The Aeneid appears to have been a great success. Virgil is said to have recited Books 2, 4, and 6 to Augustus; and Book 6 apparently caused Augustus' sister Octavia to faint. Although the truth of this claim is subject to scholarly scepticism, it has served as a basis for later art, such as Jean-Baptiste Wicar's Virgil Reading the Aeneid.
What book of the Aeneid is the longest?
A: unanswerable

Context and question: In the case of the ring-porous hardwoods there seems to exist a pretty definite relation between the rate of growth of timber and its properties. This may be briefly summed up in the general statement that the more rapid the growth or the wider the rings of growth, the heavier, harder, stronger, and stiffer the wood. This, it must be remembered, applies only to ring-porous woods such as oak, ash, hickory, and others of the same group, and is, of course, subject to some exceptions and limitations.
If the growth rings are wider, was the growth of the tree slower or more rapid?
Answer: more rapid

Question: In addition to the Vedas, the principal texts of Hinduism, the core themes of the Sanskrit epics Ramayana and Mahabharata are said to have their ultimate origins during this period. The Mahabharata remains, today, the longest single poem in the world. Historians formerly postulated an "epic age" as the milieu of these two epic poems, but now recognize that the texts (which are both familiar with each other) went through multiple stages of development over centuries. For instance, the Mahabharata may have been based on a small-scale conflict (possibly about 1000 BCE) which was eventually "transformed into a gigantic epic war by bards and poets". There is no conclusive proof from archaeology as to whether the specific events of the Mahabharat have any historical basis. The existing texts of these epics are believed to belong to the post-Vedic age, between c. 400 BCE and 400 CE. Some even attempted to date the events using methods of archaeoastronomy which have produced, depending on which passages are chosen and how they are interpreted, estimated dates ranging up to mid 2nd millennium BCE.
Is there an answer to this question: Which Vedic text is the longest single poem on Earth?

Answer: Mahabharata
