In the sentence "That adolescence brings with it challenges that ought to be handled carefully is appropriated by the society," the pronoun "it" refers back to "adolescence." This "it" is part of the phrase "brings with it," meaning that adolescence "carries" or "comes along with" certain challenges. Here's a clearer breakdown: "That adolescence brings with it challenges that ought to be handled carefully" is a noun clause functioning as the subject of the sentence. Within this clause, "it" refers to "adolescence"—indicating that adolescence "carries along" certain challenges. "Challenges" is not the object of "it," but instead the object of the phrase "brings with it." This sentence structure might sound complex and slightly awkward. A simpler way to express it could be: “Society recognizes that adolescence brings challenges which need to be handled carefully.”

In the sentence "That adolescence brings with it challenges that ought to be handled carefully is appropriated by the society," the word “it” refers to the noun “adolescence.” Here's a breakdown of the structure: * The phrase "that adolescence brings with it challenges that ought to be handled carefully" acts as a noun clause, which is the subject of the sentence. * The pronoun "it" in this context serves as a placeholder to indicate the subject of the clause (adolescence) that brings challenges. * Therefore, "it" is not acting as an object in this sentence; it is part of the construction that clarifies what brings the challenges. So, to clarify: the challenges are what adolescence brings with it, and "it" refers back to "adolescence."

Your questions have been answered but here's an analysis of the structure of the sentence: The SUBJECT of the sentence is the long noun clause "That...carefully" The main VERB is "is". Every sentence (except for compound ones) contains just one main verb. There can be other verbs, but they play subordinate roles. The sentence contains no direct object but it does have a "predicative adjective": "appropriated". The sentence uses the linking verb "is" to connect that adjective to the subject. The subject of the sentence is described by the adjective phrase "appropriated by society". Notice that "Adolescence brings with it challenges that ought to be handled carefully" is a complete stand-alone sentence. The word "That" has the magical ability to transform any complete sentence into a noun clause.
