According to Michener, DeLamater and Myers, a symbol is an arbitrary form that is used to refer to ideas, feelings, intentions or any other subject. It is arbitrary because there is nothing intrinsic in the symbol that inevitably links it to the subject it symbolizes.

The answer is B. Literacy rates are increasing in the region, and the gap between men and women is decreasing. Annual regional-level literacy estimates based on national data and the Unesco Institute for Statistics projections from 1990 to 2016 tell us that Eastern and South-Eastern Asia, Southern Asia, and Northern Africa and Western Asia have made the greatest progress in improving adult literacy over the past 26 years .
According to the Fact Sheet No. 45 dated September 2017 of the Unesco Institute for Statistics, Northern Africa and Western Asia literacy rate went from 64% to 81. The youth literacy rate increased in Northern Africa and Western Asia from 80% to 90% and sub-Saharan Africa from 65% to 75%. Female literacy rates-lower than male literacy rates at the start of the period - generally grew faster than male literacy rates between 1990 and 2016.Thus, the gap between men and women has decreased in all regions over the past 26 years.
