Input: Read this: In December 1831, he joined the Beagle expedition as a gentleman naturalist and geologist. He read Charles Lyell's Principles of Geology and from the first stop ashore, at St. Jago, found Lyell's uniformitarianism a key to the geological history of landscapes. Darwin discovered fossils resembling huge armadillos, and noted the geographical distribution of modern species in hope of finding their "centre of creation". The three Fuegian missionaries the expedition returned to Tierra del Fuego were friendly and civilised, yet to Darwin their relatives on the island seemed "miserable, degraded savages", and he no longer saw an unbridgeable gap between humans and animals. As the Beagle neared England in 1836, he noted that species might not be fixed.
Question: Who wrote The Principles of Geology?

Output: Charles Lyell


QUES: According to the commentators, Virgil received his first education when he was five years old and he later went to Cremona, Milan, and finally Rome to study rhetoric, medicine, and astronomy, which he soon abandoned for philosophy. From Virgil's admiring references to the neoteric writers Pollio and Cinna, it has been inferred that he was, for a time, associated with Catullus' neoteric circle. However schoolmates considered Virgil extremely shy and reserved, according to Servius, and he was nicknamed "Parthenias" or "maiden" because of his social aloofness. Virgil seems to have suffered bad health throughout his life and in some ways lived the life of an invalid. According to the Catalepton, while in the Epicurean school of Siro the Epicurean at Naples, he began to write poetry. A group of small works attributed to the youthful Virgil by the commentators survive collected under the title Appendix Vergiliana, but are largely considered spurious by scholars. One, the Catalepton, consists of fourteen short poems, some of which may be Virgil's, and another, a short narrative poem titled the Culex ("The Gnat"), was attributed to Virgil as early as the 1st century AD.

Where did Pollio live?

QUES: The Gurjar Pratihar Empire acted as a barrier for Arab invaders from the 8th to the 11th century. The chief accomplishment of the Gurjara Pratihara empire lies in its successful resistance to foreign invasions from the west, starting in the days of Junaid. Historian R. C. Majumdar says that this was openly acknowledged by the Arab writers. He further notes that historians of India have wondered at the slow progress of Muslim invaders in India, as compared with their rapid advance in other parts of the world. Now there seems little doubt that it was the power of the Gurjara Pratihara army that effectively barred the progress of the Arabs beyond the confines of Sindh, their first conquest for nearly 300 years.
Arab conquest was limited to what region?

ANS: Sindh

Input: Read this: Labour has long been identified with red, a political colour traditionally affiliated with socialism and the labour movement. The party conference in 1931 passed a motion "That this conference adopts Party Colours, which should be uniform throughout the country, colours to be red and gold". Since the party's inception, the red flag has been Labour's official symbol; the flag has been associated with socialism and revolution ever since the 1789 French Revolution and the revolutions of 1848.
