Example Input: Riverside, California (CNN) As she has trudged toward the Democratic nomination, Hillary Clinton has struggled to find a message that could impassion her Democratic voters the way her rival Bernie Sanders has.

In speech after speech across the Golden State, Clinton delivered a fiery, point-by-point takedown of the real estate magnate, casting him as a greedy bully who was eager to profit from the financial woes of the middle class Americans who lost homes and jobs in the 2008 economic crash.Clinton has amped up her attacks against Trump while campaigning in California this week"The fact is Donald Trump thought he could make money off of people's misery," she said

Example 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
Example Output: (B)
