Answer:
A) Mostly positive, but with word choices that warn against hostile activities
Step-by-step explanation:
This excerpt is from John F. Kennedy's Inaugural Address, January 20, 1961. In the previous decade the USA's relations with Latin America have not been at good terms. So, he is referring to the Latin American countries by calling them sister republics south of our border.
The speech uses many positive words such as, "sister republics", "good words", "good deeds", "alliance for progress", "peaceful revolution of hope", "join them". The speech also warns other powers and southern republics of any hostile activities by using phrases and words such as, "cannot become the prey of hostile powers", "let all our neighbors know", "let every other power know", "intends to remain the master of its own house."
