[Q]: (CNN) European Union and Turkish officials reached an agreement Friday on how to deal with a flood of Syrian refugees. "(The) agreement isn't a silver bullet, but part of EU's comprehensive strategy on migration," European Council President Donald Tusk tweeted Friday. The deal came after talks involving Turkish Prime Minister Ahmet Davutoglu, Tusk and a handful of other key European officials. The final language was then put up for a vote before representatives from the 28 European Union member states, who approved it unanimously, according to the European Council president. The talks were held to address the largest influx of refugees into Europe since World War II, though the more than 1 million people who have fled to there pale compared to the more than 2.7 million registered in Turkey alone.

[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 
 Questions:Earth is the only analog we have for Mars, but _ obviously behaves differently, the researchers said. (A) CNN (B) Mars (C) RSL (D) Nature Geoscience (E) US Geological Survey (F) Planetary Science Institute (G) University of Arizona (H) Durham University (I) England
