question:
Washington (CNN) As the Senate prepares to vote this week on Neil Gorsuch's nomination, it's unclear yet whether Republicans will have enough votes to end an expected Democratic filibuster. Republicans, who have a 52-48 majority, need a total of eight Democrats to get to 60 -- the critical number required to end the filibuster. If they don't reach 60, they can still get around that filibuster, but it would require taking a highly controversial step to change the Senate rules, a move also known as the nuclear option. RELATED: Here's where Republicans stand on the nuclear option Republicans already have three Democrats who will vote with them to end the filibuster, so they need five more of the remaining eight undecided Democrats -- as of Sunday -- to do the same and reach that 60 number.Republicans need at least give more Democrats to help them confirm Neil Gorsuch under current rulesThe GOP has three Dems, but they've only got nine undecideds left to choose from as of Sunday 
 Question:Here's a look at the nine undecided _ and what they've said recently about Gorsuch:.

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
