Question: Chindia is a portmanteau word that refers to China and India together in general, together, they contain over one-third of the total number of humans currently living, and is called?

<P0-S0> In demographics, the world population is the total number of humans currently living. <P0-S1>  The world population was estimated to have reached 7.5 billion in April 2017 . <P0-S2>  The United Nations estimates it will further increase to 11.2 billion by the year 2100. <SEP> <P1-S0> In human genetics, the Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. <P1-S1>  The term Y-MRCA reflects the fact that the Y chromosomes of all currently living males are directly derived from the Y chromosome of this remote ancestor. <P1-S2>  The analogous concept of the matrilineal most recent common ancestor is known as "Mitochondrial Eve" (mt-MRCA, named for the matrilineal transmission of mtDNA), the most recent woman from whom all living humans are descended matrilineally. <P1-S3>  As with "Mitochondrial Eve", the title of "Y-chromosomal Adam" is not permanently fixed to a single individual, but can advance over the course of human history as paternal lineages become extinct. <SEP> <P2-S0> Chindia is a portmanteau word that refers to China and India together in general. <P2-S1>  The credit of coining the now popular term goes to Indian Member of Parliament Jairam Ramesh. <P2-S2>  China and India share long borders, are both regarded as growing countries and are both among the fastest growing major economies in the world. <P2-S3>  Together, they contain over one-third of the world's population (nearly 2.7 billion). <P2-S4>  They have been named as countries with the highest potential for growth in the next 50 years in a BRIC report. <P2-S5>  BRIC is a grouping acronym that refers to the countries of Brazil, Russia, India and China. <SEP> <P3-S0>  This is the sacred sign of the invisible sacrifice. <P3-S1>  Divine Wisdom provides for each thing according to its mode. <P3-S2>  Therefore, it is proper that the remedy have a corporeal side, leading to the spiritual. <P3-S3>  A sign is the way one obtains knowledge of something else. <P3-S4>  St. Augustine says (Tract. <P3-S5>  Dei x): The visible sacrifice is the sacrament. <P3-S6>  The power of the sacraments is from God, alone. <P3-S7>  A sacrament is a sign. <P3-S8>  It can be found through his writings in the "Summa contra Gentiles" and in the "Summa Theologiæ". <P3-S9>  Augustine (commenting on John 1,33): "He upon Whom you shall see the Spirit, ...that John did not know that our Lord, having the authority of baptizing, would keep it to Himself, but that the ministry would certainly pass to both good and evil men...What is a bad minister to you, wherever the Lord is good?" <P3-S10>  As can be seen, Aquinas relied heavily on Scriptural passages, as well as the writings of various Church Fathers. <P3-S11>  Moreover, it is a sacred sign. <P3-S12>  There are three reasons sacraments are necessary to the salvation of humans: First, it is in the nature of humans to be led by things corporal and sensible to things that are spiritual and intelligible. <P3-S13>  Augustine (Contra Faust xix): "It is impossible to keep men together in one religious denomination, whether true or false, except they be united by means of visible signs or sacraments." <P3-S14>  Wisdom 7,1 : "she... ordered all things sweetly"; and from Matthew 25,15: "[she] gave to everyone according to his proper ability."
