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)

Example Input: Washington (CNN) A stunning report by The Washington Post Monday said President Donald Trump revealed highly classified information to the Russian foreign minister and ambassador during last week's meeting at the White House.

National security adviser H.R. McMaster said in a statement provided by White House press secretary Sean Spicer following the disclosure that Trump and the officials, Russian Foreign Minister Sergey Lavrov and Russian Ambassador to the US Sergey Kislyak, discussed "common threats."A published report cited officials who said Trump shared highly classified information with Russians last weekHe has repeatedly blasted others for sharing classified information

Example Input: (CNN) -- Heavy rains from the outer bands of Typhoon Saola, which hovered near the Philippines beginning last week, have left 23 people dead and another five injured, an official with the National Disaster Coordinating Center said Thursday. The center's executive director, Benito Ramos, told CNN in a telephone interview that another 129 people -- most of them fishermen -- had been rescued. Forty-four evacuation centers were opened as Manila and the cities of Valenzuela and Malabon north of the capital along Manila Bay remained flooded, he said. In all, Saola dropped as much as half a meter (1.5 feet) of rain over the Philippines, said CNNI Meteorologist Taylor Ward.129 people, most of them fishermen, have been rescued in the Philippines44 evacuation centers are openThe typhoon has moved on to TaiwanIt is expected to continue on to China 
 Questions:Rains over the Philippines were only intermittent by Thursday at about 4 a.m., when the typhoon -- packing winds of 157 kph (98 mph) was making landfall in northeast _, said Ward.
