Question

what should be included with constructive criticism? personal abilities negative tone opinions an alternative method

Explanation:

Constructive criticism aims to be helpful. It should offer solutions rather than just point out flaws. An alternative method provides a way forward. Personal abilities are too vague and not directly relevant to the task at hand. A negative tone is counter - productive as it may demotivate. Opinions without a basis or alternative are not constructive.

Answer:

an alternative method
