1. QuestionMultiple choice

A student tests whether fertilizer affects plant growth. Which variable should be kept constant?

Please select an answer first.

Correct answer: A

The correct answer is The amount of water given to each plant.

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: Keeping water constant prevents it from becoming a competing explanation for differences in growth.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

Keeping water constant prevents it from becoming a competing explanation for differences in growth.

2. QuestionMultiple choice

A graph shows that enzyme activity rises as temperature increases to 40 degrees Celsius, then falls at higher temperatures. What is best supported?

Please select an answer first.

Correct answer: B

The correct answer is The enzyme has an optimum near 40 degrees Celsius under these conditions..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: The peak in the graph identifies the temperature at which measured activity is greatest.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

The peak in the graph identifies the temperature at which measured activity is greatest.

3. QuestionMultiple choice

In a food web, a decrease in plant populations would most directly reduce the available energy for which organisms?

Please select an answer first.

Correct answer: C

The correct answer is Primary consumers.

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: Primary consumers obtain energy directly from plants, so less plant material reduces their food supply.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

Primary consumers obtain energy directly from plants, so less plant material reduces their food supply.

4. QuestionMultiple choice

A rock sample contains a radioactive isotope with a half-life of 10,000 years. After 20,000 years, what fraction of the original isotope remains?

Please select an answer first.

Correct answer: D

The correct answer is One-fourth.

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: After one half-life one-half remains; after two half-lives, one-half of that amount, or one-fourth, remains.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

After one half-life one-half remains; after two half-lives, one-half of that amount, or one-fourth, remains.

5. QuestionMultiple choice

Two groups receive the same treatment, but one group is measured before and after the treatment while the other is measured only after it. Why is the second group useful?

Please select an answer first.

Correct answer: A

The correct answer is It provides a comparison for judging whether the treatment changed the outcome..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: A comparison group helps researchers distinguish treatment effects from changes that might occur without the treatment.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

A comparison group helps researchers distinguish treatment effects from changes that might occur without the treatment.

6. QuestionMultiple choice

A researcher finds that as dissolved oxygen increases, the number of fish observed also increases. Which conclusion is justified without further evidence?

Please select an answer first.

Correct answer: B

The correct answer is The two measured variables are positively associated..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: The data support an association, but a causal claim would require additional controls and evidence.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

The data support an association, but a causal claim would require additional controls and evidence.

7. QuestionMultiple choice

Which observation best supports the claim that a substance is acidic?

Please select an answer first.

Correct answer: C

The correct answer is It turns blue litmus paper red..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: Turning blue litmus red is a standard indicator of acidic behavior.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

Turning blue litmus red is a standard indicator of acidic behavior.

8. QuestionMultiple choice

A population of insects becomes resistant to a pesticide over many generations. Which process best explains this pattern?

Please select an answer first.

Correct answer: D

The correct answer is Natural selection favors insects with resistance traits..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: Inherited variation allows resistant insects to survive and reproduce more successfully when the pesticide is present.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

Inherited variation allows resistant insects to survive and reproduce more successfully when the pesticide is present.

9. QuestionMultiple choice

A circuit has a battery, wires, and a bulb, but the bulb does not light because the switch is open. What change would complete the circuit?

Please select an answer first.

Correct answer: A

The correct answer is Close the switch..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: Closing the switch creates a continuous conducting path for electric current.
  3. Check the choice: Eliminate choices that do not answer the exact question or conflict with the passage, data, or stated conditions.

Closing the switch creates a continuous conducting path for electric current.

10. QuestionMultiple choice

Which result would most strongly support the hypothesis that sunlight increases the rate of photosynthesis?

Please select an answer first.

Correct answer: B

The correct answer is Plants exposed to more light produce more oxygen per hour while other conditions remain constant..

  1. Identify the task: Determine whether the question asks about language, quantitative reasoning, reading evidence, science data, or test strategy.
  2. Use the evidence: The controlled comparison changes light while measuring oxygen production, the predicted outcome of photosynthesis.
