Can you please check these other sentences I'm not sure of? Thank you.
1) After visiting the Roman findings (better ruins/remains) in Aquileia, we had a "free lunch". (we were free for lunch, we were free to have lunch where we wanted, our teachers gave us some free time for lunch)
2) We went sightseeing in Postumia (how do you call a sightseeing tour which is not guided?).
3) The only possible verb with sightseeing tour is "go on)" or are there other verbs (e.g. take).
4) We also visited a cemetery for the victims of te first World War.
Can you say "It was very beautiful an happy trip because I stayed with my friends"??
5)Have you written anything different you would like me to check (you)?
1) The correct term to use in that sentence would be "ruins" or "remains" of the Roman findings in Aquileia. As for the phrase "free lunch," it usually means that the lunch was provided without cost. If you mean that you had the freedom to choose where you wanted to have lunch, you could rephrase it as "we had the freedom to choose where to have lunch after visiting the Roman ruins in Aquileia."
2) A sightseeing tour that is not guided is often referred to as a "self-guided tour." This means that you explore the sights on your own without a guide.
3) While "go on" is a common verb used with sightseeing tours, you may also use verbs like "take," "have," or "enjoy" depending on the context. For example, you can say "We took a sightseeing tour of Postumia" or "We had a sightseeing tour of Postumia."
4) The sentence "We also visited a cemetery for the victims of the First World War" is correct and does not require any changes.
5) It would be more accurate to say, "It was a very beautiful and happy trip because I spent time with my friends." If you want to keep the word "stayed," you could rephrase it as "It was a very beautiful and happy trip because I stayed together with my friends."
