Best practice
Use "which involve" to introduce nonrestrictive clauses that provide additional information about the preceding noun or noun phrase. These clauses are set off by commas.
Common error
Avoid using "that involve" when you need a nonrestrictive clause (one that adds extra, non-essential information). Use "which involve" and set the clause off with commas. "That" is for restrictive clauses that are essential to the sentence's meaning.
