Question: Passage: In the 1970s, astronomers saw some major advances in astronomical imaging technology, beginning with Antoine Labeyrie's invention of speckle interferometry, a process that significantly reduced the blurring effect caused by astronomical seeing. It increased the optical resolution of ground-based telescopes, allowing for more precise measurements of Betelgeuse's photosphere. With improvements in infrared telescopy atop Mount Wilson, Mount Locke and Mauna Kea in Hawaii, astrophysicists began peering into the complex circumstellar shells surrounding the supergiant, causing them to suspect the presence of huge gas bubbles resulting from convection. But it was not until the late 1980s and early 1990s, when Betelgeuse became a regular target for aperture masking interferometry, that breakthroughs occurred in visible-light and infrared imaging. Pioneered by John E. Baldwin and colleagues of the Cavendish Astrophysics Group, the new technique employed a small mask with several holes in the telescope pupil plane, converting the aperture into an ad-hoc interferometric array. The technique contributed some of the most accurate measurements of Betelgeuse while revealing bright spots on the star's photosphere. These were the first optical and infrared images of a stellar disk other than the Sun, taken first from ground-based interferometers and later from higher-resolution observations of the COAST telescope. The "bright patches" or "hotspots" observed with these instruments appeared to corroborate a theory put forth by Schwarzschild decades earlier of massive convection cells dominating the stellar surface.

Question: Passage: On 19 May 1804, Ney received his Marshal's baton, emblematic of his status as a Marshal of the Empire, the Napoleonic era's equivalent of Marshal of France. In the 1805 campaign, Ney took command of VI Corps of the Grande Armée and was praised for his conduct at Elchingen. In November 1805, Ney invaded the Tyrol, capturing Innsbruck from Archduke John. In the 1806 campaign, Ney fought at Jena and then occupied Erfurt. Later in the campaign, Ney successfully besieged Magdeburg. In the 1807 campaign, Ney arrived with reinforcements in time to save Napoleon from defeat at Eylau, although the battle ended in a draw. Later in the campaign, Ney fought at Güttstadt and commanded the right wing at Friedland. On 6June 1808, Ney was created Duke of Elchingen. In August 1808, he was sent to Spain in command of VI Corps and won a number of minor actions. In 1809, he routed an Anglo-Portuguese force under Sir Robert Wilson at Baños. In 1810, Ney joined Marshal Masséna in the invasion of Portugal, where he took Ciudad Rodrigo from the Spanish and Almeida from the British and Portuguese, brusquely defeated a British force on the River Côa, and fought at Bussaco. During the retreat from Torres Vedras, Ney engaged Wellington's forces in a series of lauded rearguard actions (Pombal, Redinha, Casal Novo, Foz d'Arouce) through which he delayed the pursuing enemy forces long enough to allow the main French force to retreat unmolested. He was ultimately removed from his command for insubordination.

Question: Passage: The first domestic title PAOK won, was the 1971–72 Greek Cup. PAOK eliminated Pierikos, Aias Salamina, local rivals Aris in the quarter-finals with a 2–1 victory at Kleanthis Vikelidis Stadium and progressed to the final with their semi-final victory over Lamia. This time PAOK would face league champions Panathinaikos who also reached the 1971 European Cup Final. The final was played once again in Athens at Georgios Karaiskakis Stadium. PAOK players had 10,000 fans on their side and they vowed that it was about time to return with the trophy at Thessaloniki. It was the sixth final for the Double-Headed Eagle of the North and the fifth time that they traveled to Athens for the trophy match. PAOK won the game 2–1 with Koudas scoring both goals. In the second half, a magnificent bicycle kick of Matzourakis found the net, but the goal was surprisingly disallowed by referee Michas. PAOK triumph and 1st Greek Cup title was widely celebrated by the fans at Thessaloniki.
