Hearing impairment presentation assessment and intervention

i have these two Journal article need to be presented in a powerpoint + 5 bullet point handout style.
start by giving a brief background based on what the authors discuss in their introduction sections, then identify the hypothesis or expectations of the authors followed by a brief statement about their methodology and sample, next you should discuss what the authors found and why it is important (this can be typically found in the discussion section and will be easier to understand there as opposed to the results section).
i will have the 2 journal article upload as soon as the case is ready.
please help me through. thank you so much
