MBank hired El Paso Recovery Services to repossess the Pontiac Trans-Am owned by Sanchez because she was late on her loan payments. The repossessor went to Sanchez’s home with a tow truck and tried to hook the car to the tow truck. Sanchez, who was cutting her grass at the time, asked what they were doing. The repossessors didn’t respond. Sanchez then locked herself in the car to try to stall them until the police arrived. The repossessor finally towed the Trans Am on a high-speed trip, with Sanchez inside, to a repossession lot where they left the car in a fenced and locked yard. Police later rescued Sanchez. She sued MBank. Will she recover? (MBank of El Paso v. Sanchez, 836 S.W.2d 151, Tex.)

In a poll conducted by the Pew Research Center in a certain year, 2000 adults ages 18 years old and older were asked how frequently they are in touch with their parents by phone. The results of the poll are as follows:

Choose the letter of the best answer. Which of the following correctly describes a solid? A. The particles do not move at all. B. The particles are closely locked in position and can only vibrate in place. C. The particles are free to move about independently, colliding frequently. D. The particles are closely packed but have enough energy to slide past one another.

Ammonia In a piston/cylinder arrangement is at 700 kPa and 80$^{\circ} \mathrm{C}$. It is now cooled at constant pressure to saturated vapor (state 2), at which point the piston is locked with a pin. The cooling continues to −10$^{\circ} \mathrm{C}$ (state 3). Show the processes 1 to 2 and 2 to 3 on both a P–v and a T–v diagram.

Consider the three sets of indented lines. Taken together, what argument do they make? How does each set differ from the preceding lines in the stanza?
