Example Input: Paragraph: "With abortion now a key issue in the debate over health care reform, abortion rights supporters are highlighting President Barack Obama's promise about the issue during the presidential campaign. In an alert to members on Nov. 9, 2009, Planned Parenthood Action Fund said, ""President Obama campaigned on a promise to put reproductive health care at the center of his reform plan."" We'll address that claim here. We'll also be adding it to our Obameter database of campaign promises. The group's claim is virtually identical to one made in September by House Republican Leader John Boehner, R-Ohio, who said in a statement that, ""during his quest for the presidency, now-President Obama declared that everyone deserves access to reproductive health care that includes abortion, and vowed that this 'right' would be at the heart of his health care reform plan if elected president."" We researched Boehner's claim and concluded he was right about Obama's promise. To explore Obama's promise on abortion coverage in his health care plan, you need to go back to a July 17, 2007, speech he gave to the Planned Parenthood Action Fund. In that speech, he discussed his commitment to how ""reproductive care"" -- a term a campaign aide said included abortion coverage -- would fit into his health care reform plan. Obama said, ""In my mind, reproductive care is essential care. It is basic care, so it is at the center and at the heart of the plan that I propose. Essentially what we're doing is, we're going to set up a public plan that all persons and all women can access if they don't have health insurance. It will be a plan that will provide all essential services, including reproductive services, as well as mental health services and disease management services, because part of our interest is to make sure that we're putting more money into preventive care."" The words Obama used in that speech mirror those in the Planned Parenthood Action Fund's recent alert even more closely than they did Boehner's formulation. So it's certainly correct, as the group says, that Obama ""campaigned on a promise to put reproductive health care at the center of his reform plan."" It's worth nothing that since he spoke to that group -- an important constituency for someone seeking the Democratic nomination -- he has chosen his words carefully. Of all the words Obama has spoken and written about health care reform since 2007 -- a voluminous amount, to be sure -- the terms ""abortion"" and ""reproductive health"" haven't popped up very often. Indeed, on several of the rare occasions in which Obama or his staff have broached the subject, it's been to assure Americans that his health care proposal would not promote abortions. For instance, in his prime-time address to Congress on Sept. 9, 2009, Obama's only mention of abortion -- which came immediately after he was interrupted by the heckling Rep. Joe Wilson, R-S.C. -- was that ""one more misunderstanding I want to clear up: Under our plan, no federal dollars will be used to fund abortions, and federal conscience laws will remain in place."" That's a reflection of the sensitivity surrounding the issue. Obama's promise to the abortion rights group during the primary campaign could now be a liability before a broader audience that includes many people opposed to abortion rights. Still, Planned Parenthood is correct that Obama campaigned on a promise that he would put reproductive health care at the center of his reform plan."" After all, he was speaking to . . . Planned Parenthood. So we find the group's claim to be ." Claim: President Obama campaigned on a promise to put reproductive health care at the center of his reform plan.
Example Output: "Planned Parenthood says Obama promised to ""put reproductive health care at the center"" of health reform"

Example Input: Paragraph: Yet nothing prepared residents of its oldest town, Graaff-Reinet, for their worst drought in more than a century. As the dry spell entered its fourth year, tap water turned brown and smelled like rotting fish. When the water behind the Nqweba Dam dried up, depositing tens of thousands of dead fish onto cracked earth, queues began forming at municipal bore holes and farm animals died in their hundreds. The bleak choices facing millions of people in drought-stricken southern Africa - whether to flush toilets or not, or to keep animals alive or let them die - could soon be faced by other places on a warming planet with shrinking water supplies. "This area is dry but our taps have never been completely empty. Never," said Bukelwa Booysen, who has had to send staff in search of borehole water for her school for disabled children, and send the kids home when they can't find any. An abnormally hot summer with rainfall 75% below average, according to the U.S. National Oceanic and Atmospheric Administration, has struck the whole region. The United Nations says 45 million people in southern Africa face hunger. Bushes and trees clinging to the Karoo's rocky ravines are withered and grey - even hardy acacia thorns are dying. Signs mark rivers that are now dry beds. At one farm, Gerrie Snyman, 65, was feeding grain to sheep and goats that couldn't find pasture. More than a third of his couple-thousand goats and sheep had either died or been sold this year. His 80 cows were now 15. He loaded a calf that was starving - its mother had stopped producing milk - onto his truck to take home and shoot. A friend had shot himself