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.

Question: original question: Which composition has the subjects of [Mother]?
answer: mother
answer type: Composition.
auxiliary information: Mothers are women who inhabit or perform the role of bearing some relation to their children, who may or may not be their biological offspring. Thus, dependent on the context, women can be considered mothers by virtue of having given birth, by raising their child, supplying their ovum for fertilization, or some combination thereof. Such conditions provide a way of delineating the concept of motherhood, or the state of being a mother. Women who meet the third and first categories usually fall under the terms 'birth mother' or 'biological mother', regardless of whether the individual in question goes on to parent their child. Accordingly, a woman who meets only the second condition may be considered an adoptive mother, and those who meet only the third a surrogacy mother. The above concepts defining the role of mother are neither exhaustive nor universal, as any definition of 'mother' may differ based on how social, cultural, and religious roles are defined. The parallel conditions and terms for males: those who are fathers do not, by definition, take up the role of fatherhood. It should also be noted that mother and fatherhood are not limited to those who are or have parented.

Answer:
[Mother] subjects have what composition?
