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."?

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 "In Renaissance Europe, from about 1400 onwards, there was a revival of Classical learning accompanied by the development of Renaissance Humanism which placed greater emphasis on the role of the individual in society than had been the case during the Medieval period. Buildings were ascribed to specific architects – Brunelleschi, Alberti, Michelangelo, Palladio – and the cult of the individual had begun. There was still no dividing line between artist, architect and engineer, or any of the related vocations, and the appellation was often one of regional preference."?

Rolling Stone magazine was generally impressed with the effort, writing that the album "sound[s] as if it comes from the heart". It resulted in three singles making it to number-one on the Billboard Hot 100: "Live to Tell", "Papa Don't Preach" and "Open Your Heart", and two more top-five singles: "True Blue" and "La Isla Bonita". The album topped the charts in over 28 countries worldwide, an unprecedented achievement at the time, and became her best-selling studio album of her career to this date with sales of 25 million. In the same year, Madonna starred in the critically panned film Shanghai Surprise, for which she was awarded the Golden Raspberry Award for "worst actress". She made her theatrical debut in a production of David Rabe's Goose and Tom-Tom; the film and play both co-starred Penn. The next year, Madonna was featured in the film Who's That Girl. She contributed four songs to its soundtrack, including the title track and "Causing a Commotion"."?
