Sample Questions

1. Gigi, a geology student, collected field samples of rocks. On one day, every rock she collected was quartz, and she collected every piece of quartz she saw. Which conclusion must be true?

  • A. The only rocks Gigi saw that day were quartz.
  • B. Gigi collected every rock she saw that day.
  • C. There were no other kinds of rocks in the field that day.
  • D. Gigi did not collect any rocks other than quartz that day.
  • E. Gigi did not see any rocks other than quartz that day.
Show Answer for Question 1
Answer: D. Gigi did not collect any rocks other than quartz that day.
The statement says that every rock Gigi collected was quartz.

Therefore, she did not collect any non-quartz rocks. The information does not prove that she saw only quartz or that no other rocks were present.

2. A café raised the price of one drink, and sales of that drink fell during the following week. The owner concludes that any price increase will always reduce sales. What is the main flaw in the reasoning?

  • A. It assumes that the café never changes its menu.
  • B. It draws a universal causal conclusion from one limited observation.
  • C. It proves that lower prices always increase sales.
  • D. It ignores the cost of producing the drink.
  • E. It shows that price and sales are unrelated.
Show Answer for Question 2
Answer: B. It draws a universal causal conclusion from one limited observation.
The owner relies on one product and one week of sales data.

Other factors may have affected sales, and one example is not enough to establish that every price increase will always produce the same result.

3. A city reports that bicycle-theft reports doubled after it introduced an online reporting form. Which information would best clarify whether bicycle theft itself actually increased?

  • A. The number of independently verified theft incidents before and after the form was introduced
  • B. The number of residents who own bicycles
  • C. The most common colors of the stolen bicycles
  • D. The cost of building the online reporting form
  • E. The hours during which the police station is open
Show Answer for Question 3
Answer: A. The number of independently verified theft incidents before and after the form was introduced
An increase in reports may reflect easier reporting rather than an increase in the underlying event.

Comparing independently verified incidents would help distinguish increased reporting from increased theft.

4. A project director says that Maya understands the technical system better than anyone else, while Luis is especially skilled at communicating with clients. The director believes they can lead the project successfully together. Which assumption does this belief rely on?

  • A. Technical knowledge is the only skill needed to lead the project.
  • B. Technical knowledge and client communication are both useful to successful leadership.
  • C. The project is too large for one person to understand.
  • D. Client communication is more important than technical knowledge.
  • E. Maya and Luis have identical leadership styles.
Show Answer for Question 4
Answer: B. Technical knowledge and client communication are both useful to successful leadership.
The director identifies one relevant strength in each person and concludes that the pair can lead successfully.

That conclusion assumes both technical knowledge and client communication contribute to successful project leadership.

5. Route 8 has made Jordan late for work every weekday this month. Jordan will take Route 8 tomorrow and concludes that it will make him late again. Which assumption does this prediction rely on?

  • A. Every bus route in the city is late.
  • B. Route 8 will have the same driver tomorrow.
  • C. The conditions that produced the earlier delays will continue tomorrow.
  • D. Jordan has no other way to reach work.
  • E. Jordan dislikes riding the bus.
Show Answer for Question 5
Answer: C. The conditions that produced the earlier delays will continue tomorrow.
Jordan uses a repeated past pattern to predict what will happen tomorrow.

The prediction relies on the assumption that the relevant conditions causing the delays will remain substantially the same.

6. Free enterprise is characterized by competition rather than a single provider within an industry. In some areas, consumers can purchase electric service only from ABC Power Company. Which conclusion follows?

  • A. A monopoly means having no competitors anywhere in the country.
  • B. ABC Power Company exemplifies competition in every area.
  • C. ABC Power Company has no employees who compete with one another.
  • D. ABC Power Company has a monopoly in some areas.
  • E. ABC Power Company must be publicly owned.
Show Answer for Question 6
Answer: D. ABC Power Company has a monopoly in some areas.
Consumers in the specified areas have only one provider of electric service.

A market with one available provider is a monopoly in that market.

7. A board member says, “The consultant’s plan is reliable because the consultant is trustworthy. We know the consultant is trustworthy because the plan is reliable.” What flaw does this argument contain?

  • A. Appeal to popularity
  • B. Circular reasoning
  • C. False dilemma
  • D. Appeal to an irrelevant authority
  • E. Slippery-slope reasoning
Show Answer for Question 7
Answer: B. Circular reasoning
The plan’s reliability is supported only by the consultant’s trustworthiness, while the consultant’s trustworthiness is supported only by the plan’s reliability.

Each claim depends on the other, so the argument never provides independent evidence for either claim.

8. A teacher asks each student to write a short story connected to the student’s everyday life. One student wants to write about the main character from a favorite movie. Which is the strongest logical objection?

  • A. A fictional movie character is unlikely to reflect the student’s own everyday life.
  • B. Using the same writing method can produce stories of different quality.
  • C. Using any movie character automatically violates copyright law.
  • D. Self-reflection is required for every original short story.
  • E. Instructional themes are always more important than popular characters.
Show Answer for Question 8
Answer: A. A fictional movie character is unlikely to reflect the student’s own everyday life.
The assignment specifically requires a connection to the student’s everyday life.

A story centered on a favorite movie character may be interesting, but it is less likely to satisfy that stated requirement.

9. A store-brand sparkling water costs half as much as a premium imported brand, and an advertisement claims that the two taste the same. It suggests serving the store brand in plain glasses if guests should not know which brand was purchased. What assumption is built into the advertisement?

  • A. Most sparkling water is imported.
  • B. Some guests may judge the drink by its brand or origin rather than taste alone.
  • C. Imported water is always more expensive because of taxes.
  • D. Store-brand and imported water must taste different.
  • E. Sparkling water tastes better in plain glasses.
Show Answer for Question 9
Answer: B. Some guests may judge the drink by its brand or origin rather than taste alone.
The advertisement claims the products taste the same but still recommends hiding the brand.

That recommendation assumes some guests may react differently once they see the label or learn the product’s origin.

10. All reptiles have scales. All snakes are reptiles. Therefore, all snakes have scales. What is the basis of this argument?

  • A. Inductive reasoning
  • B. Special knowledge
  • C. A logical syllogism
  • D. Ambiguous terminology
  • E. An unsupported generalization
Show Answer for Question 10
Answer: C. A logical syllogism
The argument applies a general rule to a subgroup.

Its structure is: all members of Group A have Trait C; all members of Group B belong to Group A; therefore, all members of Group B have Trait C.

How to Use These Questions

Identify the task before evaluating the choices. Determine whether the question asks for a conclusion, an assumption, a flaw, clarifying evidence, or the structure of an argument.

Use only the information supplied. A choice can be believable in real life and still be unsupported by the argument. Prefer the answer that follows most directly and requires the fewest extra assumptions.
