1. Read this first

   Use this

   Cards A and B on a baker labor market (all made up for practice). Card A, "Bakers in one town (made up)". Written for this sheet. Table, columns Wage per hour | Bakers firms want | Bakers who offer to work: $12 | 140 | 60; $14 | 120 | 80; $16 | 100 | 100; $18 | 80 | 120; $20 | 60 | 140. Card B, "A new chain opens (made up)". Written for this sheet. Summary in our words, not a quotation: a new bakery chain opens in town. At every wage, local firms now want 40 more bakers than card A shows. The number of bakers who offer to work at each wage does not change.

2. 1.

   Jun uses cards A and B. Where does the wage settle after the chain opens?

   • At $18 with 80 bakers: the wage rises, but the higher wage leads firms to hire fewer bakers than before
   • At $18 with 120 bakers: a rise in demand lifts both the wage and the number employed
   • At $16 with 140 bakers: the wage stays where it was and firms simply hire 40 more people
   • At $20 with 100 bakers: the wage keeps rising until firms want just the 100 bakers they hired before
3. 2.

   A reader says wages rose because bakers became more willing to work. Ren checks card B. What is the verdict?

   • Supported: a higher wage always brings out more workers, so the supply of bakers must have grown
   • Not supported, because wages in a town are set by the owners of the firms and not by supply or demand
   • Not supported: card B changes only firms' demand, and the bakers offering at each wage are the same
   • Supported: more bakers are employed after the chain opens, which shows more bakers were willing to work

4. Use this

   Cards A and B on unemployment and schooling (card A is BLS data; card B is a note). Card A, "Unemployment by schooling, 2019, 2020 and 2024". Source: BLS, unemployment rate of people 25 and over by educational attainment, annual averages (series LNU04027659, LNU04027660, LNU04027689, LNU04027662), read through the BLS public data API on Nov 14, 2026. Table, columns Year | No high school diploma | High school diploma | Some college | Bachelor's degree or more: 2019 | 5.4 | 3.7 | 3.0 | 2.1; 2020 | 11.7 | 9.0 | 7.8 | 4.8; 2024 | 6.2 | 4.2 | 3.4 | 2.3. Rates are percents of the labor force. Card B, "What the rate counts". Source: BLS. Summary in our words, not a quotation: the unemployment rate is the share of people in the labor force who have no job, are available to work and have looked for work. Each figure is an average for a group, not a measure for any one person.

5. 3.

   Pia writes one claim from card A. Which claim does the table support best?

   • Unemployment rates tell how long people are out of work, so the 2020 rates show very long job searches
   • People with a bachelor's degree were rarely unemployed in 2020, since their rate was 4.8 percent
   • Finishing school causes lower unemployment, since each extra level of schooling lowers the rate on card A
   • In each year shown, the more schooling a group had, the lower its unemployment rate
6. 4.

   Zee compares the 2019 and 2020 rows of card A. Which statement compares the groups fairly?

   • The gap between the two groups stayed at 3.3 points, since both groups' rates doubled together
   • Workers without a diploma were hit twice as hard in percent terms, since their rate rose 6.3 points and the other 2.7
   • Workers without a diploma were the ones whose unemployment more than doubled, since theirs was highest in 2020
   • Both rates more than doubled, 2.2 and 2.3 times, so the hit was alike in percent though the gap in points widened

7. Use this

   Cards A and B on two jobs (all made up for practice). Card A, "Two jobs (made up)". Written for this sheet. Table, columns | Roofer | Clerk: Training needed | 6 months | 6 months; Pay per hour | $24 | $19; Chance of a serious injury in a year | 1 in 10 | 1 in 500; Hours worked in a year | 2,000 | 2,000. Card B, "Ana (made up)". Written for this sheet. Summary in our words, not a quotation: Ana can do either job. Ana would give up $12,000 a year to avoid the extra injury risk of roofing.

8. 5.

   Milo reads card A. Why does the roofer's pay exceed the clerk's even though the training is the same?

   • Roofing pays more because injury risk is low, so firms can afford to pay more for safe work
   • Fewer people will take the risky job at the clerk's wage, so roofing must pay more to fill its jobs
   • Roofing needs more training, which is why it pays more, as pay follows how long a worker trains
   • Roofers produce more value each hour than clerks, so their higher pay simply reflects a larger output
9. 6.

   A safety law cuts the roofer's injury chance to 1 in 50. Noah uses card A. What is the likely effect on roofing pay?

   • Pay falls because firms want fewer roofers, since a law makes the work less profitable
   • Pay tends to rise, since a safer job is more valuable and firms will bid more for roofers
   • Pay tends to fall toward the clerk's, since a safer job draws more people to roofing
   • Pay stays at $24, since the work itself is unchanged and pay depends on the work done and nothing else
10. 7.

    Tala reads cards A and B. Which job should Ana take, and why?

    • Clerk: its injury chance is lower, and a lower injury chance settles the choice on its own
    • Roofer: the extra pay is $12,000 a year, which is the amount Ana says is needed
    • Clerk: roofing's extra $10,000 a year is less than the $12,000 Ana would give up to avoid its risk
    • Roofer: it pays $5 more an hour, and a higher wage is the better choice for a worker

11. Use this

    Cards A and B on a bakery's hiring (all made up for practice). Card A, "A bakery's workers (made up)". Written for this sheet. Table, columns Worker hired | Extra revenue per hour that worker adds: 1st | $40; 2nd | $30; 3rd | $22; 4th | $16; 5th | $10. The ovens and space stay the same. Card B, "The wage (made up)". Written for this sheet. Summary in our words, not a quotation: the bakery pays each worker $15 an hour. Later the wage rises to $18 an hour.

12. 8.

    Luz reads cards A and B. How many workers should the bakery hire at $15 an hour?

    • Four: the 4th worker adds $16, more than the $15 wage, but the 5th adds only $10
    • Three: the 3rd worker adds $22, and the bakery should stop where extra revenue is far above the wage
    • Five: every worker adds some revenue, and any extra revenue is worth the bakery's while
    • One: the 1st worker adds the most revenue, $40, so the bakery should hire the most productive worker
13. 9.

    The wage rises to $18. Bo uses cards A and B. What happens to hiring?

    • The bakery hires none, since the wage rose by $3 and a rise that large ends the bakery's profit
    • The bakery hires four, because the 4th worker adds $16 and card A shows no fall in revenue
    • The bakery hires five: a higher wage pulls in more workers, so the bakery takes on more staff
    • The bakery hires three: the 3rd worker adds $22, above $18, but the 4th adds only $16
14. 10.

    A manager says to hire a 5th worker at $15 because four workers bring in $27 each on average. Ari tests this with card A. What is the verdict?

    • Wrong: the 5th worker adds only $10, below the $15 wage, whatever the average revenue per worker
    • Right: the 5th worker adds revenue of $10, and any added revenue helps the bakery's total
    • Right: the average worker brings in $27, which is far above the $15 wage, so more hiring pays
    • Wrong: $27 is more than the 1st worker's $40, so the manager's average cannot be correct
