Please answer this: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Quotient groups and subgroups together form a way of describing every group by its presentation: any group is the quotient of the free group over the generators of the group, quotiented by the subgroup of relations. The dihedral group D4, for example, can be generated by two elements r and f (for example, r = r1, the right rotation and f = fv the vertical (or any other) reflection), which means that every symmetry of the square is a finite composition of these two symmetries or their inverses. Together with the relations"?

Could you please come up with a good question for the passage "Detroit's protracted decline has resulted in severe urban decay and thousands of empty buildings around the city. Some parts of Detroit are so sparsely populated that the city has difficulty providing municipal services. The city has considered various solutions, such as demolishing abandoned homes and buildings; removing street lighting from large portions of the city; and encouraging the small population in certain areas to move to more populated locations. While some have estimated 20,000 stray dogs roam the city, studies have shown the true number to be around 1,000-3,000. Roughly half of the owners of Detroit's 305,000 properties failed to pay their 2011 tax bills, resulting in about $246 million in taxes and fees going uncollected, nearly half of which was due to Detroit; the rest of the money would have been earmarked for Wayne County, Detroit Public Schools, and the library system."?

Could you please come up with a good question for the passage "Sanskrit (/snskrt/; Sanskrit: samskrtam [smskrtm] or samskrta, originally samskrta vak, "refined speech") is the primary sacred language of Hinduism, a philosophical language in Buddhism, Hinduism, Sikhism and Jainism, and a literary language that was in use as a lingua franca in Greater India. It is a standardised dialect of Old Indo-Aryan, originating as Vedic Sanskrit and tracing its linguistic ancestry back to Proto-Indo-Iranian and Proto-Indo-European. Today it is listed as one of the 22 scheduled languages of India and is an official language of the state of Uttarakhand. As one of the oldest Indo-European languages for which substantial written documentation exists, Sanskrit holds a prominent position in Indo-European studies."?
