Social stratification gives some people more privileges and opportunities than the others
In social stratification perspective , the society ranks their people into some sort of hierarchy.
Using this perspective, it's clear to see that someone who was born in higher status have more opportunities than the others ( for example someone can easily inherited a company from his parents while other have to build it from the ground)
I believe the answer is Pupils narrow
When people are confronted with stressful situations, our pupils will dilated, not narrowed.
When this happen, our body will enter a fight-or-flight situation, which would be determine on our personal assessment towards whether we could handle the outcome of the situation.
One problem that blocks communication is the hierarchy within an institution. The communication is hard to disseminate below and would take the time to finally be absorbed by the working people. A decentralized communication gives faster action and results for dissemination which in effect gives member satisfaction for immediate solutions or understanding of situations.
