Read the excerpt from Dwight D. Eisenhower's Military-Industrial Complex speech and answer the question that follows.

A huge increase in newer elements of our defense; development of unrealistic programs to cure every ill in agriculture; a dramatic expansion in basic and applied research— (bolded text start) these and many other possibilities, each possibility promising in itself, (bolded text end) may be suggested as the only way to the road we wish to travel.

Which statement correctly identifies the rhetorical device in the bolded sentence and explains its effect on the text?

Chiasmus, because the reversal of the order of the sentence emphasizes the word "possibility"
Irony, because Eisenhower says the opposite of what he means to create a sense of humor in the text
Metonymy, because uses Eisenhower uses the word "agriculture" to replace farming
Zeugma, because the word "defense" applies to two others in different senses
