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:.

Ex Output:
Democratic

(CNN) Your "BPA-free" plastic product may be no safer than the product it replaced, says a new UCLA study that analyzed the impact of a common BPA alternative on zebra fish embryos. The study joins a small but growing group of similar research sounding the alarm about so called "BPA-free" alternatives. "Our findings are frightening and important," said senior author and reproductive endocrinologist Nancy Wayne. "Consider it the aquatic version of the canary in the coal mine." After decades of animal research linked BPA (Bisphenol A), a known endocrine disruptor, to problems with brain and reproductive development, early puberty and a rise in breast and prostate cancer, many manufacturers stopped using the chemical to harden plastics, replacing it with "BPA-free" alternatives. The most common replacement is BPS (Bisphenol S), said Wayne.BPA-free alternatives may be no safer than BPA, say researchersMost common alternative, BPS, linked in study to disruptions of estrogen and thyroid hormones 
 Question:In addition to the effect on estrogen, the study also found both _ and BPS affected the thyroid hormone system.

Ex Output:
BPA
