Question:
This question refers to the following information.
"When we were kids the United States was the wealthiest and strongest country in the world; the only one with the atom bomb, the least scarred by modern war, an initiator of the United Nations that we thought would distribute Western influence throughout the world. Freedom and equality for each individual, government of, by, and for the people—these American values we found good, principles by which we could live as men. Many of us began maturing in complacency.
"As we grew, however, our comfort was penetrated by events too troubling to dismiss. First, the permeating and victimizing fact of human degradation, symbolized by the Southern struggle against racial bigotry, compelled most of us from silence to activism. Second, the enclosing fact of the Cold War, symbolized by the presence of the Bomb, brought awareness that we ourselves, and our friends, and millions of abstract 'others' we knew more directly because of our common peril, might die at any time. . . ."

Question:
This question refers to the following information.
Now, we have organized a society, and we call it "Share Our Wealth Society," a society with the motto "Every Man a King."…
We propose to limit the wealth of big men in the country. There is an average of $15,000 in wealth to every family in America. That is right here today.
We do not propose to divide it up equally. We do not propose a division of wealth, but we do propose to limit poverty that we will allow to be inflicted on any man's family. We will not say we are going to try to guarantee any equality … but we do say that one third of the average is low enough for any one family to hold, that there should be a guarantee of a family wealth of around $5,000; enough for a home, an automobile, a radio, and the ordinary conveniences, and the opportunity to educate their children.…
We will have to limit fortunes. Our present plan is that we will allow no man to own more than $50,000,000. We think that with that limit we will be able to carry out the balance of the program.

But about the 16th of March, a certain Indian came boldly amongst them and spoke to them in broken English, which they could well understand but marveled at it. At length they understood by discourse with him, that he was not of these parts, but belonged to the eastern parts where some English ships came to fish, with whom he was acquainted and could name sundry of them by their names, amongst whom he had got his language. He became profitable to them in acquainting them with many things concerning the state of the country in the east parts where he lived, which was afterwards profitable unto them; as also of the people here, of their names, number and strength, of their situation and distance from the place, and who was chief amongst them. His name was Samoset. He told them also of another Indian whose name was Squanto, a native of this place, who had been in England and could speak better English than himself.

Question: A man owned a beautiful tract of land in a mountain resort. The property was purchased by the man and used as a family vacation retreat. About 200 yards of the man's property bordered along a lake shoreline. A fisherman lived on a stream that flowed along one boundary of the man's land and ran into the lake. When the man acquired ownership of the property, he had a channel dredged across his land from the stream to the lake at a point some distance from the mouth of the stream. The fisherman erroneously believed that the channel was a public waterway. Because the channel served as a convenient shortcut to the lake, the fisherman made frequent trips across the channel in his fishing boat. In no way did the fisherman's use of the channel cause any harm or damage to the man's property. After the man learned about the fisherman's use of the channel, he requested that the fisherman desist further entry onto the waterway. The fisherman, who until that time was unaware of the man's ownership claim, agreed. Nonetheless, the man brought suit against the fisherman to recover damages for trespass. Judgment is likely to be for whom?

Choices:

"The law of love, peace and liberty in the states extending to Jews, Turks and Egyptians, as they are considered sonnes of Adam, which is the glory of the outward state of Holland, soe love, peace and liberty, extending to all in Christ Jesus, condemns hatred, war and bondage. And because our Saviour sayeth it is impossible but that offences will come, but woe unto him by whom they cometh, our desire is not to offend one of his little ones, in whatsoever form, name or title hee appears in, whether Presbyterian, Independent, Baptist or Quaker, but shall be glad to see anything of God in any of them, desiring to doe unto all men as we desire all men should doe unto us, which is the true law both of Church and State; for our Saviour sayeth this is the law and the prophets.
"Therefore if any of these said persons come in love unto us, we cannot in conscience lay violent hands upon them, but give them free egresse and regresse unto our Town, and houses, as God shall persuade our consciences, for we are bounde by the law of God and man to doe good unto all men and evil to noe man. And this is according to the patent and charter of our Towne, given unto us in the name of the States General, which we are not willing to infringe, and violate, but shall houlde to our patent and shall remaine, your humble subjects, the inhabitants of Vlishing (Flushing, part of the colony of New Netherlands)."

