PROBLEM: (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 _, but Mars 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

PROBLEM: (CNN) France's defeated political establishment has begun to rally against far-right leader Marine Le Pen as she goes head-to-head against political novice Emmanuel Macron in the final race for the French presidency. As Le Pen continued to celebrate the highest-ever voting tally for her National Front party, French President François Hollande joined candidates knocked out in the first round in endorsing Macron, who ended his insurgent campaign with a result that confounded expectations. Macron, a pro-European centrist, took first place with 24.01% of the first round voting, while the anti-immigrant, anti-EU Le Pen came second on 21.30%, according to final results released Monday by the French Interior Ministry.Le Pen taking leave of absence as National Front leaderFrench President Hollande says he will vote for Macron

PROBLEM: Washington (CNN) When King Abdullah II of Jordan was presented with a wave of refugees from Syria, he welcomed more than a million people into his country. When President Donald Trump was presented the same, he closed the door. The two world leaders who met Wednesday are united in the fight against ISIS -- a fact Trump heralded during a news conference in the White House Rose Garden -- but the duo are each other's antithesis when it comes to responding to the now ever-present issue of Syrian refugees. The meeting comes as the focus on Syria's ongoing civil war is at its brightest: The White House, along with activist groups and other foreign leaders, blamed forces tied to Syrian President Bashar al-Assad on Tuesday for a chemical attack in a rebel-controlled area of Syria.Trump has sought to slow refugees coming to the USAbdullah has welcomed many refugees to Jordan
