Question: How long is the Lachlan River? Passage 1:A. Sibiryakov sailed on 28 June 1932 from the Krasny (previously Sobornoy) docks in Arkhangelsk, crossed the Kara Sea and chose a northern, unexplored way around Severnaya Zemlya to the Laptev Sea. In September, after calling at Tiksi and the mouth of the Kolyma, the propeller shaft broke and the icebreaker drifted for 11 days. However, A. Sibiryakov crossed the Chukchi Sea using improvised sails and arrived in the Bering Strait in October. A. Sibiryakov reached the Japanese port of Yokohama after 65 days, having covered more than in the Arctic seas. This was regarded as a heroic feat of Soviet polar seamen and Chief of Expedition Otto Schmidt and Captain Vladimir Voronin were received with many honors at their return to Russia.
 Passage 2:Despite that it was unusual for women to participate in archaeology at the time, in 1901, encouraged by Howard Carter, Lady William Cecil began excavations at Qubbet el-Hawa near Aswan. Her family was wintering in the area and while exploring on the west bank of the Nile had discovered what she thought might be an ancient cemetery. Carter, who in 1899 had been appointed by the Antiquities Service as one of two European Chief Inspectors and in charge of excavations in the Nile Valley south from Qus to the Sudanese border, came to see the find the following day. He arranged for permits to excavate and provided an inspector and workers to assist in the dig. She kept a diary of the details of the expedition in which multiple tombs were found, as well as wooden anthropoid coffins of the Saite Era. Though the entire necropolis was infested with termites, Tomb 21 yielded two burial boxes. The male's coffin disintegrated when it was touched, but the female's coffin remained intact and was removed. The exterior was painted in yellow and devoid of any inscription. The mummy was covered with a blue network of beading. A coarse blue glaze was used on the winged scarabs and Amenti gods depicted on the canopic jars. The sole adornment of the mummy was a one inch by half inch opaque green stone. Lady William's diary recorded that the names found in the tomb were Bao-bao, daughter of Pawebas and Shepentanefet and her brother Waher. She also reported remnants of a former burial, which may have been the tomb of Shepentanefret.
