Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Example Input: "We don't necessarily believe that new advertising, which might make consumers feel better about the Coke brand or better about the ads themselves , will actually result in consumers consuming more of the product," Morgan Stanley's Bill Pecoriello wrote in a research note the days after the investor meeting . But Coke is optimistic it can regain its old magic, and is banking on a new slogan: "Welcome to the Coke side of life." BREAK THROUGH HIT? With PepsiCo about to surpass Coke as the beverage king on Wall Street--Pepsi's market capitalization has _ in recent years to $97.9 billion, putting it less than a billion dollars behind its rival--the heat is on Coke . It's set to launch a new marketing campaign in March, 2006. And having taken a quick look at Coke's investor presentation on Dec. 7 in New York, my sense is that Coke may be moving in the right direction . Given the continued shift by consumers away from soda--Coke's stronghold --and into alternative beverages like juice, tea, and water, Coke badly needs a breakthrough hit. And given that shift away from soda, some analyists wonder whether even the catchiest new ads will be enough to put the fizz back into Coke. SAME OLD, UPDATED? The new flavors of PowerAde sports drink will probably enable Coke to continue stealing market share from PepsiCo's Gatorade brand. And Coke is getting a little more creative with packaging, including new, aluminum bottles of Coke that will be sold in nightclubs, and an 8.4-ounce "100 calorie" version of its flagship Coke that will appeal to women who want fewer calories and will like the fact that the small can will fit in their purse. I doubt whether other new products will be successful, including a new coffee-flavored soda called Coke-Cola Black that I tried. Think carbonated coffee. But I'm not sure if the product, which Coke is pitching as an afternoon pick-me-up for the 35-and-over set, is going to pull people away from their afternoon Frappucino fix. And my opinion is that Vault, an orange-flavored energy drink, will have just as much trouble unseating Mountain Dew among teens as did Coke's last attempt, a product called Surge. If there is one concern I have about the fresh offerings Coke plans to launch this year, it appears that many of them are simply new brands, not new products.
Example Output: When the middle-aged people feel tired, what would they prefer to drink in order to continue their work?

Example Input: It is generally accepted that the mitochondria play central roles in energy production of most eukaryotes. In contrast, it has been thought that Plasmodium spp., the causative agent of malaria, rely mainly on cytosolic glycolysis but not mitochondrial oxidative phosphorylation for energy production during blood stages. However, Plasmodium spp. possesses all genes necessary for the tricarboxylic acid (TCA) cycle and most of the genes for electron transport chain (ETC) enzymes. Therefore, it remains elusive whether oxidative phosphorylation is essential for the parasite survival. To elucidate the role of TCA metabolism and ETC in malaria parasites, we deleted the gene for flavoprotein (Fp) subunit, Pbsdha, one of four components of complex II, a catalytic subunit for succinate dehydrogenase activity. The Pbsdha(-) parasite grew normally at blood stages in mouse. In contrast, ookinete formation of Pbsdha(-) parasites in the mosquito stage was severely impaired. Finally, Pbsdha(-) ookinetes failed in oocyst formation, leading to complete malaria transmission blockade. These results suggest that malaria parasite may switch the energy metabolism from glycolysis to oxidative phosphorylation to adapt to the insect vector where glucose is not readily available for ATP production.
Example Output: Which is the causative agent of malaria?

Example Input: The Rebellion was the career highlight for both leaders; Cumberland resigned from the Army in 1757 and died of a stroke in 1765. Charles was initially treated as a hero on his return to Paris but the Stuarts were once again barred from France by the 1748 Treaty of Aix-la-Chapelle. Henry Stuart's entry into the Catholic Church in June 1747 was seen as tacit acceptance the Jacobites were finished and Charles never forgave him. He continued attempts to reignite the cause, including a secret visit to London in 1750 but habitual heavy drinking made him argumentative and hard to work with. In 1759, he met French Chief Minister de Choiseul to discuss another invasion attempt but Choiseul dismissed him as incapable through drink. When his father James died in 1766, Pope Clement XIII refused to recognise him as Charles III, despite the strong objections of his brother Henry. Charles never visited Britain again and died in Rome in January 1788, a disappointed and embittered man.
Example Output:
Which happened first, Charles secret visit to London or his meeting with French Chief Minister de Choiseul?
