Ex Input:
Why could there be reasonable doubt about the validity of what was stated that she said?, Context: In May 2007, The Daily Telegraph, citing unnamed sources, reported that the Queen was "exasperated and frustrated" by the policies of the British Prime Minister, Tony Blair, that she was concerned the British Armed Forces were overstretched in Iraq and Afghanistan, and that she had raised concerns over rural and countryside issues with Blair. She was, however, said to admire Blair's efforts to achieve peace in Northern Ireland. On 20 March 2008, at the Church of Ireland St Patrick's Cathedral, Armagh, the Queen attended the first Maundy service held outside England and Wales. At the invitation of the Irish President, Mary McAleese, the Queen made the first state visit to the Republic of Ireland by a British monarch in May 2011.

Ex Output:
unnamed sources


Ex Input:
How are the rural medical centers using the highly useful technology of videoconferencing?, Context: Videoconferencing is a highly useful technology for real-time telemedicine and telenursing applications, such as diagnosis, consulting, transmission of medical images, etc... With videoconferencing, patients may contact nurses and physicians in emergency or routine situations; physicians and other paramedical professionals can discuss cases across large distances. Rural areas can use this technology for diagnostic purposes, thus saving lives and making more efficient use of health care money. For example, a rural medical center in Ohio, United States, used videoconferencing to successfully cut the number of transfers of sick infants to a hospital 70 miles (110 km) away. This had previously cost nearly $10,000 per transfer.

Ex Output:
cut the number of transfers of sick infants to a hospital


Ex Input:
what group is mentioned first?, Context: After recovering surprisingly fast from the sack of Rome, the Romans immediately resumed their expansion within Italy. The First Samnite War from 343 BC to 341 BC was relatively short: the Romans beat the Samnites in two battles, but were forced to withdraw before they could pursue the conflict further due to the revolt of several of their Latin allies in the Latin War. Rome beat the Latins in the Battle of Vesuvius and again in the Battle of Trifanum, after which the Latin cities were obliged to submit to Roman rule.

Ex Output:
Romans
