Question: Matrix groups consist of matrices together with matrix multiplication. The general linear group GL(n, R) consists of all invertible n-by-n matrices with real entries. Its subgroups are referred to as matrix groups or linear groups. The dihedral group example mentioned above can be viewed as a (very small) matrix group. Another important matrix group is the special orthogonal group SO(n). It describes all possible rotations in n dimensions. Via Euler angles, rotation matrices are used in computer graphics.
Try to answer this question if possible: What are matrices and matrix groups combined called?
Answer: unanswerable
Question: Feeding structures in the mouth region vary widely, and have little correlation with the animals' diets. Many polychaetes have a muscular pharynx that can be everted (turned inside out to extend it). In these animals the foremost few segments often lack septa so that, when the muscles in these segments contract, the sharp increase in fluid pressure from all these segments everts the pharynx very quickly. Two families, the Eunicidae and Phyllodocidae, have evolved jaws, which can be used for seizing prey, biting off pieces of vegetation, or grasping dead and decaying matter. On the other hand, some predatory polychaetes have neither jaws nor eversible pharynges. Selective deposit feeders generally live in tubes on the sea-floor and use palps to find food particles in the sediment and then wipe them into their mouths. Filter feeders use "crowns" of palps covered in cilia that wash food particles towards their mouths. Non-selective deposit feeders ingest soil or marine sediments via mouths that are generally unspecialized. Some clitellates have sticky pads in the roofs of their mouths, and some of these can evert the pads to capture prey. Leeches often have an eversible proboscis, or a muscular pharynx with two or three teeth.

Answer: turned inside out to extend
Question: The 1960 Constitution provided for a presidential system of government with independent executive, legislative and judicial branches as well as a complex system of checks and balances including a weighted power-sharing ratio designed to protect the interests of the Turkish Cypriots. The executive was led by a Greek Cypriot president and a Turkish Cypriot vice-president elected by their respective communities for five-year terms and each possessing a right of veto over certain types of legislation and executive decisions. Legislative power rested on the House of Representatives who were also elected on the basis of separate voters' rolls.
Try to answer this question if possible: What types of branches did the 1960 Constitution provide?
Answer: legislative and judicial branches
Question: There are three primary shopping centers in the Bronx: The Hub, Gateway Center and Southern Boulevard. The Hub–Third Avenue Business Improvement District (B.I.D.), in The Hub, is the retail heart of the South Bronx, located where four roads converge: East 149th Street, Willis, Melrose and Third Avenues. It is primarily located inside the neighborhood of Melrose but also lines the northern border of Mott Haven. The Hub has been called "the Broadway of the Bronx", being likened to the real Broadway in Manhattan and the northwestern Bronx. It is the site of both maximum traffic and architectural density. In configuration, it resembles a miniature Times Square, a spatial "bow-tie" created by the geometry of the street. The Hub is part of Bronx Community Board 1.
Try to answer this question if possible: What is The Hub's nickname?
Answer:
"the Broadway of the Bronx"
