1. What does a 'variant' refer to in the context of consumer genetic testing?

   1. A method for treating genetic diseases
   2. A change in the DNA sequence that may or may not affect health
   3. A guaranteed outcome of a genetic condition
   4. A type of medical diagnosis

2. Why might a risk percentage from a consumer genetic test appear more concerning than it actually is?

   1. The test includes results from relatives that inflate the risk
   2. The test intentionally exaggerates to sell supplements
   3. The percentage often represents population-level risk rather than individual certainty
   4. The laboratory processing errors inflate all percentages

3. What is 'penetrance' in genetic testing?

   1. The likelihood that a variant will actually cause disease in a person who has it
   2. The process of reading genetic code
   3. The amount of DNA in a cell
   4. The percentage of people who take a genetic test

4. A friend gets a 23andMe result showing a 40% increased risk for a certain condition. They are upset and think they will definitely get the disease. What is the most accurate response?

   1. They should immediately start preventive medication
   2. The percentage represents population-level risk and doesn't predict their personal future
   3. The result likely means they have the disease but it hasn't manifested yet
   4. They should ignore the results because genetic testing is unreliable

5. What is a recommended way to use AI when reviewing genetic test results?

   1. Ask AI to diagnose a medical condition based on the results
   2. Ask AI to recommend specific vitamins to counteract genetic risks
   3. Ask AI to explain whether a result represents meaningful risk or normal variation
   4. Ask AI to determine which ancestors contributed to each variant

6. A consumer genetic test shows you have a variant linked to a certain disease, but you have no family history of that disease. What might this indicate?

   1. The test is definitely wrong because family history is always accurate
   2. The variant may have low penetrance or the disease may not develop even with the variant
   3. You were adopted and don't know your biological family
   4. The laboratory mixed up your sample with someone else's

7. What does it mean when the lesson states that genetic tests show 'possibilities, not your future'?

   1. Genetic tests only reveal what has already happened
   2. Genetic tests indicate statistical probabilities, not certain outcomes
   3. Genetic tests are completely random and meaningless
   4. Genetic tests predict exactly what will happen to you

8. What does the lesson advise asking AI to remind you about when interpreting genetic test results?

   1. That 23andMe results are not a medical diagnosis
   2. The specific treatments available for each variant
   3. The exact date you will develop any condition found
   4. The names of all your biological relatives

9. What is 'background noise' in the context of genetic test results?

   1. Marketing material included with test results
   2. Statistical variation that doesn't indicate meaningful increased risk
   3. Information about your ancestry background
   4. Errors in the laboratory testing process

10. A student receives a genetic test result showing a 2% increased risk for a condition. They want to know if they should worry. What is the best interpretation?

    1. They should immediately schedule surgery to prevent the condition
    2. The test is useless because the number is so small
    3. They have a 2% chance of getting the condition, meaning it's very unlikely
    4. They will definitely get the condition

11. Why can't consumer genetic tests like 23andMe replace a visit to the doctor for diagnosis?

    1. They are illegal in most countries
    2. They only work for rare diseases
    3. They are too expensive for most people
    4. They analyze different genetic markers than clinical tests and are not diagnostic tools

12. What should you do if a genetic test result from a consumer service scares you?

    1. See a genetic counselor who can provide professional interpretation
    2. Ignore it completely and pretend you never took the test
    3. Buy over-the-counter supplements marketed for genetic health
    4. Share it on social media to get opinions from strangers

13. Why might someone 'spiral' after seeing their genetic test results?

    1. Because genetic tests are always accurate predictors of future disease
    2. Because percentages and technical language look scary without context, making everything seem like a health emergency
    3. Because the results are publicly shared without consent
    4. Because the test results are intentionally designed to cause anxiety

14. What does it mean when a variant is described as having 'low penetrance'?

    1. The variant is very rare in the population
    2. The variant is always passed down from parents
    3. Most people with the variant will never develop the associated condition
    4. The variant can only be found in children

15. How can AI help distinguish between meaningful results and background noise in genetic testing?

    1. AI automatically deletes false results from the test
    2. AI can explain the difference between significant variants and common variation that has little health impact
    3. AI can guarantee which results are accurate
    4. AI cannot help with this task
