practice\nnow put your learning into practice! from the following pairs of sentences, select the one which is correct.\n○ running across the floor, the rug slipped and i lost my balance.\n○ as i was running across the floor, the rug slipped and i lost my balance.
Answer
Brief Explanations:
The first sentence has a dangling modifier. "Running across the floor" seems to modify "the rug" which is incorrect. The second sentence clearly shows that "I" was running, making it grammatically correct.
Answer:
As I was running across the floor, the rug slipped and I lost my balance.
