Can one say<br/><span style="color:#ff0000;">a. You are not very different from your brother.</span><br/><span style="color:#ff0000;">b. You are not much different from your brother.</span><br/>?<br/><br/>I think both work. Funnily enough, (b) sounds more natural to me, although 'different' is an adjective and 'much' is not used with adjectives.<br/><br/>Many thanks.
