Where students lose marks

Questions that ask what would weaken an argument reward finding an alternative explanation, not finding a false statement. The correct answer is frequently something that could also have caused the result.

How to study it

When a question asks about strengthening or weakening, name the argument's assumption out loud first. The answer almost always attacks or supports that assumption. For graph questions, read the axis labels and units before the data — misreading units accounts for a large share of avoidable errors.

Question 1
Read the passage
During a community health meeting, a resident argued against fluoridating the local water supply. He stated: 'My grandfather drank unfluoridated water his entire life and lived to be 97 with all his original teeth. This proves that fluoride in water is completely unnecessary for dental health.' Several audience members nodded in agreement.
Which logical fallacy is present in the argument described in the passage?
AAppeal to authority — citing an unqualified expertBAnecdotal evidence — using a single personal example to dismiss scientific evidenceCStraw man — misrepresenting the opposing argumentDBandwagon — arguing something is true because many people believe it
Correct answer: B. The resident uses one person's experience (his grandfather) to make a sweeping conclusion about fluoride for an entire population. This is an anecdotal evidence fallacy — a single case cannot disprove well-established population-level scientific evidence about fluoride's dental health benefits.
- A. The grandfather is not being cited as an expert. The fallacy is using his personal experience as evidence, not his credentials.
- C. A straw man involves misrepresenting the opposing argument. The resident addresses fluoridation directly rather than distorting the pro-fluoride position.
- D. While audience members nodded, the primary argument is based on the grandfather's example, not on how many people agree.
Question 2
Which of the following would be the most credible source for a nurse researching evidence-based wound care practices?
AA social media post by a wound care nurse sharing a personal techniqueBA systematic review of wound care studies published in a peer-reviewed nursing journalCA product advertisement from a wound care supply companyDA patient's blog describing their wound healing experience
Correct answer: B. A systematic review synthesizes findings from multiple high-quality studies, providing the strongest level of evidence in the evidence hierarchy. Published in a peer-reviewed journal, it has undergone expert evaluation for scientific rigor, methodology, and accuracy.
- A. A social media post may share useful tips but lacks peer review, systematic methodology, and may not be based on research evidence.
- C. Product advertisements are inherently biased toward promoting sales. They are marketing materials, not objective research.
- D. A patient's blog provides a personal perspective but represents one individual's experience, not systematic evidence for clinical practice.
Question 3
Read the passage
A school district implemented a new lunch program that replaced processed foods with fresh fruits, vegetables, whole grains, and lean proteins. After one academic year, the district reported a 15% decrease in student visits to the school nurse for stomach complaints, a 22% reduction in afternoon behavioral referrals, and a 10-point average improvement on standardized test scores compared to the previous year. Critics noted that the district also hired additional support staff and reduced class sizes during the same period, making it difficult to attribute all improvements solely to the lunch program.
Based on the passage, which conclusion about the school lunch program is best supported by the evidence?
AThe lunch program alone is definitively responsible for all the improvementsBThe improvements may be partly due to the lunch program but other factors also changed simultaneouslyCThe lunch program had no effect on student health or performanceDReducing class sizes was the only factor that improved test scores
Correct answer: B. The passage presents positive outcomes that occurred after the lunch program was implemented, but the critics correctly note that other changes (additional staff, reduced class sizes) happened simultaneously. Without controlling for these variables, the improvements cannot be attributed solely to the lunch program, though it may have contributed.
- A. The passage explicitly notes confounding variables (additional staff, smaller classes), making it impossible to attribute all improvements to the lunch program alone.
- C. The data shows improvements in health visits, behavior, and test scores. While the lunch program may not be the sole cause, saying it had no effect ignores the correlation.
- D. The passage mentions multiple changes. Claiming one factor is solely responsible ignores the others.
Question 4
Read the passage
The American Nurses Association reports that there are approximately 4.2 million registered nurses in the United States, making nursing the largest healthcare profession. Nursing programs have become increasingly competitive, with many schools turning away qualified applicants due to limited faculty and clinical placement sites. Some healthcare leaders argue that nursing is the most important profession in healthcare because nurses spend the most time at the bedside with patients. Others contend that all healthcare professions are equally vital to patient outcomes.
