Explanation
★A hypothesis cannot be stated in vague, general terms, so that is the answer.
★A hypothesis must be clear and specific so that it can be tested.
★So it cannot be left in vague, general terms, which could not be checked against evidence.
★It can be stated in null form, denying a relationship, which is a standard way.
★It can be stated in declarative form, as a plain statement of the expected relationship.
★It can be stated in directional form, naming the expected direction, so only vague general terms are not allowed.
