Answer:
Exposition
Explanation:
In these lines, we see an example of exposition. Exposition is the part of a text in which the author presents background information that the reader needs to know before reading the story. Exposition, therefore, is the first section of a text. In this case, the background information that readers need to know is that the setting has recently experienced a very destructive war. The character can remember the period before the war, and how the city was transformed.
An independent clause is a sentence or part of one that can stand alone.
So I have a feeling that the first one is correct as "My sister and I love to cook" and "we spend hours cooking together" can both stand alone yet are joined by a semicolon.
I hope this has helped
Given that Carla has already knowledge of the example from the Ecology textbook, then her reading will increase. It is called a prereading, it is a technique in which the reader will skim the text before reading it thoroughly.
Carla already has an idea on what she will be ready since she has come across the example before reading the text carefully.
