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.

original question: Which subatomic particle generation has the particles of [Charm quark]?
answer: second generation
answer type: Subatomic particle generation.
auxiliary information: The charm quark or c quark is the third most massive of all quarks, a type of elementary particle. Charm quarks are found in hadrons, which are subatomic particles made of quarks. Example of hadrons containing charm quarks include the J/ meson, D mesons, charmed Sigma baryons, and other charmed particles. It, along with the strange quark is part of the second generation of matter, and has an electric charge of + e and a bare mass of 1.29+0.05 0.11 GeV/c. Like all quarks, the charm quark is an elementary fermion with spin-, and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. The antiparticle of the charm quark is the charm antiquark, which differs from it only in that some of its properties have equal magnitude but opposite sign. The existence of a fourth quark had been speculated by a number of authors around 1964, but its prediction is usually credited to Sheldon Glashow, John Iliopoulos and Luciano Maiani in 1970. The first charmed particle to be discovered was the J/ meson.
The subatomic particle generation that has the particles of [Charm quark] is?
