1 is the answer to your question.
Answer:
Ethnicities.
Explanation:
An ethnic group or ethnicity is a certain social category of people based on the perception of its members that they have a common origin or experience. Members of an ethnic group believe that they share a common history and cultural traditions (such as language or beliefs) that separate them from other groups. An ethnic group can proclaim a nation claiming a territory, or constitute the majority population of a nation state, whose members or citizens similarly have a certain nationality.
Answer:
On 11 December 1941, four days after the Japanese attack on Pearl Harbor and the United States declaration of war against the Japanese Empire, Nazi Germany declared war against the United States, in response to what was claimed to be a series of provocations by the United States government when the US was still officially neutral during World War II. The decision to declare war was made by Adolf Hitler, apparently offhand, almost without consultation. Later that day, the United States declared war on Germany.
