The statements that accurately describe Teresa of Avila are:
- She organized a group of nuns called the Discalced Carmelites.
- She founded more than a dozen new convents where nuns were devoted to prayer.
- She was a Spanish nun who inspired many Spaniards.
The other statements regarding her execution for heresy in 1622 and her encouragement of nuns to preach among the poor are not accurate. Teresa of Avila was not executed, and she primarily focused on a life of contemplation rather than public preaching.
