Explanation
Sentence # 12 "I did some of the problems in my head, the last answer I wrote, and when the bell rang I stopping writing" needs to be revised because it does not have a parallel structure "did", "wrote" and "stopping". To review this sentence to create a parallel structure it is necessary to change the last verb "stopping" to "stopped" to maintain the parallel structure which establishes one verbal tense. Moreover, the best tense is simple past because the author was talking about an past event. According to the above, the correct answer is B.

It is a scalar quantity, that is, it has only magnitude and no specific direction and it is measured in meter per second. A high speed value implies that an object is moving very fast while a low value indicates that the object is moving slowly. For the two buses given in the question, they both moved the same distance in the same amount of time.
The answer should be (C) Present perfect. This is because 'has' stands for present and 'eaten' is past participle, which makes it present perfect.
