The correct answer is the last option.
The first hand grenades were used in World War I, in 1914. While hand-thrown weapons had been created hundreds of years earlier, they were reinvented during WWI according to the different requirements of trench warfare.
Answer:
There was no clear winner.
Explanation:
Although The Battle of Hampton Roads was not won by either side, the importance it had, was that it was the first battle of armored ships in history, and also included a development of notable war technologies: such as the rotating turret of the USS Monitor. The great battle between these battleships lasted for hours, and none was able to destroy the other; finally the USS Monitor made the ironclad Virginia retreat, unable to do real damage. This initiated a new form of maritime war, using ironclads, that soon would be much more advanced, like the ironclads or destroyers ships of the first world war.
