Answer:
Venture
Step-by-step explanation:
I'll assume the underlined word(s) starts after the colon sign (:) in the question.
The word that matches the description in the question is "venture".
When you venture into something, it means you are doing something in spite that the thing involves a lot of risk and sometimes, has a lot of uncertainties.
So, the exact meaning of the words after the colon sign is venture.
