Answer:
D. Type 1.
Explanation:
                 According to the Incident Command System, in the United States the incident Type 1 requires all positions for the General Staff and the Command to be activated, as well as branches to be activated. It requires the regional or the national resources. And personnel can exceed five hundred  per the operational period.
                  The Type 1 incidents are the most dangerous incidents and most complicated incident that the Incident Command System deals with. During a Type 1 incident, all the regional as well as the national resources are alerted and is activated. An incident of this level provides activation of all the position be it be Command or General Staff personnel and also to activate all the branches. This is important because it requires  a proper coordinated approach from the root level to the national level in order to prevent it to become more disastrous.

Adolescent egocentrism is a term that David Elkind used to describe the phenomenon of adolescents' inability to distinguish between their perception of what others think about them and what people actually think in reality.[1] David Elkind's theory on adolescent egocentrism is drawn from Piaget's theory on cognitive developmental stages, which argues that formal operations enable adolescents to construct imaginary situations and abstract thinking.[2]
Accordingly, adolescents are able to conceptualize their own thoughts and conceive of other people's thoughts.[1] However, Elkind pointed out that adolescents tend to focus mostly on their own perceptions – especially on their behaviors and appearance – because of the "physiological metamorphosis" they experience during this period. This leads to adolescents' belief that other people are as attentive to their behaviors and appearance as they are of themselves.[1] According to Elkind, adolescent egocentrism results in two consequential mental constructions, namely imaginary audience and personal fable.
 
        
                    
             
        
        
        
Answer:
A market for cats would have had a positive externality. 
Because the cats would kill the rats on sight since that is their natural behavior. 
However, it is interesting to mention, that the cat's killing has been more of a "mythic" aspect of this story, since it fails to take into account that since the black death was caused by the<em> yersinia pestis</em> bacteria, cats could have been also infected, and since their interactions with humans are greater than rats or fleas, the real outcome could have been totally unexpected.
