1) Abbreviated labels referring to the actual questions are added in the Figure 3 (Figure 2 in the revision). But 2) we keep the original percentages (round to one decimal place).

Figure 3. The plot is well presented. A few minor notes for improvement: 1) Please consider adding short or abbreviated labels referring to the actual question, instead of codes (e.g., GH3-Q10). This would make it easier for the reader; 2) Round the percentages to the nearest whole number.
