[Q]: (CNN) Since the discovery of dark streaks on the slopes of Mars in 2011, astronomers have been excited about potential evidence of water beneath the surface of the red planet. If there are subsurface water flows on Mars, they could allow life -- even on a microbial level -- to exist as well. But further study of these recurring slope lineae, known as RSL, is revealing something else. Those dark streaks may be the result of granular flows like sand and dust, according to a study published Monday in the journal Nature Geoscience. The study is the product of a research team made up of representatives from the US Geological Survey, the Planetary Science Institute, the University of Arizona and Durham University in England.The flows correlate more with sand on active dunes rather than subsurface waterResearchers studied flows at 10 sites

[Q]: Nasa scientists say they have fixed a glitch that saw them lose contact with the New Horizon’s space probe just days before its close encounter with Pluto - and have released a new image of four unknown 'black spots' on the dwarf planet. The spacecraft entered ‘safe mode’, cutting contact with the Earth over the weekend, due to a timing flaw as it performed operations ahead of its fly past Pluto next week. Scientists leading the mission say they hope to return the space probe to full operation by Tuesday and the mission to fly within 7,750 miles (12,500km) of Pluto on July 14 will go ahead as planned.Nasa lost touch with the space probe for 89 minutes on Saturday 4 JulyNew Horizons' autopilot put spacecraft's main computer into 'safe mode'Scientists leading the mission hope to have it fully operation by 7 JulyNew Horizons is due to be the first spacecraft to fly past Pluto on July 14 
 Questions:The three images together show the full extent of a continuous swath of dark terrain that wraps around much of _’s equatorial region. (A) Nasa (B) New Horizon (C) Pluto (D) New Horizons
[A]: (C)


[Q]: (CNN) A police officer accidentally shot and killed a retired Minnesota mother of two during a civilian police drill in Punta Gorda, Florida, that was supposed to employ only blank ammunition, police said. The officer, identified as Lee Coel, shot Mary Knowlton on Tuesday night during a "shoot/don't shoot" role-play scenario in which officers make decisions on using simulated lethal force, Punta Gorda Police Chief Tom Lewis said at a news conference. The retired librarian was playing an officer in the scenario, which was held just outside the police complex, officials said. Coel was playing the role of a "bad guy" when he opened fire as nearly three dozen people looked on.Lee Coel, officer who accidentally killed woman, joined force in 2014Police chief: Gun used in a demonstration accidentally had a live round in it 
 Questions:_ was transported to a local hospital where she was pronounced dead. (A) Minnesota (B) Punta Gorda (C) Florida (D) Lee Coel (E) Mary Knowlton (F) Tom Lewis (G) Coel
