4x 2 Our communities, the economy and much of our lives are organized around our ability to travel easily and efficiently from home to work or school, to shop or play, to receive medical care or just for the sheer pleasure of traveling. (1) This freedom has certain costs that accompany its many benefits. (2) Vehicles public and private have to be purchased and operated; (3)roads must be built and maintained; laws must be enforced so many people can travel at the same time; and (4)hundreds of thousands of accidents inevitably occur. Which revision changes the underlined clause labeled (3) in paragraph 2 from passive voice to active voice? A roads, public and private, must be built and maintained B roads must be maintained by public and private donations C the Department of Transportation (D.O T.) must build and maintain roads D the Government roads, public and private, must be maintained by those who built them

## Step 1<br />The problem is asking us to identify which option changes the underlined clause labeled (3) in paragraph 2 from passive voice to active voice. The original clause is "roads must be built and maintained". In passive voice, the subject of the sentence is acted upon by the verb. In this case, the roads are being acted upon by the action of being built and maintained.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />### Option A: "roads, public and private, must be built and maintained"<br />This sentence is still in passive voice. The roads are still being acted upon by the action of being built and maintained.<br /><br />### Option B: "roads must be maintained by public and private donations"<br />This sentence is also in passive voice. The roads are still being acted upon by the action of being maintained.<br /><br />### Option C: "the Department of Transportation (D.O.T.must build and maintain roads"<br />This sentence is in active voice. The Department of Transportation is performing the action of building and maintaining the roads.<br /><br />### Option D: "the Government roads, public and private, must be maintained by those who built them"<br />This sentence is in passive voice. The roads are still being acted upon by the action of being maintained.<br /><br />## Step 3<br />Based on the analysis, only option C changes the sentence from passive to active voice.
