Consider these facts: The tennis champion Williams sisters are a generationapart, according to the Pew Research Center. Venus, born 1980, is part of“Gen X”; Serena, born 1981, is a “Millennial.”
As a tennis player, I find this line very intriguing. In the world of tennis, there is currently a rise of "NextGen" stars born in the late 90s and early 2000s. While considered parts of two different "generations", they are all roughly the same age and compete at the same level. The Williams sisters dominated the game side by side despite being born in different generations. This point is a solid start to conveying the writer's argument. (Informative)
