Expert writing Tips
Best practice
When using "which were delivered", ensure that the clause is nonrestrictive and adds extra information that isn't essential to the sentence's core meaning. Use commas to set off the "which" clause.
Common error
Avoid using "which" in restrictive clauses, which are essential to the meaning of the sentence. In such cases, use "that" instead. A helpful trick is to consider whether the information is necessary to identify the noun. If so, use "that"; if it's additional information, use "which."
