Which of the following is NOT a work of Terence?

The correct answer, identifying which work is not by Terence, is "De Rerum Natura." This is a poem by the Roman philosopher and poet Lucretius, written in the 1st century BCE. Lucretius' work is a significant philosophical text that explores Epicurean ideas such as the nature of the universe, the workings of the material world, and the idea of pleasure as the ultimate aim of human life.

In contrast, the other titles listed—"Andria," "Phormio," and "Eunuchus"—are indeed comedic plays authored by Terence, a notable figure in Roman literature known for his contributions to comic theater. "Andria," his first play, deals with themes of love and mistaken identity; "Phormio" features clever plots and character interactions commonly found in Terence's work; and "Eunuchus" focuses on themes of love and deception, showcasing Terence's style that blends humor with moral lessons.

Understanding these distinctions helps clarify the literary contributions of these authors and their respective genres in classical literature.
