Question: The primary site of infection in the lungs, known as the "Ghon focus", is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. Tuberculosis of the lungs may also occur via infection from the blood stream. This is known as a Simon focus and is typically found in the top of the lung. This hematogenous transmission can also spread infection to more distant sites, such as peripheral lymph nodes, the kidneys, the brain, and the bones. All parts of the body can be affected by the disease, though for unknown reasons it rarely affects the heart, skeletal muscles, pancreas, or thyroid.

Question: In Renaissance Europe, from about 1400 onwards, there was a revival of Classical learning accompanied by the development of Renaissance Humanism which placed greater emphasis on the role of the individual in society than had been the case during the Medieval period.

Question: The Samoan islands have been produced by vulcanism, the source of which is the Samoa hotspot which is probably the result of a mantle plume. While all of the islands have volcanic origins, only Savai'i, the western most island in Samoa, is volcanically active with the most recent eruptions in Mt Matavanu (19051911), Mata o le Afi (1902) and Mauga Afi (1725). The highest point in Samoa is Mt Silisili, at 1858 m (6,096 ft). The Saleaula lava fields situated on the central north coast of Savai'i are the result of the Mt Matavanu eruptions which left 50 km (20 sq mi) of solidified lava.
