input: Please answer the following: 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 "There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union."?

output: What makes DC an attractive alternative to AC trains?

Please answer this: 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 "Jean-Jacques Rousseau was the first of many to present the Alps as a place of allure and beauty, banishing the prevalent conception of the mountains as a hellish wasteland inhabited by demons. Rousseau's conception of alpine purity was later emphasized with the publication of Albrecht von Haller's poem Die Alpen that described the mountains as an area of mythical purity. Late in the 18th century the first wave of Romantics such as Goethe and Turner came to admire the scenery; Wordsworth visited the area in 1790, writing of his experiences in The Prelude. Schiller later wrote the play William Tell romanticising Swiss independence. After the end of the Napoleonic Wars, the Alpine countries began to see an influx of poets, artists, and musicians, as visitors came to experience the sublime effects of monumental nature."?

Answer: Where might you have heard that the mountains were of a fantastical cleanliness?

Problem: 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 "During the Eocene (56 million years ago - 33.9 million years ago), the continents continued to drift toward their present positions. At the beginning of the period, Australia and Antarctica remained connected, and warm equatorial currents mixed with colder Antarctic waters, distributing the heat around the world and keeping global temperatures high. But when Australia split from the southern continent around 45 Ma, the warm equatorial currents were deflected away from Antarctica, and an isolated cold water channel developed between the two continents. The Antarctic region cooled down, and the ocean surrounding Antarctica began to freeze, sending cold water and ice floes north, reinforcing the cooling. The present pattern of ice ages began about 40 million years ago.[citation needed]"?

A: What did Antarctica and Australia do during the Eocene period?

Could you please come up with a good question for the passage "On Children's Day, June 1, 2008, many parents went to the rubble of schools to mourn for their children. The surviving children, who were mostly living in relief centres, performed ceremonies marking the special day, but also acknowledging the earthquake."?

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 "Total investment in renewable energy (including small hydro-electric projects) was $244 billion in 2012, down 12% from 2011 mainly due to dramatically lower solar prices and weakened US and EU markets. As a share of total investment in power plants, wind and solar PV grew from 14% in 2000 to over 60% in 2012. The top countries for investment in recent years were China, Germany, Spain, the United States, Italy, and Brazil. Renewable energy companies include BrightSource Energy, First Solar, Gamesa, GE Energy, Goldwind, Sinovel, Trina Solar, Vestas and Yingli."????
output answer: Which year saw less growth in the total share of investment in power plants, wind and solar PV: 2000 or 2012?

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 "Mainstream AC itself has evolved in a similar fashion over the years; traditional AC artists like Barbra Streisand, the Carpenters, Dionne Warwick, Barry Manilow, John Denver, and Olivia Newton-John found it harder to have major Top 40 hits as the 1980s wore on, and due to the influence of MTV, artists who were staples of the Contemporary Hit Radio format, such as Richard Marx, Michael Jackson, Bonnie Tyler, George Michael, Phil Collins, and Laura Branigan began crossing over to the AC charts with greater frequency. Collins has been described by AllMusic as "one of the most successful pop and adult contemporary singers of the '80s and beyond". However, with the combination of MTV and AC radio, adult contemporary appeared harder to define as a genre, with established soft-rock artists of the past still charting pop hits and receiving airplay alongside mainstream radio fare from newer artists at the time."????
