Problem: Extract the answer to the question from the following context. Question: What part of an insect is analogous to the heart in humans? Context: Insect respiration is accomplished without lungs. Instead, the insect respiratory system uses a system of internal tubes and sacs through which gases either diffuse or are actively pumped, delivering oxygen directly to tissues that need it via their trachea (element 8 in numbered diagram). Since oxygen is delivered directly, the circulatory system is not used to carry oxygen, and is therefore greatly reduced. The insect circulatory system has no veins or arteries, and instead consists of little more than a single, perforated dorsal tube which pulses peristaltically. Toward the thorax, the dorsal tube (element 14) divides into chambers and acts like the insect's heart. The opposite end of the dorsal tube is like the aorta of the insect circulating the hemolymph, arthropods' fluid analog of blood, inside the body cavity.:61–65 Air is taken in through openings on the sides of the abdomen called spiracles.

A: dorsal tube


Problem: Extract the answer to the question from the following context. Question: Who ruled alongside the Dalai Lama? Context: Soon after the victory in Ü-Tsang, Güshi Khan organized a welcoming ceremony for Lozang Gyatso once he arrived a day's ride from Shigatse, presenting his conquest of Tibet as a gift to the Dalai Lama. In a second ceremony held within the main hall of the Shigatse fortress, Güshi Khan enthroned the Dalai Lama as the ruler of Tibet, but conferred the actual governing authority to the regent Sonam Chöpel. Although Güshi Khan had granted the Dalai Lama "supreme authority" as Goldstein writes, the title of 'King of Tibet' was conferred upon Güshi Khan, spending his summers in pastures north of Lhasa and occupying Lhasa each winter. Van Praag writes that at this point Güshi Khan maintained control over the armed forces, but accepted his inferior status towards the Dalai Lama. Rawski writes that the Dalai Lama shared power with his regent and Güshi Khan during his early secular and religious reign. However, Rawski states that he eventually "expanded his own authority by presenting himself as Avalokiteśvara through the performance of rituals," by building the Potala Palace and other structures on traditional religious sites, and by emphasizing lineage reincarnation through written biographies. Goldstein states that the government of Güshi Khan and the Dalai Lama persecuted the Karma Kagyu sect, confiscated their wealth and property, and even converted their monasteries into Gelug monasteries. Rawski writes that this Mongol patronage allowed the Gelugpas to dominate the rival religious sects in Tibet.

A: his regent and Güshi Khan


Problem: Extract the answer to the question from the following context. Question: What was the purported intent of showing the Ten Commandments on the grounds of the courthouse? Context: On December 20, 2005, the United States Court of Appeals for the Sixth Circuit ruled in the case of ACLU v. Mercer County that the continued display of the Ten Commandments as part of a larger display on American legal traditions in a Kentucky courthouse was allowed, because the purpose of the display (educating the public on American legal traditions) was secular in nature. In ruling on the Mount Soledad cross controversy on May 3, 2006, however, a federal judge ruled that the cross on public property on Mount Soledad must be removed.

A: educating the public on American legal traditions


Problem: Extract the answer to the question from the following context. Question: __ sat for Morbihan. Context: Although public opinion in Paris was strongly against any form of surrender or concession to the Prussians, the Government realised that it could not hold the city for much longer, and that Gambetta's provincial armies would probably never break through to relieve Paris. President Trochu resigned on 25 January and was replaced by Favre, who signed the surrender two days later at Versailles, with the armistice coming into effect at midnight. Several sources claim that in his carriage on the way back to Paris, Favre broke into tears, and collapsed into his daughter's arms as the guns around Paris fell silent at midnight. At Tours, Gambetta received word from Paris on 30 January that the Government had surrendered. Furious, he refused to surrender and launched an immediate attack on German forces at Orleans which, predictably, failed. A delegation of Parisian diplomats arrived in Tours by train on 5 February to negotiate with Gambetta, and the following day Gambetta stepped down and surrendered control of the provincial armies to the Government of National Defence, which promptly ordered a cease-fire across France.

A:
Trochu
