In the following questions, a sentence is given with a highlighted phrase in it. The highlighted phrase may/may not be grammatically correct. Choose the best alternative to replace the highlighted phrase so as to make the sentence grammatically and contextually correct. If no replacement is required, choose option E as your answer. The state environmental agency plans to install air quality monitors, restoring degraded wetlands, and launch public awareness campaigns before the onset of winter.

·         Rule: Parallelism means that items listed in a series must follow the same grammatical structure. ·         Reasoning: The infinitive "to" applies to all three actions: to [1] install, [2] restore, and [3] launch. All verbs in the list must stay in their plain base form (V1). Changing one verb into an "-ing" form breaks the balance of the sentence. ·         Elimination: o   (A) Incorrect because it changes the last verb to "-ing" ("launching"). o   (C) Incorrect because it mixes "-ing" ("restoring") with "to launch". o   (D) Incorrect because "for restoring" breaks the flow started by "to install". o   (E) Incorrect because "restoring" breaks the parallel pattern set by "install" and "launch".
