Technical writing

I’m stuck on a English question and need an explanation.

Using your e-text, go to page 70 and answer question 2 in the General Applications section. Do not forget to attach the documents you are using as a reference. Please read the chapter BEFORE completing the assignment.

Find a set of instructions or another type of technical document that is easy to use. Identify specific characteristics of the document, including any persuasive elements, that make it usable. (Refer to the usability questions on page 68 to guide your assessment.) Then find a technical document that is hard to use. What characteristics make it unusable? In a memo to your instructor, define specific changes that you would make in revising the document. Submit both examples along with your memo.