high_school_us_history

Question:
This question refers to the following information.
"As a means of effecting this end I suggest for your consideration the propriety of setting apart an ample district west of the Mississippi, and without the limit of any State or Territory now formed, to be guaranteed to the Indian tribes as long as they shall occupy it. . . . There they may be secured in the enjoyment of governments of their own choice, subject to no other control from the United States than such as may be necessary to preserve peace on the frontier and between the several tribes. There the benevolent may endeavor to teach them the arts of civilization. . . .
"This emigration would be voluntary, for it would be as cruel and unjust to compel the aborigines to abandon the graves of their fathers and seek a home in a distant land. But they should be distinctly informed that if they remain within the limits of the States they must be subject to their laws. . . ."

professional_law

Question: A man was prosecuted for the alleged murder of his estranged wife. At trial, the government was allowed to present the testimony of several women who testified to having flirtatious or sexual encounters with the defendant over the past 20 years prior to the homicide. None of the testimony showed any such activity within three years of the murder date, and none of it showed any violent tendencies of the defendant or intentions expressed that he wanted to kill his wife. The defendant had an alibi for the time of the crime and presented many alibi witnesses. The government claimed that it was showing motive by proving the defendant's proclivity for extra-marital affairs over the years and therefore his bad relationship with his wife. The jury convicted him after hearing the testimony of 10 women regarding defendant's various sexual contacts with them over prior years. The defendant appealed the murder conviction, claiming that the women's testimony was prejudicial and inflammatory and showed only bad character, which is not admissible under evidentiary rules. Will the appeals court likely reverse the conviction and order a new trial?

Choices:
- Yes, the trial was unfair in presenting testimony of women going back over 20 years; it would have been proper to admit such testimony only as to the five years preceding the crime.
- Yes, the defendant did not receive a fair trial; the testimony of the women only showed his bad character but because they were old incidents and not continuing, they did not allow a permissible inference that these affairs gave him a motive to kill his spouse.
- No, if the testimony was admitted in error it was harmless error that did not sway the jury one way or another and so the defendant got a fair trial in all other respects.
- No, the testimony was admissible because it tended to show a pattern of "transferred intent" that proved the defendant's great hostility to his wife, and his need to eliminate her from his life so that he could go back to having a wild life.

Question: For many years, a husband and a wife tried to have a child, but the wife was unable to get pregnant. Her family physician had advised her that she was infertile and that it was impossible for her to become pregnant. After missing her period for three months and experiencing other symptoms of pregnancy, the wife consulted the physician. Without administering a pregnancy test, the physician examined the wife and concluded that she had the flu. He prescribed tetracycline, an antibiotic drug, which the wife took for two weeks. After discontinuing the tetracycline, the wife continued to experience nausea, fatigue, and other symptoms of pregnancy. She then consulted a different doctor, who administered a pregnancy test, which revealed that the wife was, in fact, four months pregnant. Thereafter, she gave birth to a child. When the child developed teeth, they were black and discolored. At the age of 12, the child learned that the black discoloration of his teeth resulted from the tetracycline that the wife took during her pregnancy. If a claim is brought on the child's behalf against the physician based on malpractice in not administering a pregnancy test to the woman and prescribing tetracycline, judgment is likely to be for whom?

Choices:
- The physician, because an unborn child does not have legal rights stemming from conduct that occurred before birth.
- The physician, because no duty of care is owed to an unborn child not in existence at the time medical treatment is rendered.
- The child, because a child, if born alive, is permitted to maintain an action for the consequences of prenatal injuries.
- The child, because the wife was negligent in failing to seek proper prenatal care.

The Great Society is a place where every child can find knowledge to enrich his mind and to enlarge his talents. It is a place where leisure is a welcome chance to build and reflect, not a feared cause of boredom and restlessness. It is a place where the city of man serves not only the needs of the body and the demands of commerce but the desire for beauty and the hunger for community. It is a place where man can renew contact with nature. It is a place which honors creation for its own sake and for what it adds to the understanding of the race. It is a place where men are more concerned with the quality of their goals than the quantity of their goods. But most of all, the Great Society is not a safe harbor, a resting place, a final objective, a finished work. It is a challenge constantly renewed, beckoning us toward a destiny where the meaning of our lives matches the marvelous products of our labor."
