OA - An expansion of the American navy

Explanation:

By arguing that sea power—the strength of a nation’s navy—was the key to strong foreign policy, Alfred Thayer Mahan shaped American military planning and helped prompt a worldwide naval race in the late 19th and early 20th centuries. Mahan studied at Columbia for two years beginning in 1854—he was a member of the Philolexian Society, the campus literary club established in 1802—before decamping for Annapolis, from which he graduated in 1859. A longtime naval officer who cut his teeth on the Union side in the Civil War, Mahan eventually lectured on history and strategy at the Naval War College in Newport, R.I. It was there, inspired in part by a history of Rome, that he began developing his theories; in 1890 he turned his lecture notes into The Influence of Sea Power upon History, 1660-1783.

the topic i chose to write about was " why scuba diving is so popular". the topic is suitable for the audience because it is the easiest to develop and explain, it can be explained in a simpler more conversational manner, it does not require the use of too many technical words, and the final reason for selecting this topic is that it is the one most people can relate to, you might not know too much about scuba diving, but you could probably agree that it is very popular. the purpose of the writing about this topic is to convince more people about the benefits both for the body and the mind that   scuba diving can have on a person. it can you keep fit since it requires a lot of energy when swimming underwater; it also you relax because you forget about the world when you are underwater being mesmerized by the underwater world. i would write this paper in the summer, a perfect time to give scuba diving a try if a person has not done it yet.
