input 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 "One disadvantage of the phalanx was that it was only effective when fighting in large, open spaces, which left the Romans at a disadvantage when fighting in the hilly terrain of central Italian peninsula. In the 4th century BC, the Romans abandoned the phalanx in favour of the more flexible manipular formation. This change is sometimes attributed to Marcus Furius Camillus and placed shortly after the Gallic invasion of 390 BC; it is more likely, however, that they were copied from Rome's Samnite enemies to the south, possibly as a result of Samnite victories during the Second Samnite War (326 to 304 BC)."????
output answer: What didn't the Romans prefer: the phalanx or the manipular formation?

input 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 "Jehovah's Witnesses believe that the Bible condemns the mixing of religions, on the basis that there can only be one truth from God, and therefore reject interfaith and ecumenical movements. They believe that only their religion represents true Christianity, and that other religions fail to meet all the requirements set by God and will soon be destroyed. Jehovah's Witnesses are taught that it is vital to remain "separate from the world." The Witnesses' literature defines the "world" as "the mass of mankind apart from Jehovah's approved servants" and teach that it is morally contaminated and ruled by Satan. Witnesses are taught that association with "worldly" people presents a "danger" to their faith, and are instructed to minimize social contact with non-members to better maintain their own standards of morality."????
output answer: What does the world look like to Witnesses'?

input 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 "Samuel Adelstein described the Lombardi mandolin in 1893 as wider and shorter than the Neapolitan mandolin, with a shallower back and a shorter and wider neck, with six single strings to the regular mandolin's set of 4. The Lombardi was tuned C, D, A, E, B, G. The strings were fastened to the bridge like a guitar's. There were 20 frets, covering three octaves, with an additional 5 notes. When Adelstein wrote, there were no nylon strings, and the gut and single strings "do not vibrate so clearly and sweetly as the double steel string of the Neapolitan.""????
output answer:
which instrument was also mentioned besides the mandolins?
