either ... or
neither ... nor
the less... the more

Neither railway staff nor rail infrastructure
was to blame for the fatal train crash this weekend
at a level crossing in Berkshire,
according to an initial investigation report released today

The Bush administration yesterday

saying it had picked up credible intelligence
of a possible terrorist attack
"that could either rival or exceed" September 11.
