“One disadvantage is that it can be crowded. During rush hours, buses and trains are packed with commuters, which leads to less space. Whenever a bus or train brakes suddenly, it can cause passengers to bump into one another.”

Can you show me a proper way to write the paragraph above by using two examples because that is what my instructor told me to do, can you please do it for me so I can hand it in, also explain more about about the disadvantage of buses and trains during rush hours, make sure to use proper punctuation and spelling?
