I think 1 should be "In this day and age, flying around the world IS no big deal
2 should be "However, could a person do in the 20th century what jules vernes character DID in 1872. 3 should be In 1989 Michael Palin and a BBC TV crew accepted the challenge and ATTEMPTED to go by land and sea around the globe in 80 days. 4 should be Vernes phileas fogg and his servant passepartout LEFT on their journey from charing cross station. 5 should be palin and his crew started in London on a train THAT LEAVES from victoria station. 6 should be in saudi arabia, bureaucrats had restricted train travel, so palin DROVE through the desert, but his TV crew flew. 7 should be While they WERE CROSSING the persian gulf in a small ship called a dhow, palin became seasick. 8 should be on their trip across the united states by train, they STOPPED in colorado and went for a ride in dogsled. 9 should be they RETURNED to London at the end of 80 days but missed their station because of a bomb scare. 10 should be in the 21st century, probably some traveler WOULD HAVE TRIED the trip again, keeping the spirit of adventure alive.
It took me a long time to read over all of it and type it all out so there might be an error but that should be mostly correct :) Hope this helps!!
