(2) For the following assertions, determine whether the each statement is true or false. If you claim that it is true, provide a short sketch proof why; if you claim that it is false, provide a counterexample. (a) The union of two subrings is a subring. (b) (Z₁, +p: .p), where p is prime, has no proper subfield. (c) Q is the only subfield of R.
