4. I complained to the restaurant manager about the services. Another customer had already complained.(the second) I was the second person to complain to the restaurant manager about the services.Key Grammar RuleWhen you use ordinal numbers like the first, the second, the third, or the last, you follow it with a to-infinitive ($to + V_{inf}$). This is a more professional and concise way to rewrite sentences that originally use relative clauses (like "I was the second person who complained").Would you like me to help you with any other sentences from this exercise?
