The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsidssometimes referred to as mammal-like reptilesbefore giving rise to the proto-mammals (Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of the non-avian dinosaurs 66 million years ago.

FBI Directors are appointed by the President of the United States. They must be confirmed by the United States Senate and serve a term of office of five years, with a maximum of ten years, if reappointed, unless they resign or are fired by the President before their term ends. J. Edgar Hoover, appointed by Calvin Coolidge in 1924, was by far the longest-serving director, serving until his death in 1972. In 1968, Congress passed legislation as part of the Omnibus Crime Control and Safe Streets Act Pub.L. 90351, June 19, 1968, 82 Stat. 197 that specified a 10-year limit, a maximum of two 5-year terms, for future FBI Directors, as well as requiring Senate confirmation of appointees. As the incumbent, this legislation did not apply to Hoover, only to his successors. The current FBI Director is James B. Comey, who was appointed in 2013 by Barack Obama.
Who is the current FBI director?

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.
The congregation consists of laymen elected by who?
A:
unanswerable
