What is the main characteristic of structured data coupling?

Data passed via parameter lists is structured (correct)
Non-structured data passed via parameter lists
Data from one module tells another module what to do
Data is not controlled by the sending module

Which of the following best describes structured data coupling?

Loose connections between modules
Data formats are controlled by receiving module (correct)
Complete dependence between modules
Sending module decides what to do with data

What is the goal of structured data coupling?

Minimize interactions between modules
Give complete control to the sending module
Allow the receiving module to structure the data (correct)
Maximize dependence between modules
