Final answer:
Option III, "Junius, Socrates, Epaminondas, Cato the Younger, Sir Thomas More," is an example of allusion, referencing notable historical and literary figures. Since this option, along with option I, references well-known people, the correct answer is d. I and III.
Step-by-step explanation:
The student's question is asking to identify which excerpt from a given passage includes an example of allusion. An allusion is a reference in literature to a person, place, event, or another piece of literature, often without explicit identification. Option III, "Junius, Socrates, Epaminondas, Cato the Younger, Sir Thomas More," is an example of allusion, as it references historical and literary figures, thereby assuming the reader has knowledge of these individuals and their significance. This directly refers to personalities from history and literature, including philosophers, statesmen, and a saint, thereby linking the text with broader historical and cultural contexts. Therefore, option d. I and III would be correct if option I also contains an allusion, which it does as it references Caesar, a well-known historical figure. Option II, "I had the honor to have much conversation," does not contain a specific allusion.
