## Step 1<br />The problem is a multiple-choice question that tests your understanding of the correct use of passive and active voice in English sentences. The sentence is about Vanessa Galvez's project, which involved the installation of bioswales in Queens, New York. The sentence needs to be completed in a way that is grammatically correct and makes sense in the context of the sentence.<br /><br />## Step 2<br />Option A uses the passive voice, which is not suitable in this context. The passive voice is not appropriate when the subject of the sentence is the one performing the action.<br /><br />## Step 3<br />Option B uses the active voice, which is more suitable in this context. The active voice is more direct and clear, and it is more appropriate when the subject of the sentence is the one performing the action.<br /><br />## Step 4<br />Option C is grammatically incorrect. The phrase "has been achieved" is not suitable in this context because it implies that the action of mitigating street flooding and pollution is something that has been achieved by the bioswales, which is not the case.<br /><br />## Step 5<br />Option D uses the passive voice, which is not suitable in this context. The passive voice is not appropriate when the subject of the sentence is the one performing the action.