Which statement from the passage represents a fact rather than an opinion?
ANursing is the most important profession in healthcareBAll healthcare professions are equally vital to patient outcomesCThere are approximately 4.2 million registered nurses in the United StatesDNursing programs should accept more students than they currently do
Correct answer: C. This is a verifiable statistic from the American Nurses Association — a specific number that can be confirmed through data. It is a factual claim, not a value judgment.
- A. The word 'most important' is an evaluative judgment that cannot be objectively measured. Different people could reasonably disagree.
- B. Whether all professions are 'equally vital' is a value judgment. The passage presents this as one perspective ('others contend'), indicating it is an opinion.
- D. This statement does not appear in the passage and would be an opinion about what should be done, not a verifiable fact.
Question 5
A student finds the following claim on a health website: 'Drinking lemon water every morning cures diabetes.' Which evaluation of this claim is most appropriate?
AThe claim is likely true because it appears on a health websiteBThe claim should be accepted because natural remedies are always effectiveCThe claim is questionable because diabetes cannot be 'cured' by a single dietary change, and the claim lacks supporting scientific evidenceDThe claim must be true because many people have shared it on social media
Correct answer: C. This claim should be evaluated critically: diabetes (especially Type 1) cannot be cured by dietary changes alone, the word 'cures' is an absolute claim unsupported by medical research, and no scientific evidence is cited. Credible health information is supported by peer-reviewed research, not unsourced website claims.
- A. Appearing on a health website does not guarantee accuracy. Many health websites publish unverified or misleading information.
- B. The statement that natural remedies are 'always effective' is itself a false generalization. Effectiveness must be demonstrated through research.
- D. Popularity on social media does not validate a health claim. Misinformation can spread widely online regardless of its accuracy.
Question 6
Read the passage
Proponents of universal healthcare coverage argue as follows: Access to healthcare is a basic human right. When people cannot afford healthcare, they delay treatment until conditions become emergencies, which increases suffering and costs more to treat. Countries with universal coverage, such as Canada and the United Kingdom, spend less per capita on healthcare while achieving comparable or better health outcomes than the United States. Therefore, implementing universal healthcare coverage in the United States would improve health outcomes while reducing overall costs.
Which of the following best describes the logical structure of the argument in the passage?
APremise → evidence → counterargument → rebuttalBPremise → supporting evidence → conclusionCAnecdote → emotional appeal → call to actionDQuestion → hypothesis → experiment → result
Correct answer: B. The argument follows a logical structure: it states a premise (healthcare is a human right), provides supporting evidence (delayed treatment costs more; other countries spend less with better outcomes), and draws a conclusion (universal coverage would improve outcomes and reduce costs).
- A. The passage does not include a counterargument or rebuttal. It presents only the proponents' argument.
- C. The passage uses logical reasoning and international comparisons, not personal stories or purely emotional appeals.
- D. This is the structure of a scientific experiment, not a policy argument. The passage does not describe a hypothesis or experiment.
Question 7
Read the passage
A hospital administrator argues that replacing experienced registered nurses with less expensive nursing assistants on medical-surgical units would reduce labor costs by 30% without affecting patient care quality. The administrator cites a single pilot study conducted at a small rural hospital showing no significant difference in patient satisfaction scores during a three-month trial period.
Which piece of evidence would most weaken the argument presented in the passage?
AA large multi-center study showing that higher RN staffing ratios are associated with significantly lower patient mortality ratesBA testimonial from a nurse who enjoyed working with nursing assistantsCData showing that the administrator's hospital has been recognized for cost efficiencyDA report showing that nursing assistants earn lower salaries than registered nurses
Correct answer: A. A large multi-center study showing that higher RN staffing improves mortality rates would directly contradict the administrator's claim that replacing RNs would not affect care quality. Stronger evidence (larger sample, multiple sites, objective outcome of mortality rather than satisfaction) would undermine the argument based on a single small pilot study.
