Question: Which of the empires that succeeded the Achaemenid Empire had the smallest number of people? Passage:Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. The south-western and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People". The Medes unified Iran as a nation and empire in 625 BC. The Achaemenid Empire (550–330 BC), founded by Cyrus the Great, was the first true global superpower state and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire. The Achaemenid Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC. They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.

Question: Who is older, Lisker or the phonetician that he principally worked with? Passage:Leigh Lisker (December 7, 1918 – March 24, 2006) was an eminent American linguist and phonetician. Most of his career was spent at the University of Pennsylvania, where he was a professor and then emeritus professor of linguistics. Dr. Lisker received his A.B. in 1941, with a major in German, his M.A. in 1946, and a Ph.D. in 1949 in linguistics. He was a major figure in phonetics, working both at the University of Pennsylvania and at Haskins Laboratories in New Haven, CT, where he was a senior scientist from 1951 until the end of his life. He collaborated with several phoneticians, principally Arthur S. Abramson. He is best known for his work, done mostly in conjunction with Abramson, on voice onset time. Dr. Lisker also made important contributions to Dravidian linguistics, including the book Introduction to Spoken Telugu (Telugu), and did research comparing phonetic and phonological perceptions on the part of linguistically naive and linguistically sophisticated speakers of different native language backgrounds. He conducted such studies in collaboration with Dr. Abramson of the University of Connecticut, Bh. Krishnamurti  of University of Hyderabad, India, Adrian Fourcin  of University College London, and Mario Rossi  of the Institut de Phonétique at the Université de Provence, Aix-en-Provence.
