Q: Passage: Medieval Kraków was surrounded by a 1.9 mile (3 km) defensive wall complete with 46 towers and seven main entrances leading through them. The fortifications around the Old Town were erected over the course of two centuries. The current architectural plan of Stare Miasto—the 13th-century merchants' town—was drawn up following the Tatar invasions of 1259 and 1287. It features the centrally located Rynek Główny, or Main Square, the largest medieval town square of any European city. There is a number of historic landmarks in its vicinity, such as St. Mary's Basilica (Kościół Mariacki), Church of St. Wojciech (St. Adalbert's), Church of St. Barbara, as well as other national treasures. At the center of the plaza, surrounded by kamienice (row houses) and noble residences, stands the Renaissance cloth hall Sukiennice (currently housing gift shops, restaurants and merchant stalls) with the National Gallery of Art upstairs. It is flanked by the Town Hall Tower (Wieża ratuszowa).

Q: Passage: Within the cemetery, there are special sections allocated to graves of the participants of Polish national uprisings such as the November Uprising, the January Uprising and the Kraków Uprising. First World War casualties are buried there, including ethnically Polish soldiers conscripted into all three imperial armies: Austrian, Russian and Prussian – most of whom died in local hospitals. There are members of Polish Legions; the participants of the Charge at Rokitna; the workers killed during strikes of 1936; Second World War casualties including soldiers of the Polish September campaign of 1939. All Allied pilots shot down over Poland are buried here, including those originally buried in Warsaw, along with hundreds of Commonwealth of Nations casualties and prisoners of war who died during the German occupation; the latter brought together by the BAOR into a Commonwealth plot containing a Cross of Sacrifice. Polish partisans, the victims of Nazi crimes; and Soviet soldiers who died during their anti-German attack on Kraków in 1945, are buried here.

Q: Passage: Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.
