President Roosevelt called December 7, 1941, “a date which will live in infamy.” Which of these definitions is the best meaning of the word “infamy”?

the literal definition is a well known for some bad quality or deed. Just think of a bad person in history. We would call that person Infamous because of his actions. This goes the same for Infamy. Hes saying that this horrible attack will live in Infamy(which means well known terrible thing) we will remember forever. Hope this helps

idk

option d is correct. corroborated sources of historical evidence   is necessary to validate a claim about an event in history.

historians tend to use written sources, but audio and visual materials as well as artifacts are important objects that supply information to modern historians.

historical sources are usually divided into two categories: primary and secondary sources. depending on the historian's intent, some sources shift their designation. determining what type of sources toimplement, and the level of credibility and reliability of those sources, is a significant step in critical thinking for the historian.
