Sent 2: GOP leaders submitted the new offer Tuesday afternoon in an effort to appease Democrats, whose votes are needed to avert a shutdown of federal agencies, several House and Senate aides said.
Sent 3: However, Republicans also insisted on increases in border security and defense spending, including money to repair existing fencing and new surveillance technology to patrol the nearly 2,000-mile border.

Problem: Paragraph- Sent 1: MADRID, Spain (CNN) -- Relatives of a woman killed in a Spanish airline crash were erroneously given the remains of another victim, and then were asked by authorities to return them, CNN partner network CNN+ reported Thursday.
Sent 2: The victims of the crash were first laid out at a Madria convention center.
Sent 3: A Madrid judge has opened an investigation into the error, and judicial sources say the initial indication is that the mixup occurred not in the proper identification of the victim, but in delivering the wrong remains to the family in question, CNN+ reported.
Sent 4: The family Wednesday received an urn numbered 104, and were told it contained the ashes of their loved one, Pilar Gonzalez Ferreira, who died in the crash.
Sent 5: But as the family was preparing to leave Madrid, officials called to tell them about the error and asked for the return of urn 104, CNN+ reported.
Sent 6: Instead of urn 104, the family was supposed to have received urn 134, which actually contains the remains of Pilar Gonzalez, CNN+ reported, citing judicial sources and another family which also lost a relative in the crash.
