Hi Guys
In AmE, there is a strong tendency to use '
that' in restrictive clauses.
However, it is not particularly uncommon to find '
which' also used with restrictive clauses (without a comma, of course).
And there are even some sentences in which we have little or no choice but to use '
which' with a restrictive clause.
