In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: What part of an insect's internal organs is chambered?, 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.:6165 Air is taken in through openings on the sides of the abdomen called spiracles.
[A]: dorsal tube

[Q]: How did the pope respond to the request?, Context: Neither John nor the rebel barons seriously attempted to implement the peace accord. The rebel barons suspected that the proposed baronial council would be unacceptable to John and that he would challenge the legality of the charter; they packed the baronial council with their own hardliners and refused to demobilise their forces or surrender London as agreed. Despite his promises to the contrary, John appealed to Innocent for help, observing that the charter compromised the pope's rights under the 1213 agreement that had appointed him John's feudal lord. Innocent obliged; he declared the charter "not only shameful and demeaning, but illegal and unjust" and excommunicated the rebel barons. The failure of the agreement led rapidly to the First Barons' War.
[A]: obliged

[Q]: Which of the following words is least related to the others: hyem, home, barn or hjem?, Context: "Bairn" and "hyem", meaning "child" and "home", respectively, are examples of Geordie words with origins in Scandinavia; barn and hjem are the corresponding modern Norwegian and Danish words. Some words used in the Geordie dialect are used elsewhere in the Northern United Kingdom. The words "bonny" (meaning "pretty"), "howay" ("come on"), "stot" ("bounce") and "hadaway" ("go away" or "you're kidding"), all appear to be used in Scots; "aye" ("yes") and "nowt" (IPA://nat/, rhymes with out,"nothing") are used elsewhere in Northern England. Many words, however, appear to be used exclusively in Newcastle and the surrounding area, such as "Canny" (a versatile word meaning "good", "nice" or "very"), "hacky" ("dirty"), "netty" ("toilet"), "hoy" ("throw", from the Dutch gooien, via West Frisian), "hockle" ("spit").
[A]:
barn
