<i>a) I saw a crowd, both angry and upset, sitting down, laughing --suggests whole crowd is angry and upset. </i><br/><br/><i>b) I saw a crowd, both woman and childen, sitting down, laughing.--states the crowd had some woman and some children.</i><br/><br/><i>c) I saw a crowd, woman and children, sitting down, laughing.--same as b above.</i><br/><br/>Are all three OK?<br/><br/><br/><br/>How does one know whether both x and y belongs to the group as a whole or some are x and some are y?<br/><br/><br/><br/><br/><br/>Thanks again!
