Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_3211 ( "Region" text, "HDI" text, "Life expectancy at birth (2001-2002)" text, "Adult literacy rate (2009)" text, "Combined gross enrollment ratio (2009)" text, "GDP (PPP) per capita (2008)" real )

### Question ###
What is the gdp per capita in 2008 for the region that had a combined gross enrollment ration of 89.0?

### Accurate SQL ###

SELECT MIN("GDP (PPP) per capita (2008)") FROM table_3211 WHERE "Combined gross enrollment ratio (2009)" = '89.0'
