Herbrand sentences

Show that the following sets of sentences are inconsistent by producing a set of inconsistent Herbrand sentences:

1. $\forall$x[x smokes  $\rightarrow$ $\neg$ x is wise],
   $\exists$x[x smokes $\wedge$ x is wise].
2. $\exists$x$\exists$y[x hates y],
   $\neg$$\exists$y$\exists$x[x hates y],
3. $\exists$x$\forall$y[x hates y],
   $\exists$y$\forall$x[$\neg$ x hates y],
