Hello teachers.Im student at university.I need help please about this pharagraph.Colourful words are mine wrong answers ,and which in parenthesiss are right answers.
Im not be able to understand why mine are wrong where is the difference.Could you explain please.
The other day I drove my car to the downtown campus of the collage.I usually have a certain amount of trouble finding a parking place,however(but) this time really took the cake.There were simply no parking places therefore

I had to park in the downtown mall,which is about a mile from the campus.When I finished classs,I walked back to the mall.But(however) I couldnt remember where I'd parked my car.Believe it or not,it took me forty-five minutes to find it,and I was about ready to panic when I finally did.That was the last straw.I have decided that Im going to send my car to a new home in the suburbs.
I used to think that a car was the most wonderful thing in the world.I loved the freedom of being able to come and go to my part time job or to the collage whenever I wanted. A year ago I was in a carpool with four other people,however(but) I hated having to wait around on account(because) of my carpool members werent ready to leave,so I started driving alone.
Although(however)I have changed my mind since then.Now its clear to me that there are just too many disadventages to having a car in town.For one thing,sitting stalled in your car in a traffic jam is stressful,besides(and)its a phenomenal waste of time.In addition,it would cost me $200 a month to park my car in the city,also(and)there is always the chance it will be vandalized.
Nonetheless(therefore)I have decided to leave it at my cousin Brent's house in the suburbs.Or(otherwiseI will end up going broke paying for parking or memory improvement.My car will have a good home also(and)I will use it just for longer trips.When Im in the cityalthough(though),I will take the bus or the trolley,otherwise(or) I will walk.Who knows?They say that you can meet some interesting people on the bus.Maybe I'll find the love of my life.My only problem will be remembering which bus to take.
