Input: Renewable energy commercialization
According to the International Energy Agency, cellulosic ethanol biorefineries could allow biofuels to play a much bigger role in the future than organizations such as the IEA previously thought. Cellulosic ethanol can be made from plant matter composed primarily of inedible cellulose fibers that form the stems and branches of most plants. Crop residues (such as corn stalks, wheat straw and rice straw), wood waste, and municipal solid waste are potential sources of cellulosic biomass. Dedicated energy crops, such as switchgrass, are also promising cellulose sources that can be sustainably produced in many regions.

What is a promising cellulose source that can be sustainably produced in many regions?
Output: Dedicated energy crops

Input: Hard rock
Some established acts continued to enjoy commercial success, such as Aerosmith, with their number one multi-platinum albums: Get a Grip (1993), which produced four Top 40 singles and became the band's best-selling album worldwide (going on to sell over 10 million copies), and Nine Lives (1997). In 1998, Aerosmith released the number one hit "I Don't Want to Miss a Thing", which remains the only single by a hard rock band to debut at number one. AC/DC produced the double platinum Ballbreaker (1995). Bon Jovi appealed to their hard rock audience with songs such as "Keep the Faith" (1992), but also achieved success in adult contemporary radio, with the Top 10 ballads "Bed of Roses" (1993) and "Always" (1994). Bon Jovi's 1995 album These Days was a bigger hit in Europe than it was in the United States, spawning four Top 10 singles on the UK Singles Chart. Metallica's Load (1996) and ReLoad (1997) each sold in excess of 4 million copies in the US and saw the band develop a more melodic and blues rock sound. As the initial impetus of grunge bands faltered in the middle years of the decade, post-grunge bands emerged. They emulated the attitudes and music of grunge, particularly thick, distorted guitars, but with a more radio-friendly commercially oriented sound that drew more directly on traditional hard rock. Among the most successful acts were the Foo Fighters, Candlebox, Live, Collective Soul, Australia's Silverchair and England's Bush, who all cemented post-grunge as one of the most commercially viable subgenres by the late 1990s. Similarly, some post-Britpop bands that followed in the wake of Oasis, including Feeder and Stereophonics, adopted a hard rock or "pop-metal" sound.

What Aerosmith ballad debuted at number one on the charts?
Output: "I Don't Want to Miss a Thing"

Input: Religion in ancient Rome
Human sacrifice in ancient Rome was rare but documented. After the Roman defeat at Cannae two Gauls and two Greeks were buried under the Forum Boarium, in a stone chamber "which had on a previous occasion [228 BC] also been polluted by human victims, a practice most repulsive to Roman feelings". Livy avoids the word "sacrifice" in connection with this bloodless human life-offering; Plutarch does not. The rite was apparently repeated in 113 BC, preparatory to an invasion of Gaul. Its religious dimensions and purpose remain uncertain.

What type of sacrifice was rare in Rome?
Output: Human

Input: Qing dynasty
With Zaifeng gone, Yuan Shikai and his Beiyang commanders effectively dominated Qing politics. He reasoned that going to war would be unreasonable and costly, especially when noting that the Qing government had a goal for constitutional monarchy. Similarly, Sun Yat-sen's government wanted a republican constitutional reform, both aiming for the benefit of China's economy and populace. With permission from Empress Dowager Longyu, Yuan Shikai began negotiating with Sun Yat-sen, who decided that his goal had been achieved in forming a republic, and that therefore he could allow Yuan to step into the position of President of the Republic of China.

Who led the Qing?
Output:
Yuan Shikai
