Answer:
Chronological order
Step-by-step explanation:
"Mother Teresa" tells the story of Mother Teresa during her years of life, explaining the woman she was and how that made her the icon that is considered today by Catholics around the world. The article is organized in a chronological structure, organizing the events of her life as they happened and making the reader understand her attitudes towards the physical and spiritual maturity that she was building as she got older and as time passed.
In other words, the author may have decided to write the article in chronological order so that the reader would see Mother Teresa's gradual growth and evolution.
