[EX Q]: Verify if the sentiment of the following document towards the entity Dante de Kort is Positive . Last winter   Dante de Kort -- an eight-year-old boy who lives in central Arizona --  found a dead collared peccary  a wild pig-like animal  near  his  house.  He  set up a motion-controlled camera nearby  and over the next ten days  was surprised to discover footage of the peccary's herd returning to visit their dead herd-member  over and over.
When  he  wrote up  his  findings in a school science-fair presentation  it caught the attention of local biologist Mariana Altricher. It looked like the wild pecarries were in mourning  which was surprising: Scientists have seen grief-like behavior in animals like elephants  dolphins and primates  which are known for their high level of intelligence. But never in these creatures  as National Geographic reports:
Having studied the social  pig-like mammals for years  Altrichter knew how tightly bonded peccaries could be. But she'd never witnessed herd members return to a body repeatedly ... “It was pretty amazing because it wasn’t just an immediate reaction and then they moved on—it went on for 10 days ” says Altrichter  chair of the International Union for Conservation of Nature’s Peccary Specialist Group. [snip] In the videos  the peccaries pay close attention to the body  nuzzling  biting  sniffing  and staring at it. They slept next to the carcass  and even tried to lift it by wedging their snouts under the body and pushing upward. And when a pack of coyotes approached their fallen peer  the herd chased them away. “It really surprised me that they would stand up to the coyotes ” says  de Kort   noting the peccaries were outnumbered.
Altricher used the video evidence to write a scientific paper -- "Collared peccary (Pecari tajacu) behavioral reactions toward a dead member of the herd" -- that lists  de Kort  as its lead author.

[EX Q]: Verify if the sentiment of the following document towards the entity Mitt Romney is Neutral . With Orrin Hatch (finally) retiring  the recruitment efforts to get  Mitt Romney  to run for that seat started immediately. With the revelation that  Romney  received treatment for prostate cancer over the summer  it may not be a slam dunk he runs  but if he does  Donald Trump shouldnât expect  Mitt  to just get in line.
That was evident when  Mitt  tweeted the following this morning:
The poverty of an aspiring immigrantâs nation of origin is as irrelevant as their race. The sentiment attributed to POTUS is inconsistent w/ Americaâs history and antithetical to American values. May our memory of Dr. King buoy our hope for unity  greatness  & âcharity for all.â  â Mitt Romney (@MittRomney)  January 15  2018
 Romney  pushed back pretty hard here. It will be interesting to see how Trump reacts because everybody knows  he âs fuming. Trump supporters  meanwhile  continue to pivot with whatever Trump says. At first  the White House didnât deny  he  made the comments and fans went with  âHey   he âs right!â When  he  denied making the statements  they pivoted to âHey  fake news!â

[EX Q]: Verify if the sentiment of the following document towards the entity Akbar Hashemi Rafsanjani is Positive . Opposition sympathiser and powerful cleric Akbar Hashemi Rafsanjani has ratcheted up the pressure on the Iranian regime ahead of the first anniversary of the disputed presidential election.
 The reappearance of Rafsanjani's comments comes just days before the June 12 anniversary of the presidential poll that returned Mahmoud Ahmadinejad to power and sparked one of the worst internal crises in the Islamic republic's history.
 Iran was rocked by widespread and deadly street unrest immediately after Ahmadinejad's re-election -- a result his opponents said had been rigged.
 Now Rafsanjani's website has again reproduced the text of his year-old letter to Khamenei in which he warned of social upheaval if the leader remained silent about a remark Ahmadinejad made before the election.
 In a television debate just days before the poll  Ahmadinejad accused Rafsanjani's family of corruption  prompting the cleric to send his letter of complaint to the supreme leader.
 Addressing Khamenei in such a manner is unheard of in Iran where the supreme leader is the ultimate authority and has the final say on all strategic issues.
 The Rafsanjani website also repeated remarks he made during a Friday prayer sermon last July 17 as the post-election unrest raged  when he openly said the election result had broken the trust of Iranians.
 "What should we do?" Rafsanjani asked rhetorically in the sermon. "Our key issue is to return the trust which the people had and now to some extent is broken.
 "It is not necessary that in this situation people be jailed. Let them join their families. We should not allow enemies to rebuke and ridicule us because of detentions. We should tolerate each other " he said.
 Rafsanjani is a sympathiser of the opposition  especially Mir Hossein Mousavi who was runner-up in the presidential election.
 Meanwhile Rafsanjani's daughter Faezeh  who heads an Islamic federation of female sports  issued a statement denouncing an "attack against her office overnight Friday " the opposition Rahesabz.net website reported.
