Take the following as truth: From Humayun's death came the splendid monument located in Nizamuddin, the Tomb of Humayun, which was built by his widow Haji Begum and the inspiration for the Taj Mahal.
Then the following statement: "Haji Begum was devastated by her husband's death and spent every day at his tomb after its construction." is true, false, or inconclusive?
