Richter's Predictor: Modeling Earthquake

I am new to this competition I have a question related to test data uploaded on the site
with file name “submission_format.csv”
can we use this as test label data(y_test) for model evaluation or this is provided only as reference as to how to submit csv file with format
because for all entries in file “submission_format.csv” the damage_grade is 1 which is confusing.
