incorrect impression that there is a great deal of similarity between the two compounds. Pure hydrogen peroxide will explode if heated to boiling, will cause serious contact burns to the skin and can set materials alight on contact. For these reasons it is usually handled as a dilute solution. Its chemistry is dominated by the nature of its unstable peroxide bond.

When combined with [Hydrogen peroxide], what fuel provides a maximum thrust of <2> in a bipropellant rocket engine?
