[Q]: Information: - New Edition is an American boy band from Roxbury, a neighborhood in Boston, Massachusetts, formed in 1978. The group reached its height of popularity during the 1980s. They were the progenitors of the boy band movement of the 1980s and 1990s and led the way for groups like New Kids on the Block (also formed in the Boston area), The Boys, Boyz II Men, Hi-Five, Backstreet Boys, and NSYNC. The group recorded mostly as a quintet. - Ralph Edward Tresvant Jr. (born May 16, 1968), also known as Rizz or Rizzo, is an American contemporary R&B singer best known as one of the lead singers of R&B/pop group New Edition. As a solo artist, Tresvant released the album "Ralph Tresvant" (1990). In 2008, he began touring with Bobby Brown and Johnny Gill in a new group named Heads of State. - '' One More Day '' was the final single from the Home Again album . It was released in the US with a B - side featuring a Darkchild remix to '' Something About You '' . Ricky Bell and Ralph Tresvant were the lead vocalists . All six members were featured as background vocalists . - Johnny Gill Jr. (born May 22, 1966), also known as J.G. or J. Skillz, is an American singer-songwriter and actor. Gill is the sixth and final member of the R&B/pop group New Edition, and was also a member of the supergroup called LSG; with Gerald Levert and Keith Sweat. He is currently in the new group Heads of State with New Edition members Bobby Brown and Ralph Tresvant touring. - Robert Barisford "Bobby" Brown (born February 5, 1969) is an American singer, songwriter, rapper, dancer and actor. Brown started his career as one of the frontmen of the R&B and pop group New Edition, from its inception in 1978 until his forced exit from the group in 1985 following a period of misbehavior and rebellious behavior on his part. Starting a solo career, he became a hit success with his second album in 1988, "Don't Be Cruel", which spawned a number of hit singles including the self-penned "My Prerogative", and the Grammy Award-winning "Every Little Step" which became his signature hit. Brown had a string of top ten hits on various "Billboard" charts between 1986 and 1993. Brown is noted as a pioneer of new jack swing, a fusion of R&B. He returned to the group for a reunion album and tour from 1996-1997, and has returned with all six members for another stint since 2005. What is the relationship between 'one more day ' and 'new edition'?

Problem: Information: - Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics. - Geometry (from the ; "geo-" "earth", "-metron" "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. - In geometry , the ( angular ) defect ( or deficit or deficiency ) means the failure of some angles to add up to the expected amount of 360 or 180 , when such angles in the plane would . The opposite notion is the excess . Classically the defect arises in two ways : the defect of a vertex of a polyhedron ; the defect of a hyperbolic triangle ; and the excess also arises in two ways : the excess of a toroidal polyhedron . the excess of a spherical triangle ; In the plane , angles about a point add up to 360 , while interior angles in a triangle add up to 180 ( equivalently , exterior angles add up to 360 ) . However , on a convex polyhedron the angles at a vertex on average add up to less than 360 , on a spherical triangle the interior angles always add up to more than 180 ( the exterior angles add up to less than 360 ) , and the angles in a hyperbolic triangle always add up to less than 180 ( the exterior angles add up to more than 360 ) . In modern terms , the defect at a vertex or over a triangle ( with a minus ) is precisely the curvature at that point or the total ( integrated ) over the triangle , as established by the Gauss -- Bonnet theorem . - Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. What is the relationship between 'angular defect' and 'quantity'?
