Answer:
The revision of the passage that best connects ideas and adds variety is - Running is inexpensive, yet you can run on a treadmill. You can run outdoors, however, you should not run on icy roads.
Explanation:
The sentences given are short and simple. But when it comes to fusing the meaning and making it sound better, linking words are used. Here, using the words "yet" and "however" all the short sentences are joined to form one sentence which sounds well and offers the correct meaning at the same time. The flow of the sentence is better. There is less amount of jarring and stopping which helps it to connect ideas and add variety to the joined sentences.
When you break or sprain your ankle (ouch!), your ankle fractures and will begin to swell. If you break your ankle, the bone may slightly stick out, which can be easy to spot on your skin. When your ankle is sprained, it will usually swell with pain and will be a bright red color from the pain it's taking.
