1. Passive constructions: "Introverted individuals frequently encounter significant communication hurdles" uses a passive construction which emphasizes the challenges faced rather than the individuals themselves, adding a formal tone suitable for professional or academic discussions.
2. Modal verbs for possibility: "They may struggle to assert themselves" - The use of "may" introduces the possibility, not certainty, which is a nuanced way to describe potential difficulties without generalizing for all introverted individuals.
3. Relative clauses: "who might perceive them as disinterested or detached" - This relative clause adds additional information about how others might misinterpret introverted behaviors, enhancing the complexity of the sentence structure.
