Question

What is the function of the noun clause in this sentence?

Kam's choice, that she read the assignment, prepared her for the test

subject

indirect object

appositive

direct object

Answer 1

it's c i took the test

Answer 2

It's a tricky one but I will go for "appositive". Because;
•it adds information about Kim's choice or explains it,
•it's placed between commas
• it's a nonessential appositive because if you removed it the meaning of the sentence would still be clear.
Hope that helps..
