Q: Passage: In Texas, English is the state's de facto official language (though it lacks de jure status) and is used in government. However, the continual influx of Spanish-speaking immigrants increased the import of Spanish in Texas. Texas's counties bordering Mexico are mostly Hispanic, and consequently, Spanish is commonly spoken in the region. The Government of Texas, through Section 2054.116 of the Government Code, mandates that state agencies provide information on their websites in Spanish to assist residents who have limited English proficiency.
