Best practice
When using "which contained", verify that the sentence remains grammatically correct and clear if the "which contained" clause is removed. If removing the clause alters the core meaning, consider using "that contained" instead.
Common error
Avoid using "that contained" when "which contained" is more appropriate. "Which" introduces non-restrictive clauses that add extra information, whereas "that" introduces essential clauses. Using the wrong one can confuse readers.
