This question lacks options, options are:  

A) Problem-Based Learning  

B) Games  

C) Simulation  

D) Discovery

The correct answer is A.

Explanation:

Problem-Based Learning is a teaching methodology that aims to activate learning by investigating and discussing a real problem. This methodology uses a problem as a starting point for the acquisition of new knowledge and the conception of the students as the protagonist of the management of their learning. The objective of problem-based learning is to bring students closer to certain key ideas and present problem situations. Students learn to understand the world from complexity, it teaches them to be autonomous, independent and to have critical thinking.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
