During WWII, in 1945, the United States dropped atomic bombs on the two Japanese cities of Hiroshima and what other city?

The story behind the answer

Nagasaki is correct because it was the second city struck with an atomic bomb in WWII: after “Little Boy” hit Hiroshima on August 6, 1945, the U.S. dropped “Fat Man” on Nagasaki on August 9. The bombings, unlike the earlier firebombing of Tokyo, used nuclear weapons and pushed Japan to announce its surrender within days.
