Thanks.

I soooooooo want to answer the second ques but not sure if i’m correct. I think it has to do with the sounds again. Right or wrong? A simple Yes/ No/Sort of, would suffice. If yes, then i’m pretty sure i’ve cracked it; if not, then in the words of Poirot, have to use the little grey cells a bit more.

One more thing, are you absolutely, positively, 100% sure that the letter d is present in both groups 1 and 2?

Aha … I think you are on to something … yes, the “d” was a typo in group 2.
