Your sister must be a very gal. She knows where to get good information for certain, but I think Google might better suit you right now. Good luck and let us know how your report turns out.
That's a challenge to you. Write a great report and post it here for us and tell us what your grade is. Perhaps we can proof-read and edit it for you as well. (Don't let your teacher know that part :)
Very gal --> very SMART gal
i tried google i still got the same results
