* Adverb Clause: "Sometimes advertisements are misleading"
* Subordinate Conjunction: Sometimes
* Word Modified: are misleading
Explanation:
* Adverb Clause: This clause modifies the main clause by telling us *when* advertisements are misleading. It functions like an adverb in the sentence.
* Subordinate Conjunction: "Sometimes" is a conjunction that introduces the adverb clause. It connects the clause to the main clause.
* Word Modified: The adverb clause modifies the verb "are misleading" by indicating the frequency of the action.
Therefore, the adverb clause "Sometimes advertisements are misleading" modifies the verb "are misleading" in the main clause "read labels" by specifying the frequency of advertisements being misleading.
