What rhetorical techniques does Roosevelt use in the excerpt from the speech you read and listened to? What effects do the techniques have? I found the answer

Roosevelt uses parallelism when he discusses the material problems the nation faces. The way the sentences connect together mimics the problems the nation is facing- they are all piling up on one another. to the listener, the problems are emphasized by the repition of words. The parallel sentence structure is an effective way to present these ideas.

Incomplete question. I inferred you want an explanation of the term parallelism.

Explanation:

The term parallelism is a literary device used in speech or literature. It involves the use of words or phrases with a close grammatical structure. It means the words or phrases are used repeatedly in other to create a clearer understanding of what is been said.

For example, Roosevelt used the expression "It can be helped by" repeatedly in the excerpt below,

"It [a better use of the Nation’s natural resources] can be helped by insistence that  the Federal, State, and local governments act forthwith on the demand that their  cost be drastically reduced. It can be helped by the unifying of relief activities  which today are often scattered, uneconomical, and unequal. It can be helped by  national planning for and supervision of all forms of transportation and of  communications and other utilities which have a definitely public character."

By so doing he was able to make the problems stand out.

sensory details?

so i`m assuming you are writing something from a bats (the animal) point of view. if this is the case, you can use sights, sounds, feelings, and tastes.

and idk what you mean by domain, but all of the sensory details will depend on where the bat is.

a bat doesn't see color very well, so its surroundings will be dulled.

it can hear super well. so maybe it can hear the insects on the ground

feelings. you can imagine how a bat would feel from its perspective. it all depends on where it lives.

maybe it can taste the salt in the air, or smell water, or something. all of these details are completely dependent on where it is located.

hope this .

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
