Problem: Given the question: Vertical lines around which features are emphasised? Answer the above question based on the context below: The woman's hands are crossed tightly as if in prayer, and positioned so low in the painting as to appear to be resting on the frame. They are rendered as tightly compressed into a small area of the picture; it is likely van der Weyden did not want them to result in an area of high tone that might distract from the description of her head. Her slender fingers are minutely detailed; van der Weyden often indicated the social position of his models through his rendering of their face and hands. The sleeve of her dress extends beyond her wrists. Her fingers are folded in layers; their intricate portrayal is the most detailed element in the painting, and echoes the pyramidal form of the upper portion of the painting.Her eyes gaze downward in humility, in contrast to her relatively extravagant clothes. The piety of her expression is achieved through motifs common to van der Weyden's work. Her eyes and nose are elongated and her lower lip made fuller by the use of tone and pronounced finish. Some vertical lines around these features are emphasised, while her pupils are enlarged and her eyebrows slightly raised. In addition the contours of her face are highlighted in a manner that is slightly unnatural and abstract, and outside the usual spatial constraints of 15th-century human representation. This methodology was described by art historian Erwin Panofsky: "Rogier concentrated on certain salient featuressalient both from a physiognomical and psychological point of viewwhich he expressed primarily by lines." Her high forehead and full mouth have been seen as suggestive of a nature at once intellectual, ascetic, and passionate, symbolic of "an unresolved conflict in her personality". Panofsky refers to a "smouldering excitability".The sitter is unknown, although some art historians have speculated on her identity. On the grounds of similarity of facial features, writer Wilhelm Stein suggested in the early 20th century that she might be Marie de Valengin, the illegitimate daughter of Philip the Good of Burgundy....

Problem: Given the question: What animal's underbelly is white to remain camouflaged when something is looking directly up or down at them? Answer the above question based on the context below: Odontocetes are known as toothed whales; they have teeth and only one blowhole. They rely on their well-developed sonar to find their way in the water. Toothed whales send out ultrasonic clicks using the melon. Sound waves travel through the water. Upon striking an object in the water, the sound waves bounce back at the whale. These vibrations are received through fatty tissues in the jaw, which is then rerouted into the ear-bone and into the brain where the vibrations are interpreted. All toothed whales are opportunistic, meaning they will eat anything they can fit in their throat because they are unable to chew. These animals rely on their well-developed flippers and tail fin to propel themselves through the water; they swim by moving their fore-flippers and tail fin up and down. Whale ribs loosely articulate with their thoracic vertebrae at the proximal end, but they do not form a rigid rib cage. This adaptation allows the chest to compress during deep dives as opposed to resisting the force of water pressure. Excluding dolphins and porpoises, odontocetes consist of four families: belugas and narwhals (monodontids), sperm whales (physeterids), dwarf and pygmy sperm whales (kogiids), and beaked whales (ziphiids). There are six species, sometimes referred to as "blackfish", that are dolphins commonly misconceived as whales: the killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, and the two species of pilot whales, all of which are classified under the family Delphinidae (oceanic dolphins).The differences between families of odontocetes include size, feeding adaptations and distribution. Monodontids consist of two species: the beluga and the narwhal. They both reside in the frigid arctic and both have large amounts of blubber. Belugas, being white, hunt in large pods near the surface and around pack ice, their coloration acting as camouflage. Narwhals, being black, hunt in large pods in the aphotic zone, but their underbelly still remains white to remain camouflaged when...

Narwhals

Problem: Given the question: What is the first name of the man whose niece dies? Answer the above question based on the context below: Cattle rustlers Robert Hightower, Pedro "Pete" Rocafuerte, and William Kearney rob a bank in the town of Welcome, Arizona, but William is shot in the shoulder and they have to flee into the desert, pursued by a posse led by Sheriff Buck Sweet, who shoots a hole in their water bag (that they do not notice until after all the water has leaked out). They eventually lose their horses in a desert sandstorm and end up walking. Desperate for water, they head for a water hole, which has, however, been destroyed by the misguided efforts of a bumbling tenderfoot, who then chased after his livestock and did not return. In a covered wagon left nearby lies the man's wife (Sheriff Sweet's niece), who is about to give birth. With the help of the trio, she has a boy, whom she names Robert William Pedro after her benefactors. Before dying, she extracts a promise from them that they will take care of him. Moved, the three desperadoes try to keep their promise despite the acute lack of water. William is certain a higher power guided them there and likens their situation to the Three Magi finding the baby Jesus in a manger. He convinces the others to head for the town of New Jerusalem, which lies across a wide expanse of desert. While crossing a salt flat, William dies; later, Pete falls and breaks his leg. He asks Robert to leave him his pistol, for "protection from coyotes." As Robert walks away, he hears a single gunshot.
