jaka uzyc właściwą formę słówka 'origin' w zdaniu

garlic is believed to have......... in the siberian desert

Garlic is believed to have ORIGINATED in the siberian desert.

Quasi passive - I love it!

origin jest czasownikiem? (przepraszam za pytanie:), ale nie wiem skąd taka forma 'originated'?

I'm almost certain that the task requires transformations - so one of the possible transformations of the noun 'origin' is the verb 'originate'.

kurcze zdecyduj sie bo w innym watku napisales
she is.....a headache

In that situation you had to choose one answer out of the four provided. And the very correct one was 'b) had'.
