Read this excerpt from "Rikki-Tikki-Tavi."

"But are you sure that there is anything to be gained by killing the people?” said Nag.

"Everything. When there were no people in the bungalow, did we have any mongoose in the garden? So long as the bungalow is empty, we are king and queen of the garden; and remember that as soon as our eggs in the melon-bed hatch (as they may to-morrow), our children will need room and quiet.”

"I had not thought of that,” said Nag. "I will go, but there is no need that we should hunt for Rikki-tikki afterward. I will kill the big man and his wife, and the child if I can, and come away quietly.”

How does the author use personification to characterize the snakes?

He explains the snakes’ cruel behavior by writing that they want to be “king and queen of the garden.”
He explains how the snakes will care for their children by writing that they have “eggs in the melon-bed.”

Jane works as a cashier at a small grocery store.
Her shift finishes at 3pm, but she can't leave
until her co-worker, Melissa, takes over from
her. Melissa is really nice and has been working
at the grocery store for about 3 years, and Jane
has been working there for the last 5 months.
Recently, Melissa is showing up late for work
without any explanation and because of it, Jane
is not able to leave untij 3:10pm. This really
upsets Jane and as she has to rush to get to her
computer classes. Melissa has never explained
or apologized for being late. Help Jane to solve
this situation.

Answers

Answer:

Jane should have a conversation with Melissa or her manager.

Explanation:

Maybe Melissa has something personal going on in her life and Jane should sit down with her and have a talk about why she is always late. If Melissa has no good explanation, she should go to her boss or manager and make them aware of the situation.

To help Jane I would advise you to talk to Melissa about the situation, to avoid her continuing to be 10 minutes late.

Dialogue is a form of communication in which two or more interlocutors exchange their points of view on a particular situation to establish an agreement with which they both agree.

In this case, Jane must communicate her disagreement to Melissa so that they can establish an agreement on the situation that is happening.

For example, Jane could propose to Melissa that only two days a week she can cover her for 10 more minutes or Melissa could propose that in exchange for covering her for 10 more minutes, she will receive her shift earlier so that Jane can leave more early.

The agreement reached by both interlocutors must be characterized by a balance in which neither of them gets more benefit than the other. In addition, the dialog has certain parameters that are:

RespectThe sincerityEmpathyEquality

According to the above, the best alternative for Jane to solve this problem is dialogue.

What change, if any, should be made to rambunctiously in this sentence?

The rambunctiously crowd cheered as the girls' basketball team entered the stadium as champions for the first time.
A.
no change
B.
rambunctious
C.
rambunctiousness
D.
rambunctiouser

Answers

Answer:

B. rambunctious

Explanation:

An adjective is one of the parts of speech in English language and it can be defined as a word that qualifies or describes a noun in a sentence. Some examples of an adjective are big, small, happy, tall, short, fat, rambunctious, etc.

On the other hand, an adverb modifies a verb, adjective, or another adverb. Some examples are slowly, quickly, brightly, sadly, rambunctiously, etc.

In this context, an adjective should be used to describe the noun "crowd" rather than an adverb.

Hence, the change which should be made to rambunctiously in the sentence is making it "rambunctious" and then the sentence becomes logical;

The rambunctious crowd cheered as the girls' basketball team entered the stadium as champions for the first time.

Rambunctious simply means to be energetic, boisterous, noisy and hard to control by another.

What does a simile or a metaphor the shed a squat gray mushroom mean

Answer:

Well if you know the diffrenc of a simile and a metaphor then this should anwser you question hope trhis help

Explanation:

Ever wonder what makes creative writing, well, creative? A big part of creative writing is coming up with a compelling way to express something. And similes and metaphors can be especially helpful when trying to do this. But what exactly are similes and metaphors? More importantly, what is the main difference between a simile and metaphor?

This comprehensive simile vs metaphor guide answers both these questions and gives you several examples so you can learn how to differentiate between these two key literary devices. This article also includes key tips for using similes and metaphors in your own writing.

 

Simile vs Metaphor: How Do They Differ?

 

Both similes and metaphors are literary devices used by writers to compare two unalike things, ideas, actions, etc. in a non-literal manner. The two things being compared typically have one thing in common but are completely different in all other respects.

People use similes and metaphors to make their writing more descriptive, more persuasive, more poetic, and more emphatic. Similes and metaphors are often used in fiction/prose, poetry, and song lyrics.

So what is the main difference between a simile and metaphor? Although the two devices are very similar—both serve the exact same purpose of comparing two different things in a figurative (non-literal) way—metaphors and similes are not identical.

A simile is a type of metaphor that specifically uses the words "as" or "like" to make a comparison between two things. This usually takes the form of "A is like B" or "A is as (insert adjective) as B."

By contrast, metaphors do not use the words "as" or "like." For example, you could write, "A is B" to make your comparison, even though A is not literally the same thing as B.

The main takeaway here is that all similes are metaphors but not all metaphors are similes.

Over three days in early May 1963, African American children of all ages left school to march through the streets of Birmingham, Alabama. Nine-year-old Audrey Faye Hendricks was among the youngest of about 2,000 children to participate in the Children’s Crusade. The students hoped to raise awareness about Black citizens efforts to integrate the city. Audrey was arrested and spent five nights in jail. Other young protesters were blasted by fire hoses and had police dogs turned on them.
