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 theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments. Although Bach did not use equal temperament, as a modern piano is generally tuned, changes in the temperaments from the meantone system, common at the time, to various temperaments that made modulation between all keys musically acceptable, made possible Bach's Well-Tempered Clavier."?
Ans: A keyboard that is not well-tuned is also not well what?

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 Israel Defense Forces is the sole military wing of the Israeli security forces, and is headed by its Chief of General Staff, the Ramatkal, subordinate to the Cabinet. The IDF consist of the army, air force and navy. It was founded during the 1948 ArabIsraeli War by consolidating paramilitary organizationschiefly the Haganahthat preceded the establishment of the state. The IDF also draws upon the resources of the Military Intelligence Directorate (Aman), which works with Mossad and Shabak. The Israel Defense Forces have been involved in several major wars and border conflicts in its short history, making it one of the most battle-trained armed forces in the world."?
Ans: How is it active?

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 "Some paleontologists suggest that animals appeared much earlier than the Cambrian explosion, possibly as early as 1 billion years ago. Trace fossils such as tracks and burrows found in the Tonian period indicate the presence of triploblastic worms, like metazoans, roughly as large (about 5 mm wide) and complex as earthworms. During the beginning of the Tonian period around 1 billion years ago, there was a decrease in Stromatolite diversity, which may indicate the appearance of grazing animals, since stromatolite diversity increased when grazing animals went extinct at the End Permian and End Ordovician extinction events, and decreased shortly after the grazer populations recovered. However the discovery that tracks very similar to these early trace fossils are produced today by the giant single-celled protist Gromia sphaerica casts doubt on their interpretation as evidence of early animal evolution."?
Ans: What condition precipitates the arrival of animals that graze?

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 "Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use."?
Ans: How long has jewelry been made from silver, gold, platinum, and copper?
