Problem: Carnival:

Traditionally a carnival feast was the last opportunity to eat well before the time of food shortage at the end of the winter during which one was limited to the minimum necessary. On what nowadays is called vastenavond (the days before fasting) all the remaining winter stores of lard, butter and meat which were left would be eaten, for it would soon start to rot and decay. The selected livestock had in fact already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.

Why would all the remaining stores of lard, butter and meat left at vastenavond be eaten?
---
A: it would soon start to rot and decay


Problem: Josip Broz Tito:

As the President, Tito had access to extensive (state-owned) property associated with the office, and maintained a lavish lifestyle. In Belgrade he resided in the official residence, the Beli dvor, and maintained a separate private home. The Brijuni islands were the site of the State Summer Residence from 1949 on. The pavilion was designed by Jože Plečnik, and included a zoo. Close to 100 foreign heads of state were to visit Tito at the island residence, along with film stars such as Elizabeth Taylor, Richard Burton, Sophia Loren, Carlo Ponti, and Gina Lollobrigida.

What is the name of the official residence in Belgrade?
---
A: Beli dvor


Problem: Mammal:

The earliest clear evidence of hair or fur is in fossils of Castorocauda, from 164 million years ago in the Middle Jurassic. In the 1950s, it was suggested that the foramina (passages) in the maxillae and premaxillae (bones in the front of the upper jaw) of cynodonts were channels which supplied blood vessels and nerves to vibrissae (whiskers) and so were evidence of hair or fur; it was soon pointed out, however, that foramina do not necessarily show that an animal had vibrissae, as the modern lizard Tupinambis has foramina that are almost identical to those found in the nonmammalian cynodont Thrinaxodon. Popular sources, nevertheless, continue to attribute whiskers to Thrinaxodon.

At what time is it believed the earliest known foramina existed?
---
A: unanswerable


Problem: New York City:

In its 2013 ParkScore ranking, The Trust for Public Land reported that the park system in New York City was the second best park system among the 50 most populous U.S. cities, behind the park system of Minneapolis. ParkScore ranks urban park systems by a formula that analyzes median park size, park acres as percent of city area, the percent of city residents within a half-mile of a park, spending of park services per resident, and the number of playgrounds per 10,000 residents.

What city was rated as having the best park system by The Trust for Public Land?
---
A:
Minneapolis
