• Only the textbook is needed
• Both resources will be useful for the exam
• The lab manual is optional
• The final exam is cancelled

Q3The professor states: ‘Keynesian economics emerged as a RESPONSE to the Great Depression.’ The word ‘response’ indicates that Keynesian economics:

• Caused the Great Depression
• Was developed BECAUSE of the Great Depression
• Existed before the Great Depression
• Is unrelated to economic downturns

Q4In a campus conversation, the student says: ‘I’m really on the fence about switching majors.’ ‘On the fence’ means:

• Physically near a fence
• Undecided
• Strongly opposed
• Enthusiastically supportive

Q5A professor explains: ‘The control group received no treatment — this is crucial because without it, we can’t isolate the variable.’ Why is the control group important?

• It receives the experimental treatment
• It allows researchers to determine what caused the observed effect
• It eliminates the need for an experiment
• It always produces better results

Q6The professor says: ‘Now, I don’t want to oversimplify this, but at its core, natural selection is about differential reproduction.’ The phrase ‘at its core’ means:

• Inside the Earth’s core
• Fundamentally
• In a complicated way

• That 6% efficiency is adequate
• That solar technology peaked in the 1950s

Q9In a conversation, a student asks about a late assignment. The professor says: ‘I can make an exception this once, but don’t make it a habit.’ The professor is:

• Refusing to accept the late work
• Accepting the late work with a clear warning not to repeat it
• Encouraging the student to submit late regularly
• Changing the assignment deadline for all students

Q10The professor says: ‘What’s interesting about the double-slit experiment is that observation itself changes the outcome.’ This implies:

• Scientists should never observe experiments
• The act of measuring can alter quantum phenomena
• Double slits always produce the same result
• Observation has no effect on physical systems

Q11A teaching assistant says: ‘The study guide covers chapters 1 through 8, but if I were you, I’d pay extra attention to chapters 5 and 6.’ What is the TA implying?

• Chapters 5 and 6 are less important
• Chapters 5 and 6 are likely emphasized on the exam
• Only chapters 5 and 6 will be tested
• The study guide is inaccurate

Q12The professor explains: ‘Correlation does not imply causation. Just because ice cream sales and drowning rates both rise in summer doesn’t mean ice cream causes drowning.’ The example illustrates:

• That ice cream is dangerous
• A confounding variable (summer heat) drives both trends independently
• That statistics are always misleading
• Causation always implies correlation

Q13A professor says: ‘Let me play devil’s advocate here.’ This means the professor will:

• Argue a position they may not personally believe to stimulate discussion
• Share their strongest personal opinion
• End the discussion
• Assign homework

Q14The professor states: ‘Mitochondrial DNA is inherited exclusively from the mother.’ If a mitochondrial mutation is found in a person:

• It came from the father
• It was inherited through the maternal line
• It appeared spontaneously with no inheritance
• It came equally from both parents

Q15A student in office hours says: ‘I’m drowning in assignments.’ The student means:

• The student is literally underwater
• The student feels overwhelmed by the workload
• The student has finished all assignments
• The student enjoys the assignments

Q16The professor says: ‘The French Revolution is often oversimplified. It wasn’t just about liberty — economic collapse, famine, and class resentment ALL played roles.’ The professor’s main point is:

• The revolution was only about liberty
• Multiple interconnected factors caused the revolution
• Economic factors were unimportant
• The revolution is easy to understand

Q17In a lecture, the professor pauses and says: ‘Now this is going to be on the exam, so write this down.’ Why does the professor say this?

• To end the lecture early
• To signal critical exam-relevant information
• To discourage note-taking
• To change the topic

Q18The professor explains: ‘Cognitive load theory suggests that working memory has limited capacity — roughly 7 items, plus or minus 2.’ What is a practical implication?

• People can remember unlimited information
• Instructional materials should break information into small chunks
• Memory capacity is always exactly 7
• Working memory cannot be improved

Q19A student says: ‘I went to the writing center and the tutor really helped me see the forest for the trees.’ This idiom means:

• The tutor took the student to a forest
• The tutor helped the student see the overall picture instead of getting lost in details
• The student’s essay was about ecology
• The tutor was unhelpful

Q20The professor says: ‘The half-life of carbon-14 is approximately 5,730 years, which makes it ideal for dating organic materials up to about 50,000 years old.’ Why is there an upper limit?

• Carbon-14 is too expensive after 50,000 years
• After many half-lives, too little carbon-14 remains to measure accurately
• Carbon-14 disappears completely after 50,000 years
• Scientists haven’t tried dating older materials

Q21In a campus conversation, the advisor says: ‘Between you and me, Professor Chen’s section is the way to go.’ The advisor is:

• Making a formal recommendation
• Sharing an informal, slightly confidential opinion that Professor Chen’s section is better
• Criticizing Professor Chen
• Assigning the student to Professor Chen’s section

• More people means more potential helpers, yet each person is less likely to act
• Fewer people always help
• The bystander effect doesn’t exist
• People in groups are always helpful

Q23A professor says: ‘Don’t put all your eggs in one basket when choosing research sources.’ This means:

• Bring eggs to class
• Use diverse, multiple sources rather than relying on a single one
• Only use one source
• Avoid doing research

• Move forward to a new topic
• End the lecture

Q28In a conversation about internships, a career counselor says: ‘Your GPA opens doors, but your interview skills close the deal.’ This means:

• GPA is unimportant
• GPA gets you opportunities, but strong interviews secure the position
• Only interviews matter
• GPA guarantees a job

Q29The professor states: ‘Entropy in a closed system always increases — this is the second law of thermodynamics, and it’s why perpetual motion machines are impossible.’ Perpetual motion is impossible because:

• Engineers lack skill
• Energy is always lost to entropy (disorder/heat), so no machine can run forever without energy input
• Machines are too heavy
• The first law prevents it

Q30After explaining a complex topic, the professor says: ‘So in a nutshell…’ This phrase signals:

• A new, unrelated topic
• A brief summary of what was just explained
• A question for students
• The end of the course
