Problem: Tuvalu:

Because of the low elevation, the islands that make up this nation are vulnerable to the effects of tropical cyclones and by the threat of current and future sea level rise. The highest elevation is 4.6 metres (15 ft) above sea level on Niulakita, which gives Tuvalu the second-lowest maximum elevation of any country (after the Maldives). The highest elevations are typically in narrow storm dunes on the ocean side of the islands which are prone to overtopping in tropical cyclones, as occurred with Cyclone Bebe, which was a very early-season storm that passed through the Tuvaluan atolls in October 1972. Cyclone Bebe submerged Funafuti, eliminating 90% of structures on the island. Sources of drinking water were contaminated as a result of the system's storm surge and the flooding of the sources of fresh water.

Where on Tuvalu is the highest elevation?

A: Niulakita

Problem: Richmond emerged a decade after the smoldering rubble of the Civil War to resume its position as an economic powerhouse, with iron front buildings and massive brick factories. Canal traffic peaked in the 1860s and slowly gave way to railroads, allowing Richmond to become a major railroad crossroads, eventually including the site of the world's first triple railroad crossing. Tobacco warehousing and processing continued to play a role, boosted by the world's first cigarette-rolling machine, invented by James Albert Bonsack of Roanoke in 1880/81. Contributing to Richmond's resurgence was the first successful electrically powered trolley system in the United States, the Richmond Union Passenger Railway. Designed by electric power pioneer Frank J. Sprague, the trolley system opened its first line in 1888, and electric streetcar lines rapidly spread to other cities across the country. Sprague's system used an overhead wire and trolley pole to collect current, with electric motors on the car's trucks. In Richmond, the transition from streetcars to buses began in May 1947 and was completed on November 25, 1949.
Who was the inventor of the cigarette-rolling machine?

Answer: James Albert Bonsack

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 680 Ibn al-Zubayr fled Medina for Mecca. Hearing about Husayn's opposition to Yazid I, the people of Kufa sent to Husayn asking him to take over with their support. Al-Husayn sent his cousin Muslim bin Agail to verify if they would rally behind him. When the news reached Yazid I, he sent Ubayd-Allah bin Ziyad, ruler of Basrah, with the instruction to prevent the people of Kufa rallying behind Al-Husayn. Ubayd-Allah bin Ziyad managed to disperse the crowd that gathered around Muslim bin Agail and captured him. Realizing Ubayd-Allah bin Ziyad had been instructed to prevent Husayn from establishing support in Kufa, Muslim bin Agail requested a message to be sent to Husayn to prevent his immigration to Kufa. The request was denied and Ubayd-Allah bin Ziyad killed Muslim bin Agail. While Ibn al-Zubayr would stay in Mecca until his death, Husayn decided to travel on to Kufa with his family, unaware of the lack of support there. Husayn and his family were intercepted by Yazid I's forces led by Amru bin Saad, Shamar bin Thi Al-Joshan, and Hussain bin Tamim, who fought Al-Husayn and his male family members until they were killed. There were 200 people in Husayn's caravan, many of whom were women, including his sisters, wives, daughters and their children. The women and children from Husayn's camp were taken as prisoners of war and led back to Damascus to be presented to Yazid I. They remained imprisoned until public opinion turned against him as word of Husayn's death and his family's capture spread. They were then granted passage back to Medina. The sole adult male survivor from the caravan was Ali ibn Husayn who was with fever too ill to fight when the caravan was attacked.
Who was not able to disperse the crowd that had gathered?
A: unanswerable
