Suppose The Taj Mahal is an ivory-white marble mausoleum on the right bank of the Yamuna river in the Indian city of Agra. It was commissioned in 1631 by the Mughal emperor, Shah Jahan, to house the tomb of his favourite wife, Mumtaz Mahal. The Taj Mahal is regarded by many as the finest example of Mughal architecture, a style that combines elements from Persian, Indian, and Islamic architectural styles.
Can we infer that "The Taj Mahal was built in memory of Shah Jahan's first wife."? Yes, no, or maybe?
