Find minimum value in 2 columns based on multiple criteria

In my Test Worksheet I am looking to auto populate the column shaded in gray with a 1 or a 2 based on the following rules:

1. FIRST take the minimum value under the letter "G" and give that a value of "1".
2. Not using the value under the letter "N" next to the value used under "G", take the minimum value under "N" from the remaining 3 numbers and give that a value of "2".

If there are duplicate minimum numbers under "G", use the one which allows you to use the smallest number under "N". I hope this is doable. I manually entered the 1's and 2's in the first 9 instances to show what the results should be.

Thank you...
