Final answer:
Set A is provided as a subset of the universal set U, but the question ends abruptly without specifying what needs to be found regarding set A. Clarification is needed to provide a complete answer.
Step-by-step explanation:
The question seems to have a typo or misprint since it ends with "Find (i) A" without giving further details about what to find regarding set A. Normally, in set theory, we might be asked to find the union, intersection or difference of sets, or even the complement of a set relative to the universal set. Nonetheless, given the sets provided (U, A, B, C), A simply represents one subset of the universal set U.
We could also potentially infer that the student might have intended to ask about the intersection or union of set A with sets B or C, but without further clarification, we are left to guess. An important follow-up would be to clarify exactly what the question is asking regarding set A.
