Motivation is necessary in order to succeeD.Whether you are working out to feel and look better, participating in the 'Day of Silence' to support a cause, or working hard in school to get good grades and get accepted at one's college of choice, everything that people do has a motive behind it.However, motivation is a quality that many high school students seem to lack.

However, in order to improve the Virginia Tech website, I would include a suggestion box after the checklist so after completing the list, after reading the suggestions from this box, one could have some sort of plan of action.What is the author trying to approve with the examples in paragraph 1 ?A.People have various life choices.B.Efforts are needed for us to get anywhere in lifE.C.People's life stylE.choice determines their social status.D.People's various actions are driven by corresponding motivations.
