Dad has a secret fishing spot (where he catches the most fish.

Had to look for the complete instruction for this and here is my answer.
Based on the given sentence above, we can say that the one being enclosed in the parenthesis  (where he catches the most fish) functions as an adjective clause. What makes this an adjective clause is that, it defines a noun which is the word "spot". Hope this helps.

All you have to do is pee in some of the number so that's between x 3 the p is like the prime number so i'll let you do is check for primus pride i've been 7 3 4 5 and 6 and you can you can just times or / that
