On the last day of school in Harper Lee's To Kill a Mockingbird, how does Jem let Scout know he is angry with her?

In Chapter 4 of Harper Lee's To Kill a Mockingbird, the day that Dill returns to spend his second summer in Maycomb, Scout, Dill, and Jem begin their summer by conversing about supernatural myths, which leads to Scout saying something that angers Jem.

The subject of conversation particularly turns to death and Hot Steams. When asked, Jem explains to Dill that a Hot Steam is a patch of warmth on a "lonesome road" that is actually the soul of a person "who can't get to heaven." Jem further expounds that "if you walk through him, when you die you'll be one too, an' you'll go around at night suckin' people's breath--." Jem continues to have fun spooking Dill by also disclosing that if you have to walk through a Hot Steam, you chant, "Angel-bright, life-in-death; get off the road, don't suck my breath," in order to keep the spirit at bay. At this point in the conversation, Scout stops Jem from further spooking Dill by warning Dill not to believe anything Jem is saying, stating, "Calpurnia says that's nigger-talk."

Jem scowls at Scout, which is the first point of evidence proving Jem had been angered by Scout calling his myth "nigger-talk." But, Scout doesn't realize Jem was angered until they begin playing with the old tire. It's Scout's idea to roll around in the tire, and when Jem pushes Scout in the tire "down the sidewalk with all the force of his body," Scout finally realizes just how angry she had made Jem. The tire is moving so fast that she is unable to stop it. The tire rolls right down the sidewalk to the porch of the Radley Place, where it finally comes to a stop, dumping a "dizzy and nauseated" Scout onto the walkway leading up to the house.

In To Kill a Mockingbird, how did Miss Maudie react to the events of the trial?

Miss Maudie, who does not attend the trial because she knows too well the prejudices of her town, is, nevertheless, impressed with the defense which Atticus offers on behalf of Tom Robinson.

Not one to gossip, Miss Maudie makes no comments on the trial as it goes on; however, she does remark upon it when she comes to the house for Aunt Alexandra's Missionary Tea. For, after Atticus comes home and informs his family that Tom has been shot as he tried to escape, Aunt Alexandra becomes distraught and speaks to Miss Maudie, asking her what more the town wants from him:

"...they're perfectly willing to let him wreck his health doing what they're afraid to do, they're--"

"Be quiet, they'll hear you," said Miss Maudie. "....Whether Maycomb knows it or not, we're paying the highest tribute we can pay a man. We trust him to do right. It's that simple."

Aunt Alexandra asks who these people are, and Miss Maudie replies,

"The handful of people in this town who say that fair play is not marked White Only; the handful of people who say a fair trail is for everybody, not just us....that's who they are."

From these remarks, therefore, the reader can infer that Miss Maudie is disgusted with many of the folks living in Maycomb who would afford the Ewells any credibility simply because they are white and Tom Robinson is black. And, she is repulsed by those who make a sacrificial victim of Tom simply to keep the status quo, despite the strong and righteous defense that Atticus has provided Tom. When she hears of Tom's death, she is sorry both for Tom and for Atticus, who made every effort on the unfortunate man's behalf.

What is a critical appreciation of Three Men in a Boat by Jerome?

A critical appreciation assesses the value of a book and upholds the work’s strengths and good qualities. While Three Men in a Boat is a humorous and fictional modern-day travelogue that follows a small group of friends along the River Thames for three days, it is otherwise and at its core – like Seinfeld on American TV – a show about nothing. No major mishaps or challenges occur. The characters don’t seem to change much from beginning to end. If it had been just the telling of the benign trip, it would have made for lackluster writing and boring reading. But not with Jerome K. Jerome at the helm. He, in the guise of narrator J., knows the landscape well enough to call up histories or past tales of the sites they pass. He is quick to step aside and onto seemingly relevant tangents of personal stories that range from the awkward to the absurd. Somehow his blend of past and present examples of very human behavior come together to make this book one of the most amusing adventures you are apt to pick up. Nearly every chapter has a laugh-out-loud moment, even more than a century after the manuscript was first written. Three Men in a Boat may be one of the best books you’ve never heard of.

Could the reader predict that Jem fought Bob Ewell at the end of the novel To Kill a Mockingbird, and if so where is it located in the text?

In the novel To Kill a Mockingbird, the reader could predict an attack from Bob Ewell after reading Chapter 27, but not that Jem would fight him. At the beginning of Chapter 27, Scout mentions three things that Bob Ewell does that indirectly concerns their family. Bob Ewell loses his job, attempts to break into Judge Taylor's house, and threatens Helen Robinson. Harper Lee uses these incidents to foreshadow his attack. At the end of Chapter 27, Scout practices her part in the Maycomb Pageant and says, "After that, it didn't matter whether we went or not. Jem said he would take me. Thus began our longest journey together." (Lee 340) The reader can predict that something dramatic will happen that involves Jem and Scout. The fact that Scout mentions that Jem would "take her," and they would embark on the journey "together" suggests that Jem could possibly take on a leading role in the climax of the novel. Nowhere in the text does it directly mention or foreshadow Jem fighting Bob Ewell. Lee uses imagery in the text to set the mood of the spooky, dark Haloween night and the reader can sense that something ominous will happen. Bob's attack is rather sudden and Jem yells for Scout to run. Even during the attack scene, it is not obvious to the reader that Jem is fighting Bob Ewell. Harper Lee uses Scout's confused state of mind to leave the reader wondering what actually happened in the midst of the attack. Later on in the novel, Lee reveals that Boo Radley came to the defense of the children and stabbed Bob Ewell while Jem was injured.  

For maximum protection, a car radiator needs 7 parts antifreeze to 3 parts distilled water. If the radiator will hold 21 L of the mixture, how much...

Hello!

This problem is relatively simple.

If the radiator is filled with 7 (equal) parts of antifreeze and 3 parts of distilled water (these parts have the same volume as parts of antifreeze), then there are 7+3=10 equal parts. And they together make 21 L. Therefore each part has a volume of (21 L) / 10 = 2.1 L.

Now we can easily find the volume of antifreeze and water: 7*2.1 L = 14.7 L of antifreeze and 3*2.1 L = 6.3 L of water.

The answer: 14.7 L of antifreeze will be needed, 6.3 L of water will be needed.

What was the Tet Offensive?

The Tet Offensive was a major attack that was launched by the United States’ enemies in the Vietnam War.  This offensive happened early in 1968.  It was one of the major events that helped reduce American support for the war.

By 1968, the US was fighting against the Viet Cong (communist insurgents in South Vietnam) and against the military of communist North Vietnam.  The US had been heavily involved in the war since 1964 and Americans wanted results.  The government assured the public that the US was close to victory in Vietnam.

In Vietnam, people celebrate the lunar new year (as Chinese do) rather than the solar New Year like Americans do.  Tet is the Vietnamese word that refers to the lunar New Year festival.  It is the biggest festival of the year.  During Tet of 1968, the Viet Cong and North Vietnamese launched a series of coordinated attacks around the country.  The attacks were successful at first, but the US and the South Vietnamese eventually beat them back, regaining all lost territory and inflicting huge losses on the enemy.

However, the offensive made it clear that the US was not as close to victory as the government had claimed it was.  As the American public watched coverage of the Tet Offensive, they came to realize this and more Americans turned against the government’s policy.  This helped reduce American support for the Vietnam War and it led directly to President Johnson’s decision not to run for reelection in 1968.  Thus, the Tet Offensive was one of the most important events of the Vietnam War.

What is the Bill of Rights?
