Input: Consider Input: (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

Output: (B)


Input: Consider Input: (CNN) President Donald Trump is under fire again, this time for his firing of former FBI Director James Comey. But many of his supporters aren't joining the outcry. CNN spoke to Trump backers across the country, and while some of them expressed surprise at Comey's ouster, few said it changed their image of the leader of the free world. Here's what they had to say: Jake Lee, business owner Lee, 46, of West Hollywood, California, said he believes Trump made "the right decision" in axing Comey. "As far as the Comey thing goes, I think he gave him plenty of chances. I think what became the last straw was when he (Comey) made that statement about the classified emails showing up on (Hillary Clinton aide Huma Abedin's and her husband, former Congressman Anthony Weiner's) laptop. You can't have rules for the elitist ruling class and not have those rules apply to everybody else. I think in my opinion that was part of (Trump's) decision. The guy likes to run a tight ship."Many Trump voters across the country say James Comey's firing doesn't change their opinion of the President"I was hoping Trump would've done a lot better with his presidency so far," Kentucky business owner says 
 Questions:He also appreciated the unexpected nature of _'s announcement: "Trump doesn't broadcast what he's gonna do; he just does it, and I like that." (A) Donald Trump (B) FBI (C) James Comey (D) CNN (E) Comey (F) Jake Lee (G) Lee (H) West Hollywood (I) California (J) Hillary Clinton (K) Huma Abedin (L) Anthony Weiner (M) Kentucky
