lecture: Magnets can pull or push on each other without touching. When magnets attract, they pull together. When magnets repel, they push apart. These pulls and pushes between magnets are called magnetic forces. The stronger the magnetic force between two magnets, the more strongly the magnets attract or repel each other. You can change the strength of a magnetic force between two magnets by changing the distance between them. The magnetic force is weaker when the magnets are farther apart.

question: Think about the magnetic force between the magnets in each pair. Which of the following statements is true?

choice: (A) The strength of the magnetic force is the same in both pairs. (B) The magnetic force is weaker in Pair 1. (C) The magnetic force is weaker in Pair 2.

lecture: A solution is made up of two or more substances that are completely mixed. In a solution, solute particles are mixed into a solvent. The solute cannot be separated from the solvent by a filter. For example, if you stir a spoonful of salt into a cup of water, the salt will mix into the water to make a saltwater solution. In this case, the salt is the solute. The water is the solvent. The concentration of a solute in a solution is a measure of the ratio of solute to solvent. Concentration can be described in terms of particles of solute per volume of solvent. concentration = particles of solute / volume of solvent

lecture: The temperature of a substance depends on the average kinetic energy of the particles in the substance. The higher the average kinetic energy of the particles, the higher the temperature of the substance. The kinetic energy of a particle is determined by its mass and speed. For a pure substance, the greater the mass of each particle in the substance and the higher the average speed of the particles, the higher their average kinetic energy.

question: Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?

choice: (A) neither; the samples have the same temperature (B) sample B (C) sample A

context: The diagrams below show two pure samples of gas in identical closed, rigid containers. Each colored ball represents one gas particle. Both samples have the same number of particles.

answer: B

Rationale:

0: The temperature of a substance depends on the average kinetic energy of the particles in the substance.
1: The higher the average kinetic energy of the particles, the higher the temperature of the substance.
2: The kinetic energy of a particle is determined by its mass and speed.
3: For a pure substance, the greater the mass of each particle in the substance and the higher the average speed of the particles, the higher their average kinetic energy.
4: Each particle in sample A has more mass than each particle in sample B.
5: The particles in sample A also have a higher average speed than the particles in sample B.
6: So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
7: Because the particles in sample A have the higher average kinetic energy, sample A must have the higher temperature.
8: The answer is C.

generated_skill: The model did not accurately observe the mass and speed of the particles in each sample.

solution: Each particle in sample B has more mass than each particle in sample A. The particles in sample B also have a higher average speed than the particles in sample A. So, the particles in sample B have a higher average kinetic energy than the particles in sample A. Because the particles in sample B have the higher average kinetic energy, sample B must have the higher temperature.

lecture: Figures of speech are words or phrases that use language in a nonliteral or unusual way. They can make writing more expressive. Anaphora is the repetition of the same word or words at the beginning of several phrases or clauses. We are united. We are powerful. We are winners. Antithesis involves contrasting opposing ideas within a parallel grammatical structure. I want to help, not to hurt. Apostrophe is a direct address to an absent person or a nonhuman entity. Oh, little bird, what makes you sing so beautifully? Assonance is the repetition of a vowel sound in a series of nearby words. Try to light the fire. Chiasmus is an expression in which the second half parallels the first but reverses the order of words. Never let a fool kiss you or a kiss fool you. Understatement involves deliberately representing something as less serious or important than it really is. As you know, it can get a little cold in the Antarctic.

question: Which figure of speech is used in this text? In every cry of every Man, In every Infant's cry of fear, In every voice: in every ban, The mind-forg'd manacles I hear. —William Blake, "London"

choice: (A) anaphora (B) assonance

context: N/A

answer: A

Rationale:

0: Figures of speech are words or phrases that use language in a nonliteral or unusual way.

14: Understatement involves deliberately representing something as less serious or important than it really is.
15: As you know, it can get a little cold in the Antarctic.
16: The text uses assonance, the repetition of a vowel sound in a series of nearby words.
17: The words cry, Infant's, every, and voice share a vowel sound.
18: The answer is B.

generated_skill: The missing skill based on the wrong rationale steps is the ability to accurately identify and define figures of speech. The person incorrectly identified assonance as the figure of speech used in the text instead of anaphora. This suggests a lack of understanding and knowledge of the different figures of speech and their definitions, which is essential in correctly analyzing and identifying them in a given text.

solution: The text uses anaphora, the repetition of the same word or words at the beginning of several phrases or clauses. Blake repeats the words in every at the beginning of each phrase.

skill: Classify the figure of speech: anaphora, antithesis, apostrophe, assonance, chiasmus, understatement
