Implicit prejudice; explicit prejudice.

Explanation:

As the exercise explains, both of this cases of prejudice involves negative attitudes against a certain individual, person, group, etc. In the first case, the implicit, the attitude is not openly talked, verbalized; it's unspoken. But, in the second case, the explicit prejudice involves the awareness of hatred or negative attitude of the individual. So, overall, in the first case the person is not completely aware of the thoughts, attitude or feelings, but on the second case it is completely.
