(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

In November 2014, plasma physicist Dr John Brandenburg revealed his theory that an ancient civilisation on Mars was massacred in a nuclear attack. Now, he’s back, and he’s going to be presenting new evidence for his theory at a Nasa-sponsored conference today. He claims there is no other explanation for his proposal that a ‘weapon’s signature’ remains from the attack on Mars. Dr John Brandenburg is to present his theory in Houston, Texas today. He says an ancient Mars civilisation was wiped out by a nuclear bomb. A thin layer of radioactive substances including uranium, thorium (shown in graphic) and radioactive potassium on the surface supposedly provide evidence for this theoryDr John Brandenburg is to present his theory in Houston, Texas todayHe says an ancient Mars civilisation was wiped out by a nuclear bombEvidence for this apparently comes from a 'weapon's signature'And there is apparently no other explanation for his evidenceEarth could also be under threat of attack, claimed Dr Brandenburg 
 Questions:He says that the planet once had _-like temperatures and atmospheric pressures, and was abundant with life and an oxygen-rich atmosphere. (A) John Brandenburg (B) Mars (C) Nasa (D) Houston (E) Texas (F) Earth (G) Brandenburg
