Within the first two to four months of the bombings, the acute effects of the atomic bombings killed 90,000–146,000 people in Hiroshima and 39,000–80,000<span> in Nagasaki; roughly half of the deaths in each city occurred on the first day. hope this helps :D</span>
I think it is probably true, but not all at once when the bomb fell. So it depends on WHEN your teacher means.
If the question is about the few days around when the bomb was dropped, then the answer is False. I think there were about 150,000 that died in that time. Certainly more died later.
The legislative branch can declare war, among other things. Of course it is extremely rare and unlikely that the branch will do this without the consent of the President.
