I am not sure what the term “assessment” means in the context of logic.
But if it is the truth value resulting from some assignments of truth values to the variables the #1 can best be done by using a truth table.
Here we need $2^4$ rows in the table.
But if we have the table, I don’t understand the point of the second question.
