Valentine has fallen under the displeasure of his father by his extravagance, and is besieged by creditors. His father, Sir Sampson Legend, offers him ÂŁ4000 (only enough to pay his debts) if he will sign a bond engaging to make over his right to his inheritance to his younger brother Ben. Valentine, to escape from his embarrassment, signs the bond. He is in love with Angelica, who possesses a fortune of her own, but so far she has not yielded to his suit. Sir Sampson has arranged a match between Ben, who is at sea, and Miss Prue, an awkward country girl, the daughter of Foresight, a superstitious old fool who claims to be an astrologer. Valentine, realizing the ruin entailed by the signature of the bond, tries to move his father by submission, and fails; then pretends to be mad and unable to sign the final deed of conveyance to his brother. Finally Angelica intervenes. She induces Sir Sampson to propose marriage to her, pretends to accept, and gets possession of Valentine's bond. When Valentine, in despair at finding that Angelica is about to marry his father, declares himself ready to sign the conveyance, she reveals the plot, tears up the bond, and declares her love for Valentine.

Question: What must Valentine do to receive the ÂŁ4000?
Answer: Sign over his inheritance to his younger brother

Question: How does Angelica trick Sir Sampson Legend into giving up the bond?
Answer: She convinces him to marry her
The menace in this story consists of dust from the tail of a comet. It consists of a colloid, analogous to smoke, that incorporates an unknown transuranic element. That element has a great affinity for metal surfaces and it weakens their surface tension, thereby enabling rapidly moving parts to cold weld themselves into solid rigidity.In the town of Mayfield high-school senior Ken Maddox is among the people fascinated by a giant comet whose path is just grazing Earth’s orbit. For the next four months Earth will float within the comet’s tail and on the first night of that sojourn Ken’s car and others begin to have problems with overheating. The next day almost all of the cars in Mayfield and other cities across the country have overheated and then refused to start. Soon all machinery is seizing up, its moving parts cold welded to each other. Because the effect is happening all over the world, people begin blaming the comet.
As the disaster becomes progressively more serious, Ken and his friends in the high school’s science club prepare to study samples of the fused metal at the local college, where Ken’s father teaches chemistry, and to try to get a sample of what the comet is putting into Earth’s atmosphere. While they work, Mayfield is cut off from the outside world and the mayor and the sheriff impose rationing against the anticipated shortages.
After a short stint in a wood-cutting crew bringing in fuel for the coming winter, Ken is called to assist in the work at the college. Along with his friends and the other scientists, he helps with experiments aimed at identifying the cause of the cold-welding phenomenon. A spectroscopic look through a telescope, compared to spectrograms of the affected metals confirms that the comet is the source of the trouble. At the same time Ken and his friends make contact with several ham radio operators around the country, intending to share information.
Little by little, as civilization crumbles around them, the Mayfield science team learns about the comet dust and how to protect machinery from it. One by one, the radio contacts cease as violence sweeps over the metropolitan areas, but aided by a clue from Berkeley just before it was destroyed Ken’s father devises a compound that will decontaminate metal surfaces. A failed attack by marauders attempting to rob the town and a flu epidemic decimate the population, but Ken has an idea that using ultrasound will coagulate the comet dust so that it will fall out of the atmosphere. Egged on by a pair of fanatics, a mob burns the college, but not before the knowledge of the ultrasonic coagulators has been shared. With people in more and more areas building coagulators and decontaminating metal parts, people around the world begin the slow and painful process of rebuilding civilization.

While they work, Mayfield is cut off from the outside world and the mayor and the sheriff impose rationing against the anticipated shortages.
After a short stint in a wood-cutting crew bringing in fuel for the coming winter, Ken is called to assist in the work at the college. Along with his friends and the other scientists, he helps with experiments aimed at identifying the cause of the cold-welding phenomenon. A spectroscopic look through a telescope, compared to spectrograms of the affected metals confirms that the comet is the source of the trouble. At the same time Ken and his friends make contact with several ham radio operators around the country, intending to share information.
Little by little, as civilization crumbles around them, the Mayfield science team learns about the comet dust and how to protect machinery from it. One by one, the radio contacts cease as violence sweeps over the metropolitan areas, but aided by a clue from Berkeley just before it was destroyed Ken’s father devises a compound that will decontaminate metal surfaces. A failed attack by marauders attempting to rob the town and a flu epidemic decimate the population, but Ken has an idea that using ultrasound will coagulate the comet dust so that it will fall out of the atmosphere. Egged on by a pair of fanatics, a mob burns the college, but not before the knowledge of the ultrasonic coagulators has been shared. With people in more and more areas building coagulators and decontaminating metal parts, people around the world begin the slow and painful process of rebuilding civilization.

Question: Where does the story take place?
Answer: In a town called Mayfield.
The menace in this story consists of dust from the tail of a comet. It consists of a colloid, analogous to smoke, that incorporates an unknown transuranic element. That element has a great affinity for metal surfaces and it weakens their surface tension, thereby enabling rapidly moving parts to cold weld themselves into solid rigidity.In the town of Mayfield high-school senior Ken Maddox is among the people fascinated by a giant comet whose path is just grazing Earth’s orbit. For the next four months Earth will float within the comet’s tail and on the first night of that sojourn Ken’s car and others begin to have problems with overheating. The next day almost all of the cars in Mayfield and other cities across the country have overheated and then refused to start. Soon all machinery is seizing up, its moving parts cold welded to each other. Because the effect is happening all over the world, people begin blaming the comet.
As the disaster becomes progressively more serious, Ken and his friends in the high school’s science club prepare to study samples of the fused metal at the local college, where Ken’s father teaches chemistry, and to try to get a sample of what the comet is putting into Earth’s atmosphere. While they work, Mayfield is cut off from the outside world and the mayor and the sheriff impose rationing against the anticipated shortages.

Question: Who decides to begin testing the affects of the comet on the Earth's atmosphere?
Answer: High school student, Ken Maddox, his friends from the science club, and his father who teaches Chemistry at a local college.
