I have a difficulty with structures, please help me.Thanks in advance.
Find and correct the errors in parallel in this following sentence:
By obeyingthe speed limit,we can save energy,lives,and it costs us less!

Hi duc

I guess there are a couple of ways you could reword that sentence. For example:

- Obeying the speed limit means saving energy, lives and money!

- If we obey the speed limit, we can save energy, lives, and money!

The words in green are parallel.
In the first sentence, the words in blue are also parallel.
