active voice

The given sentence is in active voice.

To determine whether the sentence is written in the passive voice or active voice, we need to identify the subject and the verb.

In this sentence, the subject is "The Department of Higher Education" and the verb is "demonstrated".

If the subject is performing the action (i.e., the subject is the doer of the action), then the sentence is in the active voice. If the subject is receiving the action (i.e., the subject is the recipient of the action), then the sentence is in the passive voice.

In this case, the subject "The Department of Higher Education" is performing the action ("demonstrated"), so the sentence is in the active voice.
