Please answer this: What is the answer for the question: What was the first article that spoke of the magnetized compass needle being used? from the following article ? The most important nautical innovation of the Song period seems to have been the introduction of the magnetic mariner's compass, which permitted accurate navigation on the open sea regardless of the weather. The magnetized compass needle known in Chinese as the "south-pointing needle" was first described by Shen Kuo in his 1088 Dream Pool Essays and first mentioned in active use by sailors in Zhu Yu's 1119 Pingzhou Table Talks. There were other considerable advancements in hydraulic engineering and nautical technology during the Song dynasty. The 10th-century invention of the pound lock for canal systems allowed different water levels to be raised and lowered for separated segments of a canal, which significantly aided the safety of canal traffic and allowed for larger barges. There was the Song-era innovation of watertight bulkhead compartments that allowed damage to hulls without sinking the ships. If ships were damaged, the Chinese of the 11th century employed drydocks to repair them while suspended out of the water. The Song used crossbeams to brace the ribs of ships in order to strengthen them in a skeletal-like structure. Stern-mounted rudders had been mounted on Chinese ships since the 1st century, as evidenced with a preserved Han tomb model of a ship. In the Song period, the Chinese devised a way to mechanically raise and lower rudders in order for ships to travel in a wider range of water depths. The Song arranged the protruding teeth of anchors in a circular pattern instead of in one direction. David Graff and Robin Higham state that this arrangement "[made] them more reliable" for anchoring ships.

Please answer this: What is the answer for the question: Who does English's boss think cannot be connected to the crime? from the following article ? Johnny English is a kindhearted but inept MI7 secret agent with dreams of being their most trusted employee. After Agent One dies in a submarine accident unknowingly caused by English, the remaining agents are assassinated via a bombing at Agent One's funeral, leaving English as the lone surviving agent capable of finishing the mission Agent One left when he died. English is assigned to thwart a plot to steal the Crown Jewels, which are on display at the Tower of London. During the display, the power suddenly suffers a blackout and the jewels are stolen. During the chaos, English accidentally knocks out the deputy head of security and pretends to fight an assailant to make up for his mistakes. He later makes up a false description of the "assailant" to MI7 head Pegasus. English and his assistant Angus Bough find that the jewels were removed via a hole dug beneath their display case. The two follow a tunnel where they confront the two thieves Dieter Klein and Klaus Vendetta, who escape in a hearse, with English trying to pursue them but he mistakes another hearse for the escaped vehicle to which he accidentally gatecrashes a funeral until Bough comes to his aid by pretending English is an escaped mental patient. English connects the thieves to Pascal Sauvage, a French prison entrepreneur who helped restore the Crown Jewels. Pegasus finds the claims of his involvement absurd and warns English not to involve Sauvage. In the car park, English and Bough are attacked by Vendetta but are unharmed. English again encounters Lorna in a sushi restaurant as he recognized her pink motorcycle. During their meeting, English is suspicious of her since he has seen her at two of their crime scenes and her records cannot be found on any government computer. English and Bough then decide to break into Sauvage's headquarters via parachutes, but English mistakenly lands on a visually identical tower which turns out to be the City Hospital.

Please answer this: What is the answer for the question: Who were the people that only achieved independence under one leader? from the following article ? Pulakeshin II conquered the eastern Deccan, corresponding to the coastal districts of modern Andhra Pradesh in 616, defeating the remnants of the Vishnukundina kingdom. He appointed his brother Kubja Vishnuvardhana as Viceroy in 621. Thus the Eastern Chalukyas were originally of Kannada stock. After the death of Pulakeshin II, the Vengi Viceroyalty developed into an independent kingdom and included the region between Nellore and Visakhapatnam.After the decline of the Badami Chalukya empire in the mid-8th century, territorial disputes flared up between the Rashtrakutas, the new rulers of the western deccan, and the Eastern Chalukyas. For much of the next two centuries, the Eastern Chalukyas had to accept subordination towards the Rashtrakutas. Apart from a rare military success, such as the one by Vijayaditya II(c.808847), it was only during the rule of Bhima I (c.892921) that these Chalukyas were able to celebrate a measure of independence. After the death of Bhima I, the Andhra region once again saw succession disputes and interference in Vengi affairs by the Rashtrakutas.The fortunes of the Eastern Chalukyas took a turn around 1000. Danarnava, their king, was killed in battle in 973 by the Telugu Choda King Bhima who then imposed his rule over the region for twenty-seven years. During this time, Danarnava's two sons took refuge in the Chola kingdom. Choda Bhima's invasion of Tondaimandalam, a Chola territory, and his subsequent death on the battlefield opened up a new era in CholaChalukya relations. Saktivarman I, the elder son of Danarnava was crowned as the ruler of Vengi in 1000, though under the control of king Rajaraja Chola I. This new relationship between the Cholas and the coastal Andhra kingdom was unacceptable to the Western Chalukyas, who had by then replaced the Rashtrakutas as the main power in the western Deccan. The Western Chalukyas sought to brook the growing Chola influence in the Vengi region but were unsuccessful.Initially, the Eastern Chalukyas had encouraged Kannada language and...
