Expert writing Tips
Best practice
Use "which discussed" to clearly indicate the subject matter of a prior statement or text, ensuring a smooth flow of information and avoiding ambiguity. Example: "The report, which discussed the latest findings, was insightful."
Common error
Avoid using "that" when "which" is appropriate. "That" is used for restrictive clauses (essential to the sentence's meaning), while "which" is used for non-restrictive clauses (adding extra information). Example: Wrong: "The book that discussed climate change is informative." Correct: "The book, which discussed climate change, is informative."
