Example Input: San Francisco (CNN) -- As Nokia prepares for its next crucial venture into the U.S. and high-end smartphones, the Finnish cell-phone maker is missing a crucial piece: an abundant catalog of applications. Nokia is attempting to woo app developers with such incentives as pre-installing their software on the forthcoming phone, prominent promotion for their products and funding development of an app, according to three people involved in the negotiations. A vibrant app store has become a major selling point to smartphone customers. In the past, Nokia, which sells the highest volume of mobile phones worldwide, has made efforts to work with some creators of apps for its platforms. A Nokia spokeswoman said the company offers app developers a variety of incentives, some in partnership with Microsoft, which include coding assistance and marketing. "We do not disclose these arrangements, as each is different," she said. Microsoft declined to comment for this story.Nokia is offering to pay developers to make apps for its new phone, sources saySuch payments from phone manufacturers are unusualMicrosoft did something similar last year, but its Windows Phone app catalog is still lackingNokia is set to launch its first Windows phone by the end of the year, sources say

Example Input: Tampa, Florida (CNN) -- With Texas Gov. Rick Perry threatening to cement his standing atop the national polls, his rivals for the Republican presidential nomination aggressively sought to undermine his conservative credentials on Monday during the first-ever CNN/Tea Party debate in Florida. Perry repeatedly found himself in the crosshairs, as the field of candidates took turns attacking his positions on illegal immigration, Social Security, and his controversial 2007 push to vaccinate Texas schoolgirls against human papillomavirus, a common sexually transmitted disease that can lead to cervical cancer. Minnesota Rep. Michele Bachmann, whose standing among Republicans has slipped dramatically since Perry entered the race, said she was "offended" by Perry's executive order, which included an opt-out provision for parents who did not want the vaccine.NEW: Perry finds himself in the crosshairs as GOP candidates attack his positionsBachmann accuses Perry of helping a drug company through a vaccination orderRomney on Perry: Being dealt aces does not make a good poker playerPerry calls for Social Security reform but drops "Ponzi scheme" label

Example Input: Havana (CNN) U.S. President Barack Obama put the authoritarian government in Havana on the spot Monday, taking questions from reporters and insisting that his Cuban counterpart also deliver answers to pointed queries on human rights, political prisoners and economic reforms. Though they both acknowledged deep disagreements on these issues, the two leaders found common ground on the topic of the economic embargo on Cuba, which both want lifted.
