Identify the type of clause boldfaced in each sentence. World War II, which was the deadliest war in history, took the lives of
roughly 60 million soldiers and civilians. The United States remained neutral until the Japanese bombed Pearl Harbor on December 7, 1941. The most significant loss from the bombing occurred when a bomb hit the USS Arizona, detonating the ammunition magazines and causing the ship to explode. The following day, the United States declared war on Japan, which prompted Germany and Italy to declare war on the United States. Great Britain had already promised that it would immediately declare war on Japan if Japan launched an attack on the United States.
