Expert writing Tips
Best practice
When using "which called for", ensure that the clause preceding "which" clearly identifies the subject or action that necessitates the subsequent requirement.
Common error
Avoid using "that" in place of "which" when introducing nonrestrictive clauses (clauses that add extra information but are not essential to the sentence's meaning). "Which", preceded by a comma, is correct for nonrestrictive clauses.

What are some alternatives to "which called for"?

Is it more appropriate to use "that called for" instead of "which called for"?

How does "which called for" differ from "that called for"?
