The correct option is this: HE RAN DOWN THE STEP, JUMPED IN HIS CAR AND QUICKLY DROVE OFF.
When writing a parallel sentence, one must ensure that the words used are in the same form. For instance, the sentence, Mary like to ski, to swim and to jump is a parallel sentence. It will be wrong to say that, Mary like to ski, to swim and jumping. In this case, you can see that the words placed in front of 'to' did not rhyme all through.<span />
1.The apostrophe after the word years is not supposed to be there. 2. The word we've is the wrong word. 3.The apostrophe in the word trial's is not supposed to be there. 4.You're is not the right word for the sentence and should be changed to your. These are the mistakes that I have found, but at the same time, recheck to make sure these mistakes can be found within the paragraph.
