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 an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system."?
A: Antennas interact with what?

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 1996, Kerry faced a difficult re-election fight against Governor William Weld, a popular Republican incumbent who had been re-elected in 1994 with 71% of the vote. The race was covered nationwide as one of the most closely watched Senate races that year. Kerry and Weld held several debates and negotiated a campaign spending cap of $6.9 million at Kerry's Beacon Hill townhouse. Both candidates spent more than the cap, with each camp accusing the other of being first to break the agreement. During the campaign, Kerry spoke briefly at the 1996 Democratic National Convention. Kerry won re-election with 53 percent to Weld's 45 percent."?
A: Who won the election in 1996?

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 "Perhaps the most famous raid by Oeselian pirates occurred in 1187, with the attack on the Swedish town of Sigtuna by Finnic raiders from Couronia and Oesel. Among the casualties of this raid was the Swedish archbishop Johannes. The city remained occupied for some time, contributing to its decline as a center of commerce in the 13th century and the rise of Uppsala, Visby, Kalmar and Stockholm. The Livonian Chronicle describes the Oeselians as using two kinds of ships, the piratica and the liburna. The former was a warship, the latter mainly a merchant ship. A piratica could carry approximately 30 men and had a high prow shaped like a dragon or a snakehead and a rectangular sail. Viking-age treasures from Estonia mostly contain silver coins and bars. Saaremaa has the richest finds of Viking treasures after Gotland in Sweden. This strongly suggests that Estonia was an important transit country during the Viking era."?
A: Pirates traveled in?

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 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]"?
A:
At what address did Chopin live until 1830?
