Answer:

The correct answer would be option C, 24

Explanation:

24 participants will be needed by psychologists at a minimum, to perform his experiments.

This is basically a statistical question in which the possible outcomes of the minimum number of people needed for the experiment is required.

So such questions can be solved by a simple method in which we take the number of techniques and multiply them with their descending number till 1. For example in this question, the number of techniques are 4. so it would be 4! which means we can take out the minimum number of participants by 4*3*2*1, which equals 24. So 24 is the answer.

What is the relationship between the national response framework and the national incident?
deff fn [24]

A cohesive, coordinated, and seamless national framework for domestic incident response is created when the  National incident management system  and the National Response Framework work together to integrate the capabilities and resources of various governmental jurisdictions, incident management and emergency response disciplines, non-governmental organizations, and the private sector.

What is the most likely reason the republicsame of Yugoslavia held together until the fall of communism
erik [133]
This is a little open for interpretation, but I would generally say that the best answer is that Josip Broz Tito was a very powerful leader, who kept the republics and the different groups together.

For example, we can see this from the fact that the first conflict happened in 1981: one year after his death ( a protest of Kosovans who demanded autonomy).
