- 挑战 我 第一次 这么高难度的 手术
A HSK5 past exam question is given above; the task is to reorganize the sentence fragments into a grammatical sentence. My (incorrect) answer was:
I was hoping this meant something like "my first so-high-difficulty surgery challenges me". I only chose this because the only possible verb I see listed is 挑战:
CC-CEDICT: 挑战 (tiǎozhàn) to challenge / challenge
However, there are two given answers:

It looks (to me) like there are no verbs in these examples, since 挑战 is being used as a noun. It seems like there is an omitted 是 or something.
Question: How are the sentences 我第一次挑战这么高难度的手术 and 这么高难度的手术我第一次挑战 grammatical? Where are the verbs?
