Your answer was wrong!
Of course, every 1H atom in a compound will
contribute a resonance signal. But consider the following example:
1,1-Dibromomethene contains two protons. It shows, however, only one
The reason for this will become quite obvious if you have another look
at the second item on page 8.

The two protons have the electronic
enironment, that is, their spatial relationships to the other atoms in
the molecule are , and the character
of the neighboring chemical bonds is for both protons.
Therefore they have the chemical shifts,
and their signals appear at positions in the
Now go back to step 8
