Task 2: Big John is coming!
Script
A bar owner in the Old West has just hired a timid bartender. This (S1) owner of the establishment is giving his new hire some instructions on (S2) running the place. He tells the timid man, “If you ever hear that Big John is coming to town, (S3) drop everything and run for the hills! He’s the biggest, nastiest (S4) outlaw who’s ever lived!”
A few weeks pass (S5) uneventfully. But one afternoon, a local cowhand comes running through town (S6) yelling, “Big John is coming! Run for your (S7) lives!”
When the bartender leaves the bar to start running, he is knocked to the ground by several townspeople rushing out of town. (S8) As he’s picking himself up, he sees a large man, almost seven feet tall. He’s muscular, and is growing as he approaches the bar.
He steps up to the door, orders the poor barkeep inside, and demands, “I want a beer NOW!”
He strikes his heavy fist on the bar, splitting it in half. (S9) The bartender nervously hands the big man a beer, hands shaking. He takes the beer, bites the top of the bottle off, and downs the beer in one gulp.
As the terrified bartender hides behind the bar, the big man gets up to leave, “Do you want another beer?” the bartender asks in a trembling voice.
“Dang it, I don’t have time!” the big man yells, (S10) “I got to get out of town! Don’t you hear Big John is coming?”


Task3: A View of Happiness
Script
Dr. Smith has proposed a reasonable, if perhaps somewhat oversimplifies, view of happiness. According to his theory, happiness might be described as a state if balance. And when human or certain animals achieve that balance, they rend to remain in that condition in order to repeat the happy feeling.
To illustrate this, we may study two magnets. When their positive and negative poles meet, they are comfortably joined, and they remain there. In other words, they have attained a balance or state of happiness. If on the other hand, one of the poles is reversed, and positive pole is presses against positive pole, there is resistance, instability, imbalance a state of unhappiness.
Animals with some degree of intelligence seem to find happiness in reinforcement. Once they have gained one or more of their goals such as food, and water, they learn to repeat the actions that led to satisfaction of those goals. This repetition or reinforcement produces a state of balance or sense of happiness.
According to this theory, only animals with a significant capacity to learn should be able to experience happiness. But in truth learning can take place through surprisingly simple short-term action such as scratching an itch, followed by pleasure, followed by more scratching, and so on. Thus learning can
