The advantages public transport offers/the advantages of public transport

Hi all

- But how often do we see advertisements encouraging people to travel by public transport? It is essential to highlight all the advantages public transport offers.

My teacher suggested: But how often do we see advertisements encouraging people to travel by public transport? It is essential to highlight all the advantages of public transport.

Is the end of the first sentence wrong? If so, what does it make a bad sentence?

Thank you.
