In "Farming Like the Incas" by Cynthia Graber, she explains what made Incan farming so remarkable. They successfully farmed in the Andes, which are considered "some of the tallest, starkest, mountains" and were able to harvest on terrain that is steep and difficult to move on. They were able to overcome climate difficulties by building terraces, irrigation systems, and cisterns.
Without the humor, we should be worried about Greg. This line tells us how bad he feels at school because of the simple fact of existing. Imagine how bad he must feel to look a solution for his existence. He probably feels as if he does not belong in there, like a freak kid that everyone makes fun of him. He can create depressive behaviours such as isolation, sadness, etc. that can lead him to, dramatically speaking, commit suicide. This is not a joke, he is probably having a mental illness because he does not feel comfortable with his life in high school.
The following terms apply: UNNECESSARY, NON ESSENTIAL AND NON RESTRICTIVE.
These three terms are used interchangeably to describe a particular clause or phrase in a sentence.
A clause or phrase is said to be non essential if its removal from the sentence does not affect the main idea or the meaning of the sentence. A sentence will still retains its meaning if a non essential phrase or clause is remove from it. For example, look at this sentence: Faith, who always comes first in her class, is a very intelligent girl. The non essential phrase in the sentence is 'who always comes first'. If this phrase is removed from the sentence, the sentence will still retain its original meaning and the sentence will now read like this: 'Faith is a very intelligent girl'.
