20 questions. Answer them in any order, then submit to see your score and every explanation.

  1. The argument above depends on which one of the following assumptions?
  2. A university administrator argues that requiring first-year students to attend a study-skills workshop improved academic performance. She notes that the average GPA for first-year students rose from 2.9 to 3.1 in the semester after the workshop became mandatory. Attendance records show that nearly all first-year students completed the workshop, and academic advisors reported that students asked more detailed questions about time management afterward. The administrator concludes that the workshop caused the GPA increase and recommends making similar workshops mandatory for all undergraduates to raise GPAs across the university. Which one of the following, if true, most strengthens the argument?
  3. A hospital administrator observes that units with mandatory handoff checklists have fewer medication errors than units without them. The cardiology unit adopted a mandatory checklist last month, and its medication errors have declined. Fewer medication errors lead to fewer patient complications, and fewer complications improve the unit's quality rating. Therefore, adopting the mandatory handoff checklist will improve the cardiology unit's quality rating. Which one of the following, if assumed, allows the conclusion to be properly drawn?
  4. Passage: A nutrition blogger claims that a particular brand of granola is "healthy" because it contains whole grains and has no added sugar. Foods that contain whole grains and avoid added sugar generally support better heart health than highly refined, sugary foods. Therefore, this granola is a healthy breakfast choice for most people. Since healthy breakfast choices help people maintain energy throughout the morning, recommending this granola will help readers feel more energetic at work. Which one of the following assumptions is required by the argument?
  5. Car use did not fall after bike lanes were added. The mayor calls this a failure. Which, if true, most weakens?
  6. The statements above most strongly support which of the following?
  7. A principal argues that whenever a school enforces a strict phone policy, classroom distractions decrease, and when distractions decrease, grades improve. The principal notes that grades improved this term. Therefore, the principal concludes that the school must have enforced a strict phone policy. Since the district did not require any such policy, the principal concludes that the school's administrators must have been more decisive than administrators at other schools. The pattern of reasoning in the argument above is most similar to that in which one of the following?
  8. The reasoning in the economist's argument is best described as which one of the following?
  9. A homeowner association president argues that replacing the neighborhood's old playground equipment will reduce injuries. She points out that in the month after a nearby neighborhood installed new equipment, its reported playground injuries dropped. Since newer equipment meets updated safety standards, the president concludes that installing new equipment in her neighborhood will lead to fewer injuries among local children. Which one of the following, if true, most seriously weakens the argument?
  10. Which one of the following, if true, casts the most doubt on the conclusion above?
  11. A grant agency states this principle for funding community projects: A proposal should be funded only if it (1) includes a detailed budget and (2) demonstrates measurable outcomes that can be evaluated within one year. If either element is missing, the proposal should not be funded, even if the project seems beneficial. The agency uses this principle to decide which proposals to support. Which one of the following most closely conforms to the principle stated above?
  12. A manager claims that the company should replace its current training program with a new online module. Last year, departments that voluntarily used the online module reported fewer minor safety incidents than departments that did not. The manager assumes that the module caused the difference. Yet those same departments also had the most experienced supervisors, who routinely enforce safety rules. Therefore, adopting the online module companywide will reduce minor safety incidents. The claim that the departments that voluntarily used the online module also had the most experienced supervisors plays which one of the following roles in the argument?
  13. A homeowner argues that installing a smart thermostat will lower her energy bills. Her current thermostat is manual, and she often forgets to turn the heat down before leaving for work. Smart thermostats can automatically reduce heating when no one is home, and her utility charges higher rates during peak hours. Even if the device costs money upfront, the monthly savings will eventually exceed that cost. Therefore, installing a smart thermostat will lower her energy bills overall. The statement that she often forgets to turn the heat down before leaving for work plays which one of the following roles in the argument?
  14. A: Coffee drinkers live longer, so coffee helps. B: Healthy people choose coffee. They disagree over whether
  15. A coffee chain tested a new training program in ten stores and found that customer complaints dropped by about 20% over the next month. In those same stores, managers reported that employees began greeting customers more consistently, a behavior the training emphasized. Because consistent greetings make customers feel acknowledged, the training program is what reduced complaints. So the chain should roll out the program companywide to reduce customer complaints across all its stores. Which one of the following is an assumption on which the argument depends?
  16. According to a study, cities with extensive public transportation systems experience less traffic congestion. Thus, expanding public transportation in urban areas will alleviate traffic problems. Which one of the following assumptions is required by the argument?
  17. A librarian claims: After our library began offering a weekly children's story hour, the number of new library cards issued to families increased. Parents who attend story hour often stay afterward to browse and check out books. Since families who get library cards are more likely to read at home, story hour must be increasing children's reading. Therefore, any library that wants to raise literacy rates in its community should prioritize starting a weekly story hour program. Which one of the following, if true, casts the most doubt on the conclusion above?
  18. A recent report states that of the 200 athletes surveyed, 60% said that maintaining a balanced diet improved their performance, while 30% said that additional sleep was the key factor. If the statements above are true, which one of the following must also be true?
  19. A union representative argues that the company's new attendance policy is unfair. The policy penalizes any worker who arrives more than five minutes late, regardless of the reason. Yet the company's parking lot often fills before the shift begins, forcing some workers to park off-site and walk. Management claims workers should "plan ahead," but the company recently reduced shuttle service from the off-site lot. Therefore, the attendance policy is unfair and should be revised. The statement that the policy penalizes any worker who arrives more than five minutes late, regardless of the reason plays which one of the following roles in the argument?
  20. Which one of the following assumptions permits the conclusion above to be properly drawn?
