I'm getting really confused trying to identify how many clauses are in this sentence and was just wondering if anyone could please advise. It's the 'also' that is throwing me off as surely I cannot have two separate clauses if this is used? Is it just one clause?
- "Two of the key characteristics that make nylon so useful also make it a significant environmental threat."
Thank you for any help with this. (PS. Please go easy on me, I'm new to this!)
