Input: Gamal Abdel Nasser
In January 1953, Nasser overcame opposition from Naguib and banned all political parties, creating a one-party system under the Liberation Rally, a loosely structured movement whose chief task was to organize pro-RCC rallies and lectures, with Nasser its secretary-general. Despite the dissolution order, Nasser was the only RCC member who still favored holding parliamentary elections, according to his fellow officer Abdel Latif Boghdadi. Although outvoted, he still advocated holding elections by 1956. In March 1953, Nasser led the Egyptian delegation negotiating a British withdrawal from the Suez Canal.

What was Nasser alone in supporting?
Output: parliamentary elections

Input: Bird
Most birds can fly, which distinguishes them from almost all other vertebrate classes. Flight is the primary means of locomotion for most bird species and is used for breeding, feeding, and predator avoidance and escape. Birds have various adaptations for flight, including a lightweight skeleton, two large flight muscles, the pectoralis (which accounts for 15% of the total mass of the bird) and the supracoracoideus, as well as a modified forelimb (wing) that serves as an aerofoil. Wing shape and size generally determine a bird species' type of flight; many birds combine powered, flapping flight with less energy-intensive soaring flight. About 60 extant bird species are flightless, as were many extinct birds. Flightlessness often arises in birds on isolated islands, probably due to limited resources and the absence of land predators. Though flightless, penguins use similar musculature and movements to "fly" through the water, as do auks, shearwaters and dippers.

What distinguishes birds from almost all other vertebrate classes?
Output: Most birds can fly,

Input: Szlachta
The first "free election" (Polish: "wolna elekcja") of a king took place in 1492. (To be sure, some earlier Polish kings had been elected with help from bodies such as that which put Casimir II on the throne, thereby setting a precedent for free elections.) Only senators voted in the 1492 free election, which was won by John I Albert. For the duration of the Jagiellonian Dynasty, only members of that royal family were considered for election; later, there would be no restrictions on the choice of candidates.

What dynasty was in reign during the election of 1492?
Output:
Jagiellonian Dynasty
