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 "A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high."????
output answer: What important mathematical concept makes a solar balloon not possible for normal flight?

Could you please come up with a good question for the passage "Argentine activists told a news conference that they would not try to snuff out the torch's flame as demonstrators had in Paris and London. "I want to announce that we will not put out the Olympic torch," said pro-Tibet activist Jorge Carcavallo. "We'll be carrying out surprise actions throughout the city of Buenos Aires, but all of these will be peaceful." Among other activities, protesters organized an alternative march that went from the Obelisk to the city hall, featuring their own "Human Rights Torch." A giant banner reading "Free Tibet" was also displayed on the torch route. According to a representative from the NGO 'Human Rights Torch Relay', their objective was to "show the contradiction between the Olympic Games and the presence of widespread human rights violations in China""????
output answer: What did the activists want to achieve?

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 "In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst. In January 2007, screenwriter Jonathan Nolan met with them to discuss adapting Obst and Thorne's treatment into a narrative screenplay. The screenwriter suggested the addition of a "time element" to the treatment's basic idea, which was welcomed by Obst and Thorne. In March of that year, Paramount hired Nolan, as well as scientists from Caltech, forming a workshop to adapt the treatment under the title Interstellar. The following July, Kip Thorne said there was a push by people for him to portray himself in the film. Spielberg later abandoned Interstellar, which was eventually directed by Christopher Nolan."????
output answer: Who wanted Kip to play himself?

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 "Waitz defined anthropology as "the science of the nature of man". By nature he meant matter animated by "the Divine breath"; i.e., he was an animist. Following Broca's lead, Waitz points out that anthropology is a new field, which would gather material from other fields, but would differ from them in the use of comparative anatomy, physiology, and psychology to differentiate man from "the animals nearest to him". He stresses that the data of comparison must be empirical, gathered by experimentation. The history of civilization as well as ethnology are to be brought into the comparison. It is to be presumed fundamentally that the species, man, is a unity, and that "the same laws of thought are applicable to all men"."????
output answer:
Which is not a last name, Waitz or Nature?
