Input: Karl Popper
Among his contributions to philosophy is his claim to have solved the philosophical problem of induction. He states that while there is no way to prove that the sun will rise, it is possible to formulate the theory that every day the sun will rise; if it does not rise on some particular day, the theory will be falsified and will have to be replaced by a different one. Until that day, there is no need to reject the assumption that the theory is true. Nor is it rational according to Popper to make instead the more complex assumption that the sun will rise until a given day, but will stop doing so the day after, or similar statements with additional conditions.

Who presented a solution to the philosophical problem of induction centered around falsifiability?
Output: Popper

Input: Electric motor
Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a PMSM. The rotor material, like that of a common nail, will stay magnetized, but can also be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.

What do hysteresis synchronous motors' rotors do when slip rate decreases?
Output: becomes temporarily magnetized

Input: Gymnastics
In 2006, FIG introduced a new points system for Artistic gymnastics in which scores are no longer limited to 10 points. The system is used in the US for elite level competition. Unlike the old code of points, there are two separate scores, an execution score and a difficulty score. In the previous system, the "execution score" was the only score. It was and still is out of 10.00. During the gymnast's performance, the judges deduct this score only. A fall, on or off the event, is a 1.00 deduction, in elite level gymnastics. The introduction of the difficulty score is a significant change. The gymnast's difficulty score is based on what elements they perform and is subject to change if they do not perform or complete all the skills, or they do not connect a skill meant to be connected to another. Connection bonuses are the most common deduction from a difficulty score, as it can be difficult to connect multiple flight elements. It is very hard to connect skills if the first skill is not performed correctly. The new code of points allows the gymnasts to gain higher scores based on the difficulty of the skills they perform as well as their execution. There is no maximum score for difficulty, as it can keep increasing as the difficulty of the skills increase.

What are the two different scores?
Output: an execution score and a difficulty score

Input: Estonia
After Germany invaded the Soviet Union on 22 June 1941, the Wehrmacht crossed the Estonian southern border on 7 July. The Red Army retreated behind the Pärnu River – Emajõgi line on 12 July. At the end of July the Germans resumed their advance in Estonia working in tandem with the Estonian Forest Brothers. Both German troops and Estonian partisans took Narva on 17 August and the Estonian capital Tallinn on 28 August. After the Soviets were driven out from Estonia, German troops disarmed all the partisan groups.

When did the Germans invade the Soviet Union?
Output:
22 June 1941
