1. Use of passive voice: "are highly favored among adventurous young individuals" - This structure emphasizes the sports rather than who favors them, which is a sophisticated way to shift focus in a sentence.
2. Complex sentence structure: The sentence "These sports not only offer excitement and a physical challenge but also involve a strong community culture" uses a correlative conjunction (not only... but also), which helps in balancing two equally important aspects of the sports, making the sentence more informative and engaging.
