The 1971 Local Government White Paper proposed abolishing county boroughs, which would have left Plymouth, a town of 250,000 people, being administered from a council based at the smaller Exeter, on the other side of the county. This led to Plymouth lobbying for the creation of a Tamarside county, to include Plymouth, Torpoint, Saltash, and the rural hinterland.

All powers returned when the city become a unitary authority on 1 April 1998 under recommendations of the Banham Commission.
What county did Plymouth unsuccessfully attempt to see created?

Question: His biography of Anthony the Great entitled Life of Antony( , Vita Antonii) became his most widely-read work. Translated into several languages, it played an important role in the spreading of the ascetic ideal in Eastern and Western Christianity. Depicting Anthony as an illiterate and holy man who through his existence in a primordial landscape has an absolute connection to the divine truth, the biography also resembles the life of his biographer Athanasius. It later served as an inspiration to Christian monastics in both the East and the West. The so-called Athanasian Creed dates from well after Athanasius's death and draws upon the phraseology of Augustine's De trinitate.
Is there an answer to this question: Who wrote the autobiography entitled Life of Antony?

Answer: unanswerable

Problem: Digestion:

Digestive systems take many forms. There is a fundamental distinction between internal and external digestion. External digestion developed earlier in evolutionary history, and most fungi still rely on it. In this process, enzymes are secreted into the environment surrounding the organism, where they break down an organic material, and some of the products diffuse back to the organism. Animals have a tube (gastrointestinal tract) in which internal digestion occurs, which is more efficient because more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled.

Why is internal digection better than external?
---
A:
more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled
