Hooktheory1 understand exercice 3.6

Hi in the book 1
In exercice part 3.6

How many notes are unstable and on strong beat

Why the 2 degree scale on a I chord in the first measure is not in the answer ?

Thank you

Hi @Subtil,

That scale degree 2 is not on a strong beat. The strong beats in a 4 beat measure are beats 1 and 3.
