The answer to the question: Who did the Song Dynasty alternate between warfare and diplomacy with? is inside the article: After usurping the throne of the Later Zhou dynasty, Emperor Taizu of Song (r. 960–976) spent sixteen years conquering the rest of China, reuniting much of the territory that had once belonged to the Han and Tang empires and ending the upheaval of the Five Dynasties and Ten Kingdoms period. In Kaifeng, he established a strong central government over the empire. The establishment of this capital marked the start of the Northern Song period. He ensured administrative stability by promoting the civil service examination system of drafting state bureaucrats by skill and merit (instead of aristocratic or military position) and promoted projects that ensured efficiency in communication throughout the empire. In one such project, cartographers created detailed maps of each province and city that were then collected in a large atlas. Emperor Taizu also promoted groundbreaking scientific and technological innovations by supporting such works as the astronomical clock tower designed and built by the engineer Zhang Sixun.The Song court maintained diplomatic relations with Chola India, the Fatimid Caliphate of Egypt, Srivijaya, the Kara-Khanid Khanate of Central Asia, the Goryeo kingdom in Korea, and other countries that were also trade partners with Japan. Chinese records even mention an embassy from the ruler of "Fu lin" (拂菻, i.e. the Byzantine Empire), Michael VII Doukas, and its arrival in 1081. However, China's closest neighbouring states had the greatest impact on its domestic and foreign policy. From its inception under Taizu, the Song dynasty alternated between warfare and diplomacy with the ethnic Khitans of the Liao dynasty in the northeast and with the Tanguts of the Western Xia in the northwest. The Song dynasty used military force in an attempt to quell the Liao dynasty and to recapture the Sixteen Prefectures, a territory under Khitan control since 938 that was traditionally considered to be part of China proper (Most parts of today's Beijing and Tianjin). Song forces were repulsed by the Liao forces, who..., can you guess it ?

Answer: the ethnic Khitans of the Liao dynasty


The answer to the question: Between what years was the burial tomb of Structure 7A created? is inside the article: A Late Preclassic tomb has been excavated, believed to be a royal burial. This tomb has been designated Burial 1; it was found during excavations of Structure 7A and was inserted into the centre of this Middle Preclassic structure. The burial is also associated with Stela 13 and with a massive offering of more than 600 ceramic vessels and other artifacts found at the base of Structure 7A. These ceramics date the offering to the end of the Late Preclassic. No human remains have been recovered but the find is assumed to be a burial due to the associated artifacts. The body is believed to have been interred upon a litter measuring 1 by 2 metres (3.3 by 6.6 ft), which was probably made of wood and coated in red cinnabar dust. Grave goods include an 18-piece jade necklace, two earspools coated in cinnabar, various mosaic mirrors made from iron pyrite, one consisting of more than 800 pieces, a jade mosaic mask, two prismatic obsidian blades, a finely carved greenstone fish, various beads that presumably formed jewellery such as bracelets and a selection of ceramics that date the tomb to AD 100–200.In October 2012, a tomb carbon-dated between 700 BC and 400 BC was reported to have been found in Takalik Abaj of a ruler nicknamed K'utz Chman ("Grandfather Vulture" in Mam) by archaeologists, a sacred king or "big chief" who "bridged the gap between the Olmec and Mayan cultures in Central America," according to Miguel Orrego. The tomb is suggested to be the oldest Maya royal burial to have been discovered so far., can you guess it ?

The answer to the question: What is the thing or person that may be immune to the venom of the Lycosa Carnivora? is inside the article: Consulting detective Sherlock Holmes fakes his own death in Scotland in order to investigate a number of bizarre apparent suicides that he is convinced are part of an elaborate plot by "a female Moriarty". Returning to his assistant Watson in secret, Holmes notes that all the victims were wealthy gamblers, so disguised as "Rajni Singh", a distinguished Indian officer, he stalks London's gaming clubs. It is not long before he encounters the villain of the piece, Adrea  Spedding. Holmes discovers that she seeks out men short of money, persuades them to pawn their life insurance policies with her accomplices, then kills them. Holmes sets himself up as her next victim, discovering that she uses the deadly spider, Lycosa Carnivora, whose venom causes such excruciating pain that the victims kill themselves. Holmes also finds the footprint of a child nearby. Searching for evidence Holmes and Watson visit eminent arachnologist Matthew Ordway, who may have supplied the deadly creatures. Holmes soon realizes that the man he is speaking to is an impostor, but the villain makes his escape. Searching the premises, Holmes finds the corpse of the real Ordway, as well as his journals, which allude to something or someone from Central Africa immune to the spider venom. This baffles Holmes until he finds the model skeleton of a child. However, Dr. Watson points out that the relation of the skull and the circumference of the chest prove it is not a child, and Holmes deduces that the Central African thing described in the journal is a pygmy. Holmes and Watson continue their investigations at a nearby fairground, where Holmes allows himself to fall into the clutches of Spedding and her gang. Bound and gagged, Holmes is tied behind a moving target in a shooting gallery, at which Lestrade and Watson take pot shots with a  .22 rifle. However Holmes manages to escape, and Lestrade and the police arrest Spedding, her gang, and the pygmy., can you guess it ?
