TASK 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.
PROBLEM: original question: Which animal breed is the breed of [Guinea pig]?
answer: himalayan guinea pig, teddy guinea pig, skinny pig...
answer type: Animal breed.
auxiliary information: The guinea pig, also called the cavy, is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not in the pig family, nor are they from Guinea. They originated in the Andes, and earlier studies based on biochemistry and hybridization suggested they are domesticated descendants of a closely related species of cavy such as Cavia aperea, C. fulgida, or C. tschudii and, therefore, do not exist naturally in the wild. Recent studies applying molecular markers, in addition to studying the skull and skeletal morphology of current and mummified animals, revealed that the ancestor is most likely Cavia tschudii. The guinea pig plays an important role in the folk culture of many Indigenous South American groups, especially as a food source, but also in folk medicine and in community religious ceremonies. Since the 1960s, efforts have been made to increase consumption of the animal outside South America. In Western societies, the guinea pig has enjoyed widespread popularity as a household pet since its introduction by European traders in the 16th century.

SOLUTION: A [Guinea pig] is included in what type of animal breed?

PROBLEM: original question: what Patent has an Associated Invention that is associated with the patent [Multidimensional digital waveguide signal synthesis system and method (tetrahedral extension)]?
answer: multidimensional digital waveguide signal synthesis system and method
answer type: Patent.
auxiliary information: This variation on the Digital Waveguide Mesh design comprises bidirectional unit delays and 4-way no-multiply junction computations to model wave propagation in 3D space or homogenous solids.  It is based on an equivalence under certain conditions of modeling of transmission line scattering as digital waveguides and partial finite difference schemes for 3d wave propagation.

SOLUTION: Which patent is associated with [Multidimensional digital waveguide signal synthesis system and method (tetrahedral extension)]?

PROBLEM: original question: what Piston configuration is the Piston engine that is the Variation of [Rolls-Royce Merlin I]?
answer: v12 engine
answer type: Piston configuration.
auxiliary information: Rolls-Royce Merlin I engine was the first variant of the Rolls-Royce Merlin engines produced.

SOLUTION:
When it comes to the Variation of [Rolls-Royce Merlin I] what Piston configuration is the Piston engine?
