Expert writing Tips
Best practice
Use "which are from" to provide additional, non-essential information about the source or origin of something. It's suitable when the information can be removed without changing the core meaning of the sentence.
Common error
Avoid using "that are from" instead of "which are from" when introducing non-restrictive clauses. "Which" is used for clauses that add extra information, while "that" is used for essential clauses that define the noun.
