General Comment:
As a follow-up study of SNACS-I, the paper clearly addresses and explains the purpose and the
necessity of the study, as well as how the information will be used. It also illustrates how
offering monetary intensive will increase the response rate due to lack of response rate from
SNACS-I and provides a detailed layout how the money will get spent. Furthermore, based on
the experience learned from SNACS-I, the new statistical method takes the challenges from
SNACS-I into consideration, and it is well explained with detailed procedures. In addition, the
new method ensures data accuracy, reduces bias, and tries to obtain a high response rate. Overall,
it is very thoughtful and shows improvement from study of SNACS-I.
