Question: The violent ambush that killed five Dallas police officers and wounded seven more could have been a lot worse, the city's police chief says. Dallas Chief of Police David Brown told CNN Sunday that the slain gunman told police negotiators he wanted to "kill white people, especially white officers." Bomb making materials and a journal were found at Johnson's home during a search Friday. "The material were such that it was large enough to have devastating effects throughout our city and our North Texas area," Brown said. Micah Xavier Johnson, 25, was killed by police in the deadly attack Thursday night during a protest against police killings of African American men. Since the shooting deaths of two black men by white police officers over two days last week, protests have been held across the country. Scores of demonstrators have been arrested, with one flash point being the southern city of Baton Rouge, Louisiana, where DeRay McKesson, one of the most prominent activists linked to the police reform protest movement Black Lives Matter, live streamed his own arrest. Police defended his arrest as a matter of public safety, but demonstrators told U.S. news outlets they believe McKesson was targeted. McKesson was freed on bond Sunday afternoon after being charged with obstructing a highway. "I remain disappointed in the Baton Rouge police, who continue to provoke protesters for peacefully protesting. There's a lot of work to be done, with this police department specifically,'' he said. But Louisiana Governor John Bel Edwards disagreed with McKesson's assessment. The governor told a news conference Sunday that he is proud of the state's law enforcement officers, calling their response to the protests "moderate." In the northern city of St. Paul, Minnesota, where a second man, Philando Castile, was shot to death last week by a policeman after a traffic stop for a broken tail light, hundreds of protesters hurled firecrackers, rocks and bottles at police on Saturday. The heavily armed officers used smoke grenades and... Question: Who is proud of the state's law enforcement officers? Options: A. Philando Castile B. De Ray McKesson C. not enough information D. John Bel Edwards === The correct answer is
Answer: D

Question: The U.S. Supreme Court signaled Wednesday it may be open to new limits on the government's ability to track someone's movements by accessing data on that person's cellphone. A case before the high court could result in a landmark decision in the ongoing debate over civil liberties protections in an era of rapid technological change. At issue is whether law enforcement will be able to access cellphone data that can reveal a person's whereabouts without having to first obtain a court-issued search warrant. The case stems from the conviction of Timothy Carpenter for a series of robberies back in 2010 and 2011. Prosecutors were able to obtain cellphone records that indicated his location over a period of months, information that proved crucial to his conviction. On Wednesday, lawyers for the American Civil Liberties Union argued that law enforcement should be required to obtain a court-ordered search warrant before obtaining such information. They also argued that allowing law enforcement to access the cellphone data without a warrant would violate the prohibition on unreasonable search and seizures contained in the Fourth Amendment to the U.S. Constitution. "It is impossible to go about our daily lives without leaving a trail of digital breadcrumbs that reveal where we have been over time, what we have done, who we spent time with," said ACLU attorney Nathan Freed Wessler, who spoke to reporters outside the Supreme Court following oral arguments. "It is time for the court, we think, to update Fourth Amendment doctrine to provide reasonable protections today." Some of the justices also raised concerns about privacy in the digital age. "Most Americans, I think, still want to avoid Big Brother," Justice Sonia Sotomayor, who often sides with the liberal wing of the court, said. Chief Justice John Roberts, who often sides with conservatives on the court, said the central question was whether the cellphone information should be accessible to the government "without a warrant." Question: Who Justice Sotomayor is in a relation ship with? Options: A. a man B. not enough information C. a woman D. no one === The correct answer is
Answer: B

Question: There is no hiding from the impact agenda. The impact weighting of the Research Excellence Framework has been increased for 2021, and more recently the UK Government announced a new funding stream for knowledge exchange. But achieving impact isn't easy, especially for researchers early in their careers. If you ever have a spare week, or ten, it's worth reading through some of the 6,637 REF impact case studies on the HEFCE website. There are some brilliant and fascinating examples of how researchers have achieved impact, but what strikes me most is how different impact looks across different subjects. At the risk of being flippant, among many of the medical or technological examples there is a familiar pattern and a clear route to impact: make breakthrough; license drug/technology; save lives/millions. For social and political science (not to mention economics, languages, education, philosophy, etc.) the route to impact is much more fragmented. Among the 97 sociology case studies, for example, impact comes from numerous briefings of government officials and parliamentarians, before the academics join "networks" and "committees" discussing their research and wider issues. Their research is covered by national media, they meet even more people practitioners or third sector campaigning organisations to pass on their knowledge. And, after all that, and often a good deal more, sometimes there is a policy or practice change that can be pointed to as a direct impact, sometimes not. Central to much of the impact is "access". Prominent and experienced academics are more likely to get on the committees, know the right journalists and government officials, and have links into third sector organisations, etc. I worked with Professor Sir John Curtice, of election night fame, for a number of years. He didn't need much support. I advised and facilitated, but after 30 years in the game he knew Whitehall (and Holyrood) inside and out and they knew him. But many researchers, especially at the start of their careers, don't... Question: What do researchers need to write about to avoid impact agenda? Options: A. something banal B. something boring C. something groundbreaking D. not enough information === The correct answer is
