It is imagery, repetition, tone
Answer:
C.
Ash became irritated by messy shoppers at S-Mart every time he had to clean up the isle.
Explanation:
A is wrong because Isle is not a name. B is wrong because you would say "I will be back." C is right because isle is like a certain area for checking out. D is wrong because the word they are thinking of is island, not isle.
If I understand the question right I would believe it to be 5 miles an hour because the course is a mile and he ran a mile in 12 minutes. We know an hour is 60 minutes so we have to divide the number of minutes he is talking from the hour. 60 divided by 12 is 5 so if he is running a mile every 12 minutes then he is running 5mph
