[EX Q]: Verify if the sentiment of the following document towards the entity Chris Caldwell is Neutral . These primes are exceedingly rare and sporadic  said Chris Caldwell  a professor of mathematics and statistics at the University of Tennessee at Martin  who studies prime numbers and has written a history of the Mersenne primes.
"Finding a prime is not going to change any theorems in mathematics  but this is a type of prime that has been interesting to mathematicians since several centuries before Christ "  Caldwell  said. Even the ancient Greek mathematician Euclid talked about what would later become the Mersenne primes  he said.
 Caldwell  added that the discovery was akin to breaking a land speed record.
The last few Mersenne primes have been closer to each other than the researchers expected   he  said.
The numbers seem to occur sporadically because researchers don't fully understand the pattern they follow   he  said. "So you expect in any process that appears random to have some close groupings of numbers. But  we  didn't expect to find another one so soon after the last one."
"In the long run   we  hope to use these data to predict how often these occur "  he  added.

[EX Q]: Verify if the sentiment of the following document towards the entity Heather Nauert is Positive . "We would oppose any violence if that were to take place "  State Department spokeswoman Heather Nauert  said in response to reports that this kind of coordination was being considered. "We hope our voices will be heard in a very strong fashion that we oppose violence on any side of this."
 She  was responding to a report that Iran and Iraq plan to seize control of the border crossings around a semi-autonomous region of northern Iraq that is populated by a Kurdish ethnic minority that plays a crucial role in the U.S.-led coalition to defeat the Islamic State. The tensions have arisen because the Kurds voted in support of breaking away from the rest of Iraq to form their own state  despite opposition from Baghdad and the United States.
 Nauert  took a cautious approach to the diplomatic crisis. "The United States does not want to do anything that would inflame tensions  that's why I'm going to be very cautious with my words "  she  said during Thursday's briefing. "We will continue to offer our assistance to facilitate any dialogue if we are asked."
 Nauert  said  she  had not heard of a request for the United States to close its consulate in northern Iraq.
"Our relationship with the Kurds  in our view  will not change "  she  said.
