1. (1) Powerful new particle accelerators are important in high-energy physics, and (2) they are worth their cost because (3) they will allow scientists to produce and capture significant quantities of Z particles. (4) Z particles result from the collision of positrons and electrons, and (5) particle accelerators are needed to achieve significant numbers of these collisions. (6) Z particles are thought to be the bearers of the weak nuclear force, and (7) learning the nature of this force may lead to the development of entirely new sources of energy.
2. (1) Although Thomas Jefferson's contributions to the foundation of the country were profound, (2) as the master of Monticello, Jefferson was a monster. (3) Simultaneously with his writing the Declaration of Independence, which announced the self-evident truth that all men are created equal, he owned 175 slaves. (4) Clearly the man was a creepy hypocrite. (5) But Jefferson was also cruel. (6) He sometimes punished slaves by selling them away from their family and friends, and (7) for slaves and free blacks who ran afoul of the law, he advocated harsh, almost barbaric forms of punishment.
3. (1) All men crave material success because (2) it serves as an insurance policy against sexual rejection. This is true because (3) women love men who are successful. (4) Both men and women want power, and (5) success is the form of power women feel most deprived of. Thus, (6) women try to achieve it vicariously through men. (7) As the 5-foot 6-inch Dustin Hoffman once put it, "When I was in high school, women wouldn't touch me with a 10-foot pole. Now I can't keep them away with a 10-foot pole."
The following arguments gradually increase in difficulty. Use the method presented in this section to construct argument patterns. If a statement is redundant or plays no role in the argument, do not include it in the pattern.
