Comments on abstract, title, references:

Dear Dr. in general: 1- The manuscript is good and appropriate with the scientific journal. 2- The researcher was committed to the structure of writing the manuscript. * Title: Good and consistent with the body of the manuscript, but it would be better if the term “consumers” were changed to “the general public” * Abstract: it's good and appropriate. * References: Good and if possible adding up to date relevant references.

Comments on introduction/background

Introduction: 1- The authors used a good way to explain motivation and orient the reader. 2- well focused on the research subject clearly presented and it was logically organized by knowledge of basic composition skills, including word choice, sentence structure, paragraph development, grammar, punctuation, spelling, and citation of references.

Comments on methodology.

1- Researchers well-presented Materials and methods on the hand of ( Population, Sampling & Sample, study instruments, Data Collection and Data Analysis). 2- Mention the ethical approval and the reliability & validity test of the questionnaire form, so I suggested defining a scale for the reliability test of the resolution (Cronbach's alpha test). as well as mention the pilot study within the practical part.

Comments on data and results

The results were clear and presented in an appropriate manner, and thus the researchers appeared able to interpret the results as required. But it would be better if the following remarks were taken into consideration: 1- Reconstruct the age groups as follows: - 20 > - 21-30 - 31-40 - > 50 2- In paragraphs ( 3.3 & 3.5 ) it should be represented in a figure or table showing the overall assessment of knowledge and practices for the study sample. 3- Add a table showing the relationship of the overall assessment of knowledge and practices.

Comments on discussion and conclusions

1- It's good and acceptable, the researchers interpreted the results well and they compared them with the other of the studies in a consistent and acceptable manner. 2- Research ethics and the limitation of the study extensively and need to be brief. 3- The conclusion must be rebuilt and more completely related to the research objectives.
