Which ethnic groups became a part of the United States by annexation?A.Mexicans and native HawaiiansB.Africans and EuropeansC.ChineseD.All of the above

To determine which ethnic groups became a part of the United States by annexation, let's analyze the options provided:

1. Mexicans and Native Hawaiians:

   • The annexation of Texas in 1845 involved significant numbers of Mexicans, as Texas was previously part of Mexico.
   • The annexation of Hawaii occurred in 1898, incorporating native Hawaiians into the United States.

2. Africans and Europeans:

   • While both Africans and Europeans contributed to the population of the U.S., their inclusion was largely through immigration rather than annexation.

3. Chinese:

   • Chinese immigrants primarily came to the U.S. during the Gold Rush and subsequent labor needs, and their presence was not due to annexation.

4. All of the above:

   • This option suggests that all mentioned groups became part of the U.S. through annexation, which is not entirely accurate.

Conclusion

The most accurate answer is A. Mexicans and Native Hawaiians, as they directly relate to the annexation events.
