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.

Question: How many named storms were there in the season that Cyclone Chapala was the third named storm? Passage:Extremely Severe Cyclonic Storm Chapala (, iiesar tashabalaan; ) was a powerful tropical cyclone which caused moderate damage in Yemen during November 2015. The third named storm of the 2015 North Indian Ocean cyclone season, it developed on 28 October off western India from the monsoon trough. Fueled by record warm water temperatures, the system quickly intensified and was named Chapala by the India Meteorological Department (IMD). By 30 October, the storm developed an eye in the center of a well-defined circular area of deep convection. That day, the IMD estimated peak three-minute sustained winds of 215 km/h (130 mph), and the JTWC estimated one-minute winds of 240 km/h (150 mph); only Cyclone Gonu in 2007 and Cyclone Kyarr in 2019 was stronger in the Arabian Sea.

Question: How many years were there between the re-forming of the 20 Battery Royal Artillery and the beginning of the Cuban missile crisis? Passage:After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
