Answer:
Correct answer is diary entries by President Carter
.
Explanation:
Third and fourth options are not correct as first of all textbook and encyclopedia are not a primary, but a secondary historical source.
On the other side, diary entries are the best primary source because are written sources from the perspective of someone who participated in certain events, in this case president Carter.
Second option is not correct option, but after the diary journal articles would be also important as are written in the period when certain events happened.
The correct answer is B.
<u>This is part of a radio speech delivered by President Roosevelt in December 1940</u> (this was the second year in WWII, and the US was still neutral in the conflict).
He aimed to convince the audience about the necessity of ensuring a safe defense strategy for Great Britain, so that they were able to avoid the German invasion and resist the many attacks they were suffering.
Apart from the ideological fight against nazism, Roosevelt highlighted how if GB fell, the last territory in the Atlantic, before reaching the US, would have been conquered. That would pose a direct threat on the US. <u>Therefore, he supported the idea that GB should remain free at any cost. </u>
