Answer 2

'Have demonstrated' is the present perfect tense.

-This is the answer.

About finding the verb:

• When we read the sentence we will find words 'working', 'have demonstrated' and 'to usher' -three form so verbs used.
• But 'working' here is not a continuous tense. It is used as an adjective. It is used to qualify the nouns -teachers and students. So 'working' is not a verb here.
• The words 'to usher' is an infinitive and not a verb.
• Infinitives are verbs that act as the subject/ object/ adverb of the sentence. They can act as the direct or the indirect object.
• They are in the form of 'to' + verb. Infinites usually answer the question 'for what' in the sentence. Thus 'to usher' is an infinitive and not a verb.
• The verb 'have demonstrated' is the only verb that does the role of a verb. It is in present perfect tense because we have 'have + past participle of 'demonstrate'.