- B. A single testimonial about enjoyment does not address care quality or patient outcomes, so it neither strengthens nor meaningfully weakens the argument.
- C. Cost efficiency recognition supports the administrator's cost-cutting approach but does not address whether replacing RNs affects patient care quality.
- D. Lower salaries for nursing assistants supports the cost reduction claim but does not address care quality, which is the disputed point.
Question 8
Read the passage
The COVID-19 pandemic resulted in more than 6.5 million deaths worldwide by the end of 2022. Vaccines were developed in record time, with the first Emergency Use Authorization granted in December 2020, less than a year after the virus was first identified. The pandemic exposed significant weaknesses in global public health infrastructure, including shortages of personal protective equipment, insufficient hospital capacity, and fragmented data reporting systems. Many public health experts believe that the world was woefully unprepared for a pandemic of this magnitude.
Which statement from the passage is an opinion rather than a fact?
AThe pandemic resulted in more than 6.5 million deaths worldwideBThe first Emergency Use Authorization was granted in December 2020CThe world was woefully unprepared for a pandemic of this magnitudeDShortages of personal protective equipment were a significant weakness
Correct answer: C. The word 'woefully' is an evaluative term expressing a judgment about the degree of unpreparedness. The phrase 'many public health experts believe' signals this as a professional opinion rather than a verifiable fact.
- A. This is a verifiable statistic from global health databases.
- B. This is a verifiable historical date that can be confirmed through public records.
- D. PPE shortages were documented and quantifiable events reported by hospitals and governments — a verifiable fact.
Question 9
A reader encounters the following headline on a news website: 'SHOCKING: Doctors Don't Want You to Know This One Simple Trick to Cure Cancer!' Which critical thinking response is most appropriate?
AClick the article immediately because it promises a cancer cureBShare the article on social media to help others before reading itCRecognize the headline as clickbait that uses sensational language and is unlikely to contain credible medical informationDAssume the article is true because it mentions doctors
Correct answer: C. This headline contains multiple red flags for unreliable health information: sensational language ('SHOCKING'), conspiracy framing ('doctors don't want you to know'), and oversimplified promises ('one simple trick to cure cancer'). Credible medical information does not use manipulative language or promise miraculous cures.
- A. Clicking sensationalist health headlines rewards clickbait publishers and exposes readers to potential misinformation.
- B. Sharing unverified health claims spreads misinformation and could lead others to make harmful health decisions.
- D. Mentioning doctors does not make a claim credible. The framing ('doctors don't want you to know') actually implies a conspiracy theory.
Question 10
Read the passage
Research consistently demonstrates a strong positive correlation between education level and health outcomes. Adults with a college degree live an average of 8-10 years longer than those without a high school diploma. Higher education is associated with lower rates of smoking, obesity, heart disease, and diabetes. Researchers attribute this relationship to several factors: higher-educated individuals tend to have better-paying jobs with health insurance, greater access to health information and resources, stronger health literacy skills, and more social capital that promotes healthy behaviors.
Based on the passage, which conclusion about the relationship between education level and health outcomes is best supported?
AEducation directly causes people to be physically healthier through the knowledge they gain in classesBEducation level is associated with better health outcomes through multiple interconnected pathways including income, access, literacy, and social factorsCPeople without college degrees cannot achieve good health outcomesDEducation level has no significant impact on how long a person lives
Correct answer: B. The passage identifies multiple pathways linking education to health: better jobs with insurance, access to information, health literacy, and social capital. This shows education influences health through interconnected socioeconomic factors, not a single direct mechanism.
- A. The passage does not claim classroom knowledge directly causes health. It identifies socioeconomic pathways (income, access, literacy) as the connecting mechanisms.
- C. The passage describes population-level correlations, not absolute rules. Individuals without degrees can still achieve good health outcomes.
- D. The passage cites an 8-10 year life expectancy difference, clearly showing a significant impact.
