Asource must be cited

c. there are no “musts” when it comes to citing sources

d. a source should always be cited

The answer is D: a source should always be cited.

Plagiarism, that is to say, the use of another person´s words or ideas without giving due credit to that person, is a form of fraud or literary theft.

I order to avoid it, when quoting, paraphrasing or even mentioning somebody else´s ideas or words, one should always cite the source or the author of such words or ideas. In academic fields there are guidelines, called formatting styles, like MLA, determining how to cite a source.  

yes, post it and i can try to you out.

hmm, sadly there is no dialogue. there is no place in the story where he is talking to anyone. it's more of just describing what he eats and where he sleeps. you have to become anne frank, give details of where you are, what other folks look like, how the environment is. have a little bit of dialogue tell of what people are specifically saying. anne frank talked about her entire household including the people, the objects, the lighting, the food they ate, and even the smell in the air. there has to be more to your diary entries, the whole story in its current state is only about peter van daan, the food, the sounds, and where he sleeps. also he seems to be writing only once a year yet more than that happened from day to day. for a friend, i can you write it out, if you want.
