PROBLEM: Passage: He was promoted to lieutenant on 23 January 1962, captain on 23 July 1966, and major on 31 December 1972, At this time he was brigade major at HQ 3rd Infantry Brigade in Northern Ireland. As such he was responsible for the efforts to find Captain Robert Nairac who had been abducted by the Provisional IRA. Nairac and Jones had become friends and would sometimes go to the Jones household for supper. After a four-day search, the Garda Síochána confirmed that Nairac had been shot and killed in the Republic of Ireland after being smuggled over the border. On 13 December 1977 he was appointed a Member of the Order of the British Empire (MBE) for his services in Northern Ireland that year. On 30 June 1979 he was promoted lieutenant colonel, and on 1 December 1979, he was transferred to the Parachute Regiment. In the 1981 New Year Honours he was appointed an Officer of the Order of the British Empire (OBE).
 Link Information: Captain Robert Laurence Nairac (31 August 1948 – 15 May 1977) Answer: 14

SOLUTION: How old was Robert Nairac when Jones was promoted to lieutenant? 

PROBLEM: Passage: During April 5, 2017, the Fiji Meteorological Service started to monitor Tropical Disturbance 20F that had developed about to the northwest of the Fijian dependency of Rotuma. The system lied within an area of favourable conditions for further development with low to moderate vertical wind shear and warm sea surface temperatures of about . Over the next couple of days, the system moved south-westwards and gradually developed further, before it was classified as a tropical depression by the FMS during April 7. The United States Joint Typhoon Warning Center (JTWC) subsequently issued a Tropical Cyclone Formation Alert on the disturbance, as atmospheric convection consolidated around the system's elongated low level circulation center. During that day, the system was steered south-westwards towards Vanuatu and New Caledonia, by northeasterly winds located to the northwest of a subtropical ridge of high pressure. The system subsequently passed near or over the islands of Maewo and Ambae, before the JTWC initiated advisories on the depression and designated it as Tropical Cyclone 16P early on April 8. The system subsequently passed near or over Malakula, before the FMS reported that it had developed into a Category 1 tropical cyclone, on the Australian tropical cyclone intensity scale and named it Cook.
 Link Information: Maewo (; formerly Aurora Island) is an island in Vanuatu in Penama province, 105 km to the east of Espiritu Santo.

It is 47 km long, and 6 km wide, with an area of 269 km². Its highest point is 795 m above sea level. In 2009 the island had a population of almost 3,600. Answer: Ambae

SOLUTION: Which of the islands that the cyclone passed over or near has a higher population?

PROBLEM: Passage: After Meissner’s abitur at the Humanistisches Gymnasium, in 1910, he began the study of physics and mathematics at University of Tübingen. After three terms, he went to the University of Munich as a student of the experimentalist Wilhelm Röntgen and the theoretician Arnold Sommerfeld. After one year at Munich, he returned to Tübingen to be able to study spectroscopy with Friedrich Paschen. While still a student in 1914, Meissner was able to prove the existence of oxygen lines in the solar spectrum. He was awarded his doctorate in 1915, on a thesis with the title Interferometrische Wellenlängenbestimmung im infraroten Spektralbereich. In 1916 he became an assistant to Edgar Meyer at the University of Zurich, under whom he completed his Habilitation, in 1918, with the Habilitationsschrift title Untersuchungen des Neonspektrums. The following year, he married the Polish physicist Doctor Janka Kohn.
 Link Information: Spectroscopy is the study of the interaction between matter and electromagnetic radiation  Answer: the interaction between matter and electromagnetic radiation

SOLUTION:
What is the focus of the subject Meissner studied on his return to Tübingen?
