Problem: Carnival:

La Diablada Carnival takes place in Oruro in central Bolivia. It is celebrated in honor of the miners' patron saint, Virgen de Socavon (the Virgin of the Tunnels). Over 50 parade groups dance, sing and play music over a five kilometre-long course. Participants dress up as demons, devils, angels, Incas and Spanish conquistadors. Dances include caporales and tinkus. The parade runs from morning until late at night, 18 hours a day, 3 days before Ash Wednesday. It was declared the 2001 "Masterpieces of Oral Heritage and Intangible Heritage of Humanity" for UNESCO. Throughout the country celebrations are held involving traditional rhythms and water parties. In Santa Cruz de la Sierra, on the east side of the country, tropical weather allows a Brazilian-type Carnival, with Comparsas dancing traditional songs in matching uniforms.

Problem: In the fall of 1958, Nasser formed a tripartite committee consisting of Zakaria Mohieddin, al-Hawrani, and Salah Bitar to oversee developments in Syria. By moving the latter two, who were Ba'athists, to Cairo, he neutralized important political figures who had their own ideas about how Syria should be run. He put Syria under Sarraj, who effectively reduced the province to a police state by imprisoning and exiling landholders who objected to the introduction of Egyptian agricultural reform in Syria, as well as communists. Following the Lebanese election of Fuad Chehab in September 1958, relations between Lebanon and the UAR improved considerably. On 25 March 1959, Chehab and Nasser met at the LebaneseSyrian border and compromised on an end to the Lebanese crisis.
In what year did Nasser and Chehab agree to end the Lebanon crisis?

Answer: 1959

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Historical aspects of the Expo line route are noteworthy. It uses the right-of-way for the Santa Monica Air Line that provided electric-powered freight and passenger service between Los Angeles and Santa Monica beginning in the 1920s. Service was discontinued in 1953 but diesel-powered freight deliveries to warehouses along the route continued until March 11, 1988. The abandonment of the line spurred concerns within the community and the entire right-of-way was purchased from Southern Pacific by Los Angeles Metropolitan Transportation Authority. The line was built in 1875 as the steam-powered Los Angeles and Independence Railroad to bring mining ore to ships in Santa Monica harbor and as a passenger excursion train to the beach.
In what year were diesel-powered freight deliveries to warehouses first used on the Expo Line?
A: unanswerable
