[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 Mariano Rajoy is Neutral . More than half the seats in Catalonia ' s 135 - seat parliament will be occupied by pro - independence parties .  Spanish Prime Minister Mariano Rajoy ' s own right - wing People ' s Party alone looks to lose 60 % of their seats  . But there ' s one person who most certainly won ' t be sitting in one of those seats   even though — thanks to a YouTube video that ’  s  been viewed almost a million times —  he  most likely did more than a little to help Thursday ' s overwhelming pro - independence win . “ The situation on Oct . 1 changed everything  ” Albano Dante Fachin told BuzzFeed News as  he  cleaned out  his  office inside Catalonia ’ s parliament building on Thursday night . Oct . 1 was the day Catalonia held a referendum on whether to separate from Spain   a move the Spanish government had tried desperately to prevent . Police and other armed forces were sent into the region to try to keep people from the polls   but Catalan leaders still declared a victory for the independence movement . After the vote   the Spanish senate triggered Article 155 of the country ’ s constitution   which stripped the region of its autonomy . Thursday night ’ s snap election was called by Rajoy after he used his new authority to dissolve the Catalan parliament and imprison eight politicians . Catalan President Carles Puigdemont fled to Brussels   where he has been campaigning via livestream and social media . It ’ s been a hectic election full of vicious identity politics   disorienting misinformation   and increasing paranoia among Catalans about Spanish governmental overreach . Seven major parties were vying for seats on Thursday . But for most voters   instead of thinking of things in terms of right and left   it was a decision between a pro - Catalan independence voting bloc and a rival bloc of parties that have campaigned on Catalonia remaining a part of Spain . For Catalans   it came down to a race between the left - wing progressive party Esquerra Republicana on the “ independentista ” side and economic liberal party Ciudadanos on the unionist   a victory for either deciding the region ’ s future relationship with Madrid . There was one party   though   that tried to stay out of the independence debate . Podemos   a left - wing anti - corruption party that was founded in 2014 out of Spain ’ s Occupy Wall Street equivalent   resisted choosing a side . But thanks to Fachin   its now - former general secretary   it ended up having one of the biggest impacts on this week ’ s vote . Fachin shocked Catalans last week after he announced via YouTube video that he was resigning from Podemos and voting for a pro - independence party . The video has currently been watched over 800   000 times and   according to Spanish media   it ’ s the most watched video of the election . His decision to vote for an independence party to protest Spain ’ s crackdown on the region   and not because he agreed with the results of the Catalan referendum   became a lightning rod on social media .
