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 "The poor performance of the Portuguese economy was explored in April 2007 by The Economist, which described Portugal as "a new sick man of Europe". From 2002 to 2007, the number of unemployed increased by 65% (270,500 unemployed citizens in 2002, 448,600 unemployed citizens in 2007). By early December 2009, the unemployment rate had reached 10.2% a 23-year record high. In December 2009, ratings agency Standard & Poor's lowered its long-term credit assessment of Portugal to "negative" from "stable," voicing pessimism on the country's structural weaknesses in the economy and weak competitiveness that would hamper growth and the capacity to strengthen its public finances and reduce debt. In July 2011, ratings agency Moody's downgraded its long-term credit assessment of Portugal after warning of deteriorating risk of default in March 2011."?
A: Which ratings agency lowered its long-term credit assessment of Portugal second?

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 "Emperor Zhang's (r. 7588 AD) reign came to be viewed by later Eastern Han scholars as the high point of the dynastic house. Subsequent reigns were increasingly marked by eunuch intervention in court politics and their involvement in the violent power struggles of the imperial consort clans. With the aid of the eunuch Zheng Zhong (d. 107 AD), Emperor He (r. 88105 AD) had Empress Dowager Dou (d. 97 AD) put under house arrest and her clan stripped of power. This was in revenge for Dou's purging of the clan of his natural motherConsort Liangand then concealing her identity from him. After Emperor He's death, his wife Empress Deng Sui (d. 121 AD) managed state affairs as the regent empress dowager during a turbulent financial crisis and widespread Qiang rebellion that lasted from 107 to 118 AD."?
A: Who was He's mother-in-law?

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 "Romila Thapar notes that the division into Hindu-Muslim-British periods of Indian history gives too much weight to "ruling dynasties and foreign invasions", neglecting the social-economic history which often showed a strong continuity. The division into Ancient-Medieval-Modern periods overlooks the fact that the Muslim conquests occurred gradually during which time many things came and went off, while the south was never completely conquered. According to Thapar, a periodisation could also be based on "significant social and economic changes", which are not strictly related to a change of ruling powers.[note 1]"?
A: What can the most recent Indian period be referred to as, without referring to the British?

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 "Video data may be represented as a series of still image frames. The sequence of frames contains spatial and temporal redundancy that video compression algorithms attempt to eliminate or code in a smaller size. Similarities can be encoded by only storing differences between frames, or by using perceptual features of human vision. For example, small differences in color are more difficult to perceive than are changes in brightness. Compression algorithms can average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression. Some of these methods are inherently lossy while others may preserve all relevant information from the original, uncompressed video."?
A:
What are done with the differences?
