Question: 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 "In 1931, RCA Victor introduced their vinyl-based Victrolac compound as a material for some unusual-format and special-purpose records. By the end of the 1930s vinyl's advantages of light weight, relative unbreakability and low surface noise had made it the material of choice for prerecorded radio programming and other critical applications. When it came to ordinary 78 rpm records, however, the much higher cost of the raw material, as well as its vulnerability to the heavy pickups and crudely mass-produced steel needles still commonly used in home record players, made its general substitution for shellac impractical at that time. During the Second World War, the United States Armed Forces produced thousands of 12-inch vinyl 78 rpm V-Discs for use by the troops overseas. After the war, the wider use of vinyl became more practical as new record players with relatively lightweight crystal pickups and precision-ground styli made of sapphire or an exotic osmium alloy proliferated. In late 1945, RCA Victor began offering special transparent red vinyl De Luxe pressings of some classical 78s, at a de luxe price. Later, Decca Records introduced vinyl Deccalite 78s, while other record companies came up with vinyl concoctions such as Metrolite, Merco Plastic and Sav-o-flex, but these were mainly used to produce "unbreakable" children's records and special thin vinyl DJ pressings for shipment to radio stations."?

Question: 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 "The institutes of technology and polytechnics have been in existence since at least the 18th century, but became popular after World War II with the expansion of engineering and applied science education, associated with the new needs created by industrialization. The world's first institution of technology, the Berg-Schola (today its legal successor is the University of Miskolc) was founded by the Court Chamber of Vienna in Selmecbanya, Kingdom of Hungary in 1735 in order to train specialists of precious metal and copper mining according to the requirements of the industrial revolution in Hungary. The oldest German Institute of Technology is the Braunschweig University of Technology (founded in 1745 as "Collegium Carolinum"). Another exception is the Ecole Polytechnique, which has educated French elites since its foundation in 1794. In some cases, polytechnics or institutes of technology are engineering schools or technical colleges."?
Answer: What was founded 59 years prior to the school where French elites are trained?

Question: 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 "The French Marines and naval infantry intended for the invasion of northern Germany were dispatched to reinforce the French Army of Chalons and fell into captivity at Sedan along with Napoleon III. A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile. As the autumn storms of the North Sea forced the return of more of the French ships, the blockade of the north German ports diminished and in September 1870 the French navy abandoned the blockade for the winter. The rest of the navy retired to ports along the English Channel and remained in port for the rest of the war."?
