Cacophony means a harsh, discordant mixture of sound that is annoying or irritating. A combination of sounds that is not in harmony.
The words that form the clue to the meaning of cacophony are:
1) blare, battered, trumpet
2) smash, cymbals
3) anguished, screech, poorly-played saxophone
Trumpet, cymbals, and saxophone are all musical instruments. If these instruments were in very good condition and were played well, then the sounds they would have produced will be harmonious.
Then you have two iron nails.. what do you expect to happen??
The correct answer is C.
A dystopia is a "futuristic, imagined universe in which oppressive societal control and the illusion of a perfect society are maintained through corporate, technological, moral, or totalitarian control". It is the opposity of an utopia.
A world that has plunged into chaos because of the government removing the right to electricity from rebel communities is an example of a scenario for a dystopian story, since it shows how the oppresion of the government leads to a disastrous change on society's functioning. And it also shows how this scenario is maintained by the government's totalitarian control.
The rest of the answers, in which people disappear, aliens replace teenagers and a genius boy is discovered living in a library cellar, would make for good sci-fi scenarios rahter than dystopian societies.
