Problem: Text: A 2012 study by The Pew Charitable Trusts estimates that 24% of the voting-eligible population in the United States are not registered to vote, a percentage that represents ''at least 51 million eligible U.S. citizens.'' Numerous states had a history of creating barriers to voter registration through a variety of fees, literacy or comprehension tests, and record-keeping requirements that in practice discriminated against racial or ethnic minorities, language minorities, and other groups. The Voting Rights Act of 1965 forbade such abuses and authorized federal oversight in jurisdictions of historic under-representation of certain groups. States continue to develop new practices that may discriminate against certain populations. By August 2016, federal rulings in five cases have overturned all or parts of voter registration or voter ID laws in Ohio, Texas, North Carolina, Wisconsin, and North Dakota that were found to place undue burden on minorities and other groups among voters. The states are required to offer alternatives for the November 2016 elections; many of these cases are expected to reach the US Supreme Court for additional hearings.

Question: is there a fee to register to vote?
A: no

Problem: Text: According to the Vienna Convention on the Law of Treaties, a state that has signed but not ratified a treaty is obliged to refrain from ''acts which would defeat the object and purpose'' of the treaty. However, these obligations do not continue if the state has ''made its intention clear not to become a party to the treaty''. Four signatory states (Israel, Russia, Sudan, and the United States) have informed the UN Secretary General that they no longer intend to become parties to the Rome Statute, and as such have no legal obligations arising from their signature.

Question: is the us party to the rome statute?
A: no

Question: can a violin play two notes at once?
