Answer:
other great leaders throughout American history
Explanation:
When Kennedy says "those who came before us" he is referring to great American leaders inserted in the most diverse branches of industry, politics and science. Kennedy claims that it was these great leaders who allowed the United States to receive a wave of industrialization that promoted the country's advance and it was the duty of future leaders and Americans in general, not to allow these advances to go back, but to go even further.
A poem that consists of a three-part structure: a strophe, an antistrophe, and an epode - Pindaric ode. The strophe and the antistrophe have the same stanzaic and rhythmic pattern, with only the finale being different.
A ceremonious poem created by an ancient Greek poet who lived in the 5th century BC - also Pindaric ode. Pindar lived from 522 to 443 BC.
A rhymed ode that doesn't have a fixed number of lines per stanza - irregular ode. It doesn't have a prescribed rhyming pattern or stanzaic structure. It does rhyme, but not in a regular way.
A poem that doesn't follow any set structure and is open to experimentation - that is also irregular ode. As I already explained, it doesn't have to follow any rules.
Apart from these two types of odes, there is also the third, Horatian ode. It is divided into stanzas, but unlike Pindaric ode, they have the same length, meter, and rhyme.
I’m pretty sure the answer is B, but I would say you should also google parallelism examples online before you answer!
