Q: The modern ''jock tax'' originated in 1991, when California imposed the tax on the earnings of Chicago Bulls players who traveled to Los Angeles to play the Lakers in that year's NBA Finals. Illinois soon retaliated, imposing its own ''jock tax'' on out-of-state players--although Illinois' tax is only imposed on athletes from states that impose jock taxes on Illinois-based players. Other states followed suit; by 2014, the only U.S. jurisdictions with major professional teams without a jock tax were Florida, Texas, Washington state, and Washington, D.C. (the three states do not impose personal income taxes, while the U.S. Congress specifically prohibits the District of Columbia from imposing its income tax on non-residents who work there).
Can we conclude that do professional athletes pay taxes in every state?
A: no

Q: A player who declares for the draft will lose his college eligibility, even if he is not drafted, if he signs with any agent. Before 2016, the NCAA only allowed a player to enter the draft once without losing eligibility, but current NCAA rules now allow players to declare for and withdraw from multiple drafts while retaining college eligibility. The CBA allows a player to withdraw twice.
Can we conclude that can you go back to college after declaring for the nba draft?
A: yes

Q: Olympic sports are sports contested in the Summer and Winter Olympic Games. The 2016 Summer Olympics included 28 sports, with five additional sports due to be added to the 2020 Summer Olympics. The 2014 Winter Olympics included seven sports. The number and kinds of events may change slightly from one Olympiad to another. Each Olympic sport is represented by an international governing body, namely an International Federation (IF). The International Olympic Committee (IOC) establishes a hierarchy of sports, disciplines, and events. According to this hierarchy, the Olympic sports can be subdivided into multiple disciplines, which are often assumed to be distinct sports. Examples include swimming and water polo (disciplines of aquatics, represented by the International Swimming Federation), or figure skating and speed skating (disciplines of skating, represented by the International Skating Union). In their turn, disciplines can be subdivided into events, for which medals are actually awarded. A sport or discipline is included in the Olympic program if the IOC determines it is widely practiced around the world, that is, the number of countries that compete in a given sport is the indicator of the sport's prevalence. The IOC's requirements reflect participation in the Olympic Games as well--more stringent toward men (as they are represented in higher numbers) and summer sports (as more nations compete in the Summer Olympics).
Can we conclude that does the summer olympics have more sports than the winter olympics?
A: yes
