\Ques{ 1}
Let $Z$ be a Zariski-closed set in $A^n$, the $n$-dimensional affine space over a
field $\F$.

zero divisors. \hfill (10~marks)
\item[(ii)]
Give an example, with justification, of an irreducible $Z$.

A generating set of an ideal $I\subset\F[x_1,\dots,x_n]$ is called \emph{universal Gr\"{o}bner basis}
if it is a Gr\"{o}bner basis of $I$ with respect to any term order.
Compute a universal Gr\"{o}bner basis of the ideal $(x-y^2,xy-x)\subset\C[x,y]$.
