Refusing the title of king, Mirwais was called "Prince of Qandahár and General of the national troops" by his Afghan countrymen. He died peacefully in November 1715 from natural causes and was succeeded by his brother Abdul Aziz; the latter was murdered later by Mirwais' son Mahmud. In 1720, Mahmud's Afghan forces crossed the deserts of Sistan and captured Kerman. His plan was to conquer the Persian capital, Isfahan. After defeating the Persian army at the Battle of Gulnabad on March 8, 1722, he proceeded to and besieged Isfahan for 6 months, after which it fell. On October 23, 1722, Sultan Husayn abdicated and acknowledged Mahmud as the new Shah of Persia. The majority of the Persian people, however, rejected the Afghan regime as usurpers from the start. For the next seven years until 1729, the Hotaks were the de facto rulers of most of Persia, and the southern and eastern areas of Afghanistan still remained under their control until 1738. The Hotak dynasty was a troubled and violent one from the very start as internecine conflict made it difficult to establish permanent control. The dynasty lived under great turmoil due to bloody succession feuds that made their hold on power tenuous, and after the massacre of thousands of civilians in Isfahan - including more than three thousand religious scholars, nobles, and members of the Safavid family - the Hotak dynasty was eventually removed from power in Persia. On the other hand, the Afghans had also been suppressed by the Iranian Safavid government represented by its governor Gurgin Khan before their uprising in 1709. 
Question: How did Abdul Aziz die?

Ex Output:
murdered


Ex Input:
Last night, I had a party at my house. Many people were there and most of my friends hung out in both the kitchen and the living room. The living room was fine, but the kitchen was a disaster. I felt the need to clean the floor and in an effort to do so, I took out a mop and mopped up the floor. This took some of the stickiness away and made it feel much better. I sprayed cleaner on the floor before cleaning it and also did some sweeping. This felt good and I was able to clean the floor. After sweeping and mopping the floor, I let it sit for a while so  that I didn't slip on it. It looked shiny and I felt like my house was much cleaner than when my friends came over. Next time, I will follow the same routine when cleaning. 
Question: Who made the mess?

Ex Output:

Their friends
