Question: Ruling elders are usually laymen (and laywomen in some denominations) who are elected by the congregation and ordained to serve with the teaching elders, assuming responsibility for nurture and leadership of the congregation. Often, especially in larger congregations, the elders delegate the practicalities of buildings, finance, and temporal ministry to the needy in the congregation to a distinct group of officers (sometimes called deacons, which are ordained in some denominations). This group may variously be known as a "Deacon Board", "Board of Deacons" "Diaconate", or "Deacons' Court". These are sometimes known as "presbyters" to the full congregation.
Try to answer this question if possible: There's a group of officers in the congregation, what other names are they also known by?
Answer: deacons
Question: Tyson Research Center is a 2,000-acre (809 ha) field station located west of St. Louis on the Meramec River. Washington University obtained Tyson as surplus property from the federal government in 1963. It is used by the University as a biological field station and research/education center. In 2010 the Living Learning Center was named one of the first two buildings accredited nationwide as a "living building" under the Living Building Challenge, opened to serve as a biological research station and classroom for summer students.
Try to answer this question if possible: Besides the Living Learning Center what was the other building accredited as a "living building"?

Question: Matrix groups consist of matrices together with matrix multiplication. The general linear group GL(n, R) consists of all invertible n-by-n matrices with real entries. Its subgroups are referred to as matrix groups or linear groups. The dihedral group example mentioned above can be viewed as a (very small) matrix group. Another important matrix group is the special orthogonal group SO(n). It describes all possible rotations in n dimensions. Via Euler angles, rotation matrices are used in computer graphics.
Try to answer this question if possible: What type of angles are made of all invertible n-by-b matrices?
Answer:
unanswerable
