Determine the function of the hilighted dependent clause in each of the followings.
The bankers need to know what they should do.
A. Noun clause
B. Adjective clause
C. Adverb clause
D. None of the above
Correct Answer : A.
This clause does not tell you which bankers need to know, but rather, it tells you what they need to know -- since it answers the question what? (and acts as the direct object of to know), it is a noun clause.
