Q: 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 "QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified."?
A: What can be measured to have a value of zero?

Q: 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 "On February 17, 2010, AF1 announced it would use the "Arena Football League" name.

Q: 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 "As some szlachta were poorer than some non-noble gentry, some particularly impoverished szlachta were forced to become tenants of the wealthier gentry. In doing so, however, these szlachta retained all their constitutional prerogatives, as it was not wealth or lifestyle (obtainable by the gentry), but hereditary juridical status, that determined nobility."?
A: The szlachta did not automatically have this, though they always retained their constitutional prerogatives.

Q: 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 "Several recent movies have been filmed in New Haven, including Mona Lisa Smile (2003), with Julia Roberts, The Life Before Her Eyes (2007), with Uma Thurman, and Indiana Jones and the Kingdom of the Crystal Skull (2008) directed by Steven Spielberg and starring Harrison Ford, Cate Blanchett and Shia LaBeouf. The filming of Crystal Skull involved an extensive chase sequence through the streets of New Haven. Several downtown streets were closed to traffic and received a "makeover" to look like streets of 1957, when the film is set. 500 locals were cast as extras for the film. In Everybody's Fine (2009), Robert De Niro has a close encounter in what is supposed to be the Denver train station; the scene was filmed in New Haven's Union Station."?
A:
Which was produced before 2005, Mona Lisa Smile or Indiana Jones and the Kingdom of the Crystal Skull?
