Asking questions about the text makes reading easy for some people. It is a matter of elaborating a questionnaire about reading, which is answered by the reader, of course. However, there is the possibility of even asking a question next to each paragraph that you deem most important. So when you read the question you asked, you will know what the paragraph in question is about.
The best answer for this is the third option: ASKING QUESTIONS. This is one of the strategies in reading comprehension wherein one becomes aware whether they understood what they are reading. This also guides the reader on what to look and expect to the content as this will answer their questions.
