That or which 2

Do you have problems choosing between the relative pronouns that and which? Many people do. Here’s a tip: Use that to introduce adjective clauses that provide essential information about the noun they modify. Use which to introduce adjective clauses that merely provide additional, non-essential information. (A non-essential clause beginning with which is set off with a comma or commas.)
