question:Please briefly summarize this news article: Ebola outbreak threatens food security in hardest-hit countries The world's worst Ebola epidemic has put harvests at risk and sent food prices soaring in West Africa, the UN Food and Agriculture Organisation (FAO) said on Tuesday, warning the problem would intensify in coming months. The FAO issued a special alert for Liberia, Sierra Leone and Guinea, the three countries most affected by the outbreak, which has killed around 1,550 people since the virus was detected in the remote jungles of southeastern Guinea in March. Restrictions on people's movements and the establishment of quarantine zones to contain the spread of the hemorrhagic fever has led to panic buying, food shortages and price hikes in countries ill-prepared to absorb the shock. "Even prior to the Ebola outbreak, households in some of the most affected areas were spending up to 80 per cent of their incomes on food," said Vincent Martin, head of an FAO unit in Dakar which is coordinating the agency's response. "Now these latest price spikes are effectively putting food completely out of their reach," Martin said in a statement, adding the food crisis could hinder containment of the disease, which is typically spread via the bodily fluids of the sick. Rice and maize production will be scaled back during the fast-approaching main harvest season as migration and movement restrictions cause labour shortages on farms, FAO said. Cash crops like palm oil, cocoa and rubber will be seriously affected, squeezing the purchasing power of many families, who will also lose income and nutrition due to the ban on bush meat. Border crossing closures and the reduction of trade through seaports have tightened food supplies in the three countries, which are all net cereal importers, and propelled prices upwards, exacerbated by higher transport costs. The UN World Food Programme and FAO have approved an emergency program to deliver 65,000 tonnes of food to 1.3 million people affected by Ebola over a three-month period. The price of cassava at a market in the Liberian capital Monrovia rose 150 per cent in the first weeks of August, the FAO said, adding that currency depreciation in Sierra Leone and Liberia was likely to force prices up further. Elsewhere, the World Health Organization said Tuesday that tests show no link between Ebola outbreaks in West Africa and Congo. "Results from virus sequencing of samples from the Ebola outbreak in the Democratic Republic of Congo (DRC) were received last night," WHO said in a statement. "The virus is the Zaire strain, in a lineage most closely related to a virus from the 1995 Ebola outbreak in Kikwit, DRC. "These findings are reassuring, as they exclude the possibility that the virus has spread from West to Central Africa."

question:Teacher:In this task, you're given a context, a sentence, and a character. The sentence describes an action or job of the given character. Also, the context provides more information about the sentence or the character. Your task is to return one of the emotions which are expressed by the Character in the given sentence.

question:Article: Although Foo Fighters continued to be one of the most successful rock acts, with albums like In Your Honor (2005) reaching number two in the US and UK, many of the first wave of post-grunge bands began to fade in popularity. Acts like Creed, Staind, Puddle of Mudd and Nickelback took the genre into the 2000s with considerable commercial success, abandoning most of the angst and anger of the original movement for more conventional anthems, narratives and romantic songs. They were followed in this vein by new acts including Shinedown and Seether. Acts with more conventional hard rock sounds included Andrew W.K., Beautiful Creatures and Buckcherry, whose breakthrough album 15 (2006) went platinum and spawned the single "Sorry" (2007), which made the Top 10 of the Billboard 100. These were joined by bands with hard rock leanings that emerged in the mid-2000s from the garage rock or post punk revival, including Black Rebel Motorcycle Club and Kings of Leon, and Queens of the Stone Age from the US, Three Days Grace from Canada, Jet from Australia and The Datsuns from New Zealand. In 2009 Them Crooked Vultures, a supergroup that brought together Foo Fighters' Dave Grohl, Queens of the Stone Age's Josh Homme and Led Zeppelin bass player John Paul Jones attracted attention as a live act and released a self-titled debut album that reached the top 20 in the US and UK and the top ten in several other countries. Now answer this question: What was the title of Buckcherry's 2007 hit single?

question:What is the title of this article: Cytokinins are a class of plant hormones named for their control of cell division or cytokinesis. The natural cytokinin zeatin was discovered in corn, Zea mays, and is a derivative of the purine adenine. Zeatin is produced in roots and transported to shoots in the xylem where it promotes cell division, bud development, and the greening of chloroplasts. The gibberelins, such as Gibberelic acid are diterpenes synthesised from acetyl CoA via the mevalonate pathway. They are involved in the promotion of germination and dormancy-breaking in seeds, in regulation of plant height by controlling stem elongation and the control of flowering. Abscisic acid (ABA) occurs in all land plants except liverworts, and is synthesised from carotenoids in the chloroplasts and other plastids. It inhibits cell division, promotes seed maturation, and dormancy, and promotes stomatal closure. It was so named because it was originally thought to control abscission. Ethylene is a gaseous hormone that is produced in all higher plant tissues from methionine. It is now known to be the hormone that stimulates or regulates fruit ripening and abscission, and it, or the synthetic growth regulator ethephon which is rapidly metabolised to produce ethylene, are used on industrial scale to promote ripening of cotton, pineapples and other climacteric crops.
