Which one of the below is a better statement, mgmat prefers first, can someone explain why ?
My child has better hygiene than my sister’s children; neither of her boys ever seems to wash his hands.
My child has better hygiene than that of my sister’s children; neither of her boys ever seems to wash his hands.
Here we are comparing my child to my sister's children... hence 1 is correct
in second sentence "that" has referent Hygiene but it makes comparison invalid because child cannot be compared with hygiene of children. Moreover, for second to be correct the sentence has to be re-arranged as " Hygiene of my child has better than that of my sister's children...." now in this case "that" is correct because we are comparing hygiene of someone to hygiene of other one.
