How can I rephrase this short sentence so that it is not deemed as Plagiarism?

The 20th century presents many challenges to analysts and musicologists (Surname of source, date of source). Then in the Bibliography the whole source in Harvard referencing system style. Otherwise you are going to get no marks and possibly be kicked off the course for plagiarism (they have computer programmes now to analyse papers and show up all stolen works).

Oh and anything longer than one sentence make sure it is tabulated: ............'In the growing and dynamic economy of nineteenth-century ............America, businesses sold vast quantities of goods to one ............another, mostly on credit. Therefore, business people solved ............the problem of whom to trust--how they determined who ........... was deserving of credit, and for how much. ...................................... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
