The words "the sighing trees" in the poem above are an example of

Personification

Explanation:

The term "personification" refers to a literary device in which non-human objects and ideas are given human characteristics. This device is particularly common in poetry. In this example, the trees are meant to be "sighing." This is impossible from a literal point of view, as trees are not humans and thus cannot sigh. Therefore, we can conclude that the author is using personification.

the support that the author, uses in the article facing our fears is a): a definition of the part of the brain called the amygdala.

he takes neuroscientist joseph ledoux's words by telling that by falling to distinguish between evolutionary old systems located in the amygdala and newer systems, centered in the prefrontal cortex, doctors have conflated non conscious threat circuits in the brain with circuits that underlie the conscious experience of fear. that, the author says, "leads ledoux to the jarring conclusion that the amygdala, a decades-old centerpiece of the brain's fear circuit, does not underlie the conscious feeling of fear".

despite this, the author points out in the article that that is a controversial notion and that evidence, in animal and humans, supports the idea that core emotions can exist outside of conscious awareness.

i would say the correct answer is not concrete.
