Q: Verify if the sentiment of the following document towards the entity John F. Kennedy is Neutral . BOSTON (Reuters) - More than half a century after  U.S. President John F. Kennedy  was struck down by an assassinâs bullet in Dallas  Texas  the United States is due on Thursday to release the final files on the investigation into the killing that rattled a nation.

Academics who have studied  Kennedy âs slaying on Nov. 22  1963  said they expected the final batch of files to offer no major new details on why Lee Harvey Oswald gunned down the first and only Irish-American Roman Catholic to hold the office.
They also feared that the final batch of more than 5 million total pages on the  Kennedy  assassination held in the National Archives will do little to quell long-held conspiracy theories that the 46-year-old presidentâs killing was organized by the Mafia  by Cuba  or a cabal of rogue agents.
Thousands of books  articles  TV shows and films have explored the idea that  Kennedy âs assassination was the result of an elaborate conspiracy. None have produced conclusive proof that Oswald  who was shot dead a day after killing Kennedy  worked with anyone else  though they retain a powerful cultural currency.
âMy students are really skeptical that Oswald was the lone assassin â said Patrick Maney  a professor of history at Boston College. âItâs hard to get our minds around this  that someone like a loner  a loser  could on his own have murdered  Kennedy  and changed the course of world history. But thatâs where the evidence is.â

In 1992  Congress ordered that all records relating to the investigation into  Kennedy âs death should be open to the public  and set a final deadline of Oct. 26  2017 for the entire set to be made public.
 Kennedy âs assassination was the first in a string of politically motivated killings  including those of  his  brother Robert F. Kennedy and civil rights leader Martin Luther King Jr.  that stunned the United States during the turbulent 1960s.  He  remains one of the most admired U.S. presidents.

Q: Verify if the sentiment of the following document towards the entity Terrell Washington is Negative . Terrell  Washington   37  was charged with attempted first-degree murder and aggravated battery with a firearm after the victim identified him as her shooter  according to court records.
On Jan. 18   Washington  came over to the victimâs apartment in the 4000 block of West Gladys Avenue about 9:15 p.m.
They were talking and smoking cigarettes  and  Washington  became âincreasingly angryâ and repeatedly told the woman to lower her voice  according to Assistant Stateâs Attorney Julia Ramirez.
The woman became frustrated and told  Washington  to leave her apartment. He pulled a handgun from his waistband and shot her in the arm and leg  prosecutors said.
 Washington  then ran from the apartment through the front door  leaving it open  Ramirez said.
The victim was taken to the hospital and was treated for gunshot wounds. She later identified  Washington  as the person who shot her.
 Washington   of the 5300 block of West Adams  was arrested Friday. He was ordered held without bail during a Sunday court hearing before Judge Mary Marubio.

Q: Verify if the sentiment of the following document towards the entity Alexander Kellner is Neutral . Scientists found hundreds of pterosaur bones at the surface of the site (Alexander Kellner  Museu Nacional/UFRJ).
âThis is by far the most exciting discovery that I know of â said  Alexander Kellner   co-author of the new study and paleontologist at the National Museum of the Federal University of Rio de Janeiro in Brazil.
And  Kellner  isnât some newbie to pterosaur discoveries.  He âs been studying these ancient animals for more than 30 years and has personally been a part of naming or describing more than 20 species. This includes the species in question  Hamipterus tianshanensis  which  Kellner   Wang  and a team of their colleagues discovered in 2014.
With a wingspan of approximately 11 feet  an adult H. tianshanensis may have been something like an albatross. You know  if albatrosses had large crests running the lengths of their heads and spikelike teeth. This species does not appear to have had feathers   Kellner  said.
Probably a fish-eater  H. tianshanensis inhabited hot and dry environments but would have buried its eggs in the sand and vegetation found on the shores of lakes or rivers. This is also likely why so many eggs have been found together.  Kellner  suspects recent storms caused torrential flooding which unearthed the eggs and washed them into the fossil record  along with other  older pterosaurs that fell victim to the deluge.
The paper says that H. tianshanensis hatchlings wouldnât have been able to fly immediately because several of the eggs the team examined showed wing bones that were less developed than expected. This may have meant that baby pterosaurs would have spent some time on the ground hunting insects and generally trying not to be eaten before learning how to take wing.  Kellner  even speculated that the pterosaur females and maybe even males would have stuck around to feed the hatchlings to help get them through such a precarious stage.
Pterosaurs ran the gamut from the gigantic  aircraftlike Quetzalcoatlus all the way down to animals about the size of a sparrow  such as Nemicolopterus. Some had the long  pointy snouts we typically associate with the flying reptiles. Others boasted wild and crazy crests  which may have been used to attract the opposite sex  as has been suggested with H. tianshanensis. And still other pterosaur species had short  squat skulls more like  that of a frog   Chiappe said. (Albeit  a very scary frog.)
Pterosaurs were the very first animals with backbones to master powered flight   Kellner  said. How they did what they did  and did it for as long as they did  is just one of the mysteries he and his colleagues hope to solve.
