Only recently have scientists determined why Harappan civilization disappeared, and the answer is climate change.

What type (sentence structure) of the underlined part?
Is it inverted sentence?
I'm lost in this sentence. Could you help my honorable expert, please?
Thanks__

Yes, you are right. It's an inverted sentence.

So far I know, in Inverted sentence, i have to keep subject after 'verb'. So, 'have' is for subject 'scientists', right? The question is: why the verb 'determined' has been used again for the same subject 'scientists' ? How a 'subject' posses 2 'verbs' in its left hand side and right hand side at a time?
Thanks EducationAisle for your kind feedback.

Don't worry about the fact that the subject is in the middle of have and determined. Neither have nor determined (alone) is the verb. The verb is have determined (have is a helping verb).

Technically speaking, determined is not a verb here, but a past participle.

Here is an example of simple sentence:
Scientists have done the work. (Assertive sentence)
==> Have Scientists done the work? (Interrogative sentence)
If we convert any assertive sentence to interrogative sentence, then we put the auxiliary verb before subject. And if the sentence keeps both auxiliary verb and present participle, then we put the 'subject' in the middle of both "auxiliary verb and present participle".

Here the inverted sentence is not the interrogative sentence. So, WHY do we put 'subject' in the middle of the ''auxiliary verb and present participle"?
Thanks
