The air in Earth's atmosphere is made up of molecules of gases like nitrogen and oxygen. When air is cool, its molecules are dense, or packed tightly together. When air is warm, it
becomes less dense and rises, leaving behind a space with low pressure. Cool, dense air
rushes in to fill that space. The air rushing in is wind. Eventually the warm air cools and
sinks back down to earth, continuing a cycle that moves air and produces wind.
Which of the following best describes the relationship between air temperature and
density?
A
When air temperature is stable, it becomes more dense.
B
As air gets cooler, it becomes less dense.
с
As air gets warmer, it becomes less dense.
D
Air temperature cannot be used to predict air density.

answer: #1 is (a) however

explanation:

b is the answer.   i sat on the lumpy sofa, totally exhausted, with a bad taste in my mouth, wondering what i should do next.

the book's theme is the moral ambiguity of the iranian revolution, history of middle eastern relations and the process of growing up during war. it sheds light on the stereotypical views of middle eastern culture and religion.

the author explicitly portrays the issues of class disparities and racism continously throught the whole novel.

the relationship between parents and childrens, the abandonment of faith, modernity vs fundamentalism and class conflict are the 4 main panels that this novel englobes.

hope this , if you would like me to be more specific about a specific excerpt let me know : )
