According to Aristotle, the events of a tragedy are connected through cause-and-effect relationships.
A cause-effect relationship<span> is a </span>relationship<span> in which one event or </span>cause<span> makes another event happen.
</span>Hence,
<span>the events of a tragedy are connected through the plot.
Tragedy only happens when there is something wrong,so the plot in dictionary is described as </span><span>a plan made in secret by a group of people to do something illegal or harmful.</span>
I believe there was a contest but I am not sure the answer to your first question.
Here's for one of them:
Type: Nuclear
Extraction: Uranium (the fuel for nuclear energy) is typically mined using open pit or sub-surface mining. Australia, Canada, Kazakhstan are where the world's largest deposits are.
Benefits: Low cost (if you don't count building the power plant), reliable (unlike wind & solar energy which comes and goes, nuclear is readily available), no carbon emissions, produce more energy than coal power plants (most popular energy source), no air pollutants emitted (all other nonrenewable sources, aka. coal, oil, and natural gas, release harmful air pollutants)
Risks to environment: Radioactive wastes require to be safely secured away for thousands of years before they can reach safe levels, nuclear accidents can happen, mining uranium cause land disturbance, thermal pollution in nearby bodies of water or wherever cooling water is released (this can lead to dissolved oxygen levels decreasing in that body of water which can suffocate aquatic life)
Other info: Nuclear energy makes up 10% of the world's energy consumption.
