    I guess they mean negative feedback?

    Your course should have taught you enough to answer that question, but if they didn't, Google negative feedback to learn about its effects.

    At first, you have to ask yourself: Whar are the most important parameters determining the properties of the amplifier?
    And - as a second step - you can try to find out which of these parameters could be influenced by negative feedback.

    And then Google positive feedback, which is generally undesirable in an amplifier.

    ....or try to find out by yourself (after learning about negative feedback) WHY positive feedback is generally undesirable.