dead after his animals died of thirst. "We are grateful to the Almighty for our borehole water," he said. "We don't know what we'll do when it runs out." When Cape Town's reservoir nearly ran dry 18 months ago, it made international headlines and authorities rationed water. Yet Karoo is long past water rationing. For Valentia Esho, 45, an unemployed mother of seven in the township of Umazisakhe, it means letting her toilet fill up instead of flushing, never washing clothes and only washing plates that stink. Water is just for drinking. "The house is really smelling," she said, inside her one-room brick-and-tin home. "Everyone is paining from stomach aches and diarrhoea." In another township, Asherville, where wind kicked up dust devils, school headmaster Basil Vaaltyn was overseeing water distribution from a truck. He'd done everything to cut down on his usage: "I'm down to a minute showering instead of two." His wife saves dirty dishwater to fill the cistern. A spokesman for the municipality said it was drilling boreholes, installing pipelines and building an 18-million-litre reservoir, adding: "Usage of water is still very high. The community is requested to use water sparingly." With municipal authorities overwhelmed, South African charity Gift of the Givers is trucking water to townships and drilling boreholes. Gideon Groenewald, a geohydrologist for the charity, uses science and spirituality to look for groundwater. When he was growing up on a farm, he used to dowse with wet twigs. Nowadays he prefers magnetic detectors. "I open Google maps and look for the lines of trees. I ask God in prayer which lines hold water, then I go down to that GPS location," he said while a forked stick turned in his hand over an arid patch of shrubs. "You see the stick moving where the magnetic field is? There's water here," he continued. "It's pure science." The charity has drilled 1,800 boreholes in the past three years, Groenewald said, only a third of them dry. But Louise Stafford, water director for the Nature Conservancy in South Africa, urged caution with boreholes, because groundwater is a finite resource. Water-intensive agriculture like citrus farms can make droughts worse, she said, and leaky pipes are losing a billion litres a year - problems Water Minister Lindiwe Sisulu pledged to tackle in a new water masterplan she delivered on Thursday. One Sunday, as clouds formed over Graaff-Reinet, its Assembly Church prayed. The clouds spat but didn't pour. "We pray for God to open heaven and send rain," Pastor Dolan Cochrane said. The congregation bowed. "Lord," Cochrane continued. "We know that, in your time, you will come to our rescue." Claim: South Africa's Karoo drills and prays as taps run dry.
Example Output: South Africa's Karoo region has always been parched - it means land of thirst in the language of its earliest inhabitants, the Khoisan hunter gatherers.

Example Input: Paragraph: Its ACI-35 vaccine aims to stimulate the immune system to produce antibodies which target the tau protein that forms twisted fibers and tangles inside the brain. Many scientists believe tau is an important cause of Alzheimer's, alongside another protein known as amyloid, that has been the main focus of drug development efforts so far. Although there is still no treatment that can effectively modify the disease or slow its progression, a number of big pharma companies - including Roche, Eli Lilly, Merck & Co and Johnson & Johnson - are pursuing a variety of approaches to get to the root cause. AC Immune's most advanced Alzheimer's drug is the anti-Abeta antibody crenezumab which it licensed to Roche's subsidiary Genentech in 2006. Results of a Phase II trial of crenezumab are expected in the first half of this year and will be crucial for the company's next steps. "At the moment we are keeping all options open," Chief Executive Andrea Pfeifer said in a telephone interview, adding that the company would consider an initial public offering in the United States as an option. Earlier on Thursday, AC Immune said it had completed a fourth round of financing, raising 20 million Swiss francs ($22 million) from existing investors. The funds will enable the company to start Phase I clinical trials with ACI-35 earlier than expected and Pfeifer said the company would be open for a partner to advance it into later-stage trials that are costlier and require more patients. AC Immune has a further vaccine ACI-24 in Phase I/IIa clinical trials to prevent and clear amyloid plaques, another hallmark of the fatal brain-wasting disease. Despite the company having a promising number of drugs in development for the disease, Pfeifer said it was difficult to predict when one could be on the market. "I would say however that in the next three to five years there should be a medication for Alzheimer's out there and hopefully it could be one of ours," she said. Over the past 15 years more than 100 experimental Alzheimer's drugs have failed in tests. Industry analysts believe that the prize for a truly effective drug could be a market worth $10 billion in annual sales. ($1 = 0.9090 Swiss francs) (This version of the story corrects name of vaccine in para 9 to ACI-24 from ACI-35) Claim: Swiss biotech firm starts new Alzheimer vaccine trial.
Example Output:
AC Immune, a privately held biotech company based in Switzerland, has launched the world's first trial of a vaccine against a protein believed to cause Alzheimer's after securing funding from private investors.
