What are some techniques found in "Tears of Nature" that can be supported with context?

"Context to explanations" means the use of lines from a poem or passages from a text that act as real support for a point or statement or observation that the writer makes.

In a broad sense, all literary analysis is a type of argument; that is, the writer makes claims about a literary work, and for these claims to be substantial and valid, there must be support (context) from the work itself which, then, verifies...

"Context to explanations" means the use of lines from a poem or passages from a text that act as real support for a point or statement or observation that the writer makes.

In a broad sense, all literary analysis is a type of argument; that is, the writer makes claims about a literary work, and for these claims to be substantial and valid, there must be support (context) from the work itself which, then, verifies these claims. 
"What not to write" is anything that does not really support the points/observations/statements that the writer makes.

Thus, writers may well ask themselves, "Why do I think this?/ How can I prove this?" when they write a thesis statement or state an observation. Also, it sometimes works better for particular writers to search for facts, examples, "evidence" first, before creating a thesis. In this way, a thesis can then be formed for which there is certain explanation and support.

Here is an example of context for explanations, using "Tears of Nature":

[thesis] In the poem "Tears of Nature," there is an urgency created for the reader to attend to the problem of global warming and environmental destruction.

[statement] Emotional appeal about the danger of global warming is made to the reader by the author's use of refrain. 
[context] This refrain is "I think I just heard Mother Nature cry."

[statement] Rational appeal is also made to the reader with examples of damaging practices by humans.
[context] This appeal is made through the use of examples, such as the ozone hole in the sky, "pollution in the sea," the mention of certain species that have gone extinct due to pollution, the burning of coal in the chimneys, etc. (Each stanza has an example) 

--The main thing to keep in mind in providing context to explanatory statements is to be certain that the context really does support the statement that is made. If it is not a viable support, do not use it.
