Can we incorporate this reply into the paper? Something like:

The participants were permanent residents of Khartoum and indigenous to northern Sudan. None of them were refugees or migrants from other parts of the country. They came from lower, middle, and upper socioeconomic strata.

There was no information on the participants of this study in terms of social class or ethnic background. This may be a problem because of the social and ethnic heterogeneity of Khartoum state, particularly the large number of migrants, including refugees, from all parts of the country.

Yes, please delete the original paragraph and replace it with Bakhiet's answer.

Dear Bakhiet & Lynn,

Peter Frost told us that he removed his earlier objection, which was :

There was no information on the participants of this study in terms of social class or ethnic background. This may be a problem because of the social and ethnic heterogeneity of Khartoum state, particularly the large number of migrants, including refugees, from all parts of the country.

So, I have modified the article at Google Docs, and replaced the above statement by Bakhiet's reply :

The participants were permanent residents of Khartoum and indigenous to northern Sudan. None of them were refugees or migrants from other parts of the country. They came from lower, middle, and upper socioeconomic strata.

Remember you can modify the link above as you wish.

Are you ok with the above changes ? Or do you want to re-write it otherwise ?

I would like to proceed with the approvement, if you're OK.

Thanks in advance.

thank you.
