[Q]: Washington (CNN) While the two vastly disagree on a range of issues -- trade, immigration and climate change, to name a few -- US President Donald Trump and Canadian Prime Minister Justin Trudeau met Monday on rare common ground, a conciliatory gesture forged in large part by Trump's daughter, Ivanka. Trudeau sat across the table from Trump in the Cabinet Room, surrounded by a dozen female CEOs and business leaders. The President pledged the launch of the United States Canada Council for the Advancement of Women Business Leaders-Female Entrepreneurs, intended to discuss, formulate and implement support for women in the workplace.Trump and Trudeau met for the first time MondayIvanka Trump helped lead a meeting focused on women in business

[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 _, 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

[Q]: Warren Gatland’s injury crisis deepened as Wales suffered three casualties in three minutes at Twickenham on Saturday night. Centre Scott Williams, winger Hallam Amos and full-back Liam Williams all left the pitch in the second half and are now major doubts for Thursday’s Pool A meeting with Fiji. With centres Jonathan Davies and Cory Allen already ruled out of the World Cup, the loss of Williams, who taken off on a stretcher in the 63rd minute following a collision with Brad Barritt, will leave the Welsh midfield down to its bare bones for the remaining fixtures. Williams was at the centre of Sam Burgess’s ‘who’s that?’ jibe on Thursday but Gatland could now be forced to go in search of cover for the 24-year-old Scarlets centre.Wales lose three players through injury in Saturday's win over EnglandWarren Gatland given selection headache after latest casualtiesScott Williams, Hallam Amos and Liam Williams all left field injuredREPORT: Wales mount stunning fightback to beat England 28-25
