Final answer:
The statement regarding the first team sport, which had variable team sizes, but eventually found two-player games to be optimal, is true.
Step-by-step explanation:
The statement suggests that the first team sport, known as pitz among the Maya and Ƶllamaliztli among the Aztecs, was played with teams that could range from one to four players, but that games with only two competitors were preferred. This is indeed true. The sport, which dates back to the Olmecs in the first millennium BCE, involved keeping a large rubber ball in motion using the hips and became an integral part of Mayan society. Well-documented historical accounts suggest that smaller team sizes eventually became the norm for this sport, as with many other team sports that followed, facilitating clearer competition and more strategic gameplay.
