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.

auxiliary information: Ferdinand Lemaire was a French librettist and poet, best known for writing the libretto of Camille Saint-Saens's opera Samson et Dalila. Lemaire was a creole, originally from Martinique, and had married a cousin of Saint-Saens's wife. Saint-Saens had previously set two of his poems, "Souvenance" and "Tristesse", for voice and piano. Approached by the composer to write an oratorio on the story of Samson and Delilah, Lemaire agreed, but only if the work was to be an opera.
