Question: Researchers have discovered four extinct underwater volcanoes thousands of feet below the water off the coast of Sydney The calderas are believed to have formed 50 million years ago when supercontinent Gondwana was splitting up into the regions we now know as Australia and New Zealand. And this quartet of 'hotheads' may offer geologists clues about how exactly this tectonic movement took place. The volcanoes were discovered 125 miles (200km) off the southwestern Australian coast using the Investigator ocean explorer from the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Scientists from the University of New South Wales Australia were searching for nursery grounds for larval lobsters when the sonar images spotted the volcanoes 16,100 feet (4,900 metres) underwater.Four volcanoes found in a cluster 125 miles (200km) off coast of SydneyResearchers found the ancient underwater formation by accidentCluster is 12 miles (20km) long, 4 miles (6km wide) and rises 230ft (700m)Experts believe they tell 'part of the story' of how Australia and New Zealand separated between 40 and 80 million years ago 
 Questions:'The ship is constantly mapping the sea floor as it travels, opening up a previously undiscovered and unknown world,' explained _. (A) Sydney (B) Gondwana (C) Australia (D) New Zealand (E) Australian (F) Commonwealth Scientific and Industrial Research Organisation (G) University of New South Wales (H) Four (I) Cluster

Answer: (F)


Question: Washington (CNN) President-elect Donald Trump appeared open Friday to compromising on his oft-repeated pledge to repeal and replace Obamacare -- citing a conversation with none other than President Barack Obama himself. But the openness was complicated by a shift in the official positions listed on his website. The comments, made in an interview with the Wall Street Journal, signal less of a policy shift for Trump than a change from the rhetoric that helped win him the presidency just three days ago and could set up a fight with conservatives. Trump told the paper he was reconsidering his stance after Thursday's meeting with Obama, who urged him to protect parts of the law. Trump said he would like to keep the provision forbidding discrimination based on pre-existing conditions and to allow young Americans to remain on their parents' healthcare plans.Trump told the paper he was reconsidering his stance after Thursday's meeting with ObamaIt's a far cry from what Trump uttered during the primary to his boisterous fans at rallies 
 Questions:Trump's positions on Friday are not entirely new, as he's previously voiced support for certain parts of _ as a candidate. (A) Washington (B) CNN (C) Donald Trump (D) Obamacare (E) Barack Obama (F) Wall Street Journal (G) Trump (H) Americans

Question: It is a mystery that has baffled the world's top scientists - why are there 'blood streaks' on one of Saturn's moons? 'It's clearly painted on the surface in some way that we do not as yet understand,' says Paul Schenk of the Lunar and Planetary Institute, who presented the results of the latest investigation at the American Geophysical Union's annual meeting. 'We basically have a little mystery.' Cassini first spotted these mysterious red lines, which stretch 1,000 of miles across, scratched across the surface of Saturn's icy moon Tethys. The unexplained arc-shaped 'blood trails' are among the most unusual colour features on Saturn's moons to be revealed by the probe.The Cassini probe spotted mysterious red lines on Tethys, several hundred miles long and only a few miles wideScientists thought they may be the result of some type of deformation on the moon caused by a strange orbitBut simulations ruled out this possibility, and now astronomers say fractures unseen by Cassini may be the cause 
 Questions:This may be because its proximity to Saturn causes more tidal warming, and that warming kept _ partially molten longer. (A) Saturn (B) Paul Schenk (C) Lunar and Planetary Institute (D) American Geophysical Union (E) Cassini (F) Tethys
