question: Read the following excerpt from a student essay. How can the writer best improve his or her sentence fluency? The Western Australian pitcher plant is a carnivorous plant native to southwestern Australia. The pitcher is a perennial herb. It is approximately eight inches high. Growing in swampy or sandy soils, it obtains needed nutrients from insects and other small prey. The pitcher plant has carnivorous leaves. The leaves act as traps, or pitchers. The pitchers produce enzymes for digesting prey. Prized among collectors, the plant is considered a vulnerable species.

choice: (A) by combining sentences (B) by varying how sentences begin (C) by using shorter sentences

gold answer: A

wrong prediction:

Rationale:

0: During peer review, you read and respond to a fellow student's writing.
1: While there are many methods and strategies that you can use for reviewing a text, it is generally helpful to frame your suggestions in concrete and constructive ways and to consider the following areas for revision: Ideas and development: Does the writer express a clear idea and develop it with evidence, examples, or analysis?
2: Organization: Does the writer order ideas in a clear, logical way so that they build on one another and are easy to follow?
3: Voice: Does the writer maintain an appropriate voice, such as a formal and objective voice in an academic essay or an engaging and expressive voice in a narrative essay?
4: Sentence fluency: Does the writer use sentences that vary in structure and length to create a sense of rhythm and flow within and between sentences, or does the writing sound choppy, rambling, or repetitive?
5: Word choice: Does the writer use words accurately and precisely to create clear, effective, and engaging writing?
6: Grammar and mechanics: Does the writer follow appropriate conventions, using accurate spelling, punctuation, and grammar to create writing that is correct and easy to read?
7: The writer could best improve his or her sentence fluency by varying how sentences begin.
8: For example, the writer could shorten the second sentence to make it more concise or revise the third sentence to begin with a subordinating conjunction.

question: Which solution has a higher concentration of blue particles?

choice: (A) Solution B (B) neither; their concentrations are the same (C) Solution A

context: The diagram below is a model of two solutions. Each blue ball represents one particle of solute.

gold answer: B

wrong prediction:

Rationale:

0: A solution is made up of two or more substances that are completely mixed.
1: In a solution, solute particles are mixed into a solvent.
2: The solute cannot be separated from the solvent by a filter.
3: 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.
4: In this case, the salt is the solute.
5: The water is the solvent.
6: The concentration of a solute in a solution is a measure of the ratio of solute to solvent.
7: Concentration can be described in terms of particles of solute per volume of solvent.
8: concentration = particles of solute / volume of solvent In Solution A and Solution B, the blue particles represent the solute.
9: To figure out which solution has a higher concentration of blue particles, look at both the number of blue particles and the volume of the solvent in each container.
10: Use the concentration formula to find the number of blue particles per milliliter.
11: Solution A has more blue particles per milliliter.
12: So, Solution A has a higher concentration of blue particles.
13: The answer is C.

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

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

context: The images below show two pairs of magnets. The magnets in different pairs do not affect each other. All the magnets shown are made of the same material.

gold answer: C

wrong prediction:

Rationale:

0: Magnets can pull or push on each other without touching.
1: When magnets attract, they pull together.
2: When magnets repel, they push apart.
3: These pulls and pushes between magnets are called magnetic forces.
4: The stronger the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
5: You can change the strength of a magnetic force between two magnets by changing the distance between them.
6: The magnetic force is weaker when the magnets are farther apart.
7: Distance affects the strength of the magnetic force.
8: When magnets are farther apart, the magnetic force between them is weaker.
9: The magnets in Pair 1 are farther apart than the magnets in Pair 2.
10: So, the magnetic force is weaker in Pair 1 than in Pair 2.
11: The answer is A.

question: What does the metaphor in this text suggest? Conscience is a man's compass. —Vincent van Gogh

choice: (A) Your conscience shows you where you're headed. (B) Your conscience guides you to act the right way.

gold answer: B

wrong prediction:

Rationale:

0: Figures of speech are words or phrases that use language in a nonliteral or unusual way.
1: They can make writing more expressive.
2: A metaphor compares two things that are not actually alike without using like or as.
3: The snow formed a blanket over the town.
4: The text uses a metaphor, comparing two things that are not actually alike without using like or as.
5: The metaphor conscience is a man's compass suggests that your conscience shows you where you're headed.
6: A compass shows you where you're going.
7: Like a compass, your conscience shows you what you believe and what you should do.
8: The answer is A.

question: Which i in column 2?

choice: (A) the grocery store (B) the library (C) the park (D) the gas station

gold answer: B

wrong prediction:

Rationale:

0: A grid is made up of lines of squares.
1: They are organized in rows and columns.
2: A grid can help you use a map.
3: A row is a line of squares that goes from side to side.
4: Rows are marked with letters.
5: A column is a line of squares that goes up and down.
6: Columns are marked with numbers.
7: The grocery store is in column 2.
8: The answer is A.

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

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

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.

gold answer: A

wrong prediction:

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 the two samples has the same mass, but the particles in sample A have a higher average speed than the particles in sample B.
5: So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
6: Because the particles in sample A have the higher average kinetic energy, sample A must have the higher temperature.
7: The answer is B.

question: Will these magnets attract or repel each other?

choice: (A) repel (B) attract

context: Two magnets are placed as shown.

gold answer: A

wrong prediction:

Rationale:

0: Magnets can pull or push on each other without touching.
1: When magnets attract, they pull together.
2: When magnets repel, they push apart.
3: Whether a magnet attracts or repels other magnets depends on the positions of its poles, or ends.
4: Every magnet has two poles: north and south.
5: Here are some examples of magnets.
6: The north pole of each magnet is labeled N, and the south pole is labeled S. If opposite poles are closest to each other, the magnets attract.
7: The magnets in the pair below attract.
8: If the same, or like, poles are closest to each other, the magnets repel.
9: The magnets in both pairs below repel.
10: To predict if these magnets will attract or repel, look at which poles are closest to each other.
11: Both poles of each magnet line up with both poles of the other magnet.
12: The north pole of each magnet is closest to the south pole of the other magnet.
13: Opposite poles attract.
14: So, these magnets will attract each other.
15: The answer is B.
