Answer:
To emphasize the seriousness of what is about to happen. 
Explanation:
In "Big finish," by Erin Michelle Jendras, when the woman on the screen gets quiet as soon as the numbers get to ten, she does so because it´s time for the final countdown. As soon as the count gets to zero, the reader will discover that Terra, the planet earth humans had to escape years before, is being destroyed. The sudden silence of the woman broadcasting the live event is a small detail that makes it clear that what´s about to happen is an important event. 
 
        
             
        
        
        
Answer: It is a simple sentence.
Explanation:
Compound sentences contain a <em>FANBOYS</em> (for, and, nor, but, or, yet, so) coordinating conjunction following a comma. Since this sentence does not contain a <em>FANBOYS</em> conjunction after a comma, it is a simple sentence.
example compound sentence:
I was hungry, so I made myself a sandwich.
example simple sentence:
I made myself a sandwich because I was hungry.
 
        
             
        
        
        
Answer:
The poem's allusion to the 1982 Brixton riot:
C. illustrates the strong feelings associated with the poem's subject matter.
Explanation:
This excerpt was taken from part XXIII of Derek Walcott's "Midsummer". Born in 1930 in Saint Lucia, Walcott received several awards for his works, including the Nobel Prize. He passed away in 2017.
The simile we are analyzing here compares the summer leaves to the Brixton riot. This may seem to be quite an unlikely comparison, which is probably what the author was aiming for. It is quite powerful to compare a season to a riot and its violence. As a matter of fact, as the poem goes on, the author continues to do so. He compares, for instance, leaves and branches to cattle being whipped. All of that unusual comparison aims to illustrate the author's feelings toward his subject matter, which is clearly quite strong.
 
        
             
        
        
        
Romiette and Julio is about a inter-racial relationship, that takes a turn for the worst. It first begins when Julio moves from Texas to Cincinnati to get away from gang violence. He goes to a mostly African American high school. Little did Julio's parents know, that this high school has gangs too. He doesn't have much friends but he gets through the first few weeks. He goes on a chat room and meets Romiette but they don't find out that, they live in the same city and go to the same school, until later. When they do befriend each other, a certain gang called the Devil Dogs who was an African American gang, don't like the fact that the two are getting close so they warn Romiette and Julio. She doesn't think much of it but they think of a plan to make fun of the Devil Dogs. The plan worked but the Devil Dogs weren't going to take the humiliation. A few days later the Devil Dogs kidnap Romiette and Julio and set then in a lake during a thunderstorm. They end of getting out of the boat and back on to land but Romiette is going in and out of conciseness. Julio tries to find shelter but trips and falls in the mud. He then decides to go in the nearest ditch to stay alive with Romiette in hes arms. Police soon finds them and they are sent immediately to the hospital to get checked out. The Devil Dogs are in custody art the police and are probably gonna get charged for kidnapping. Soon, Julio and Romiette are back to normal and neither aren't bothered again about their relationship.
