   Marlo Island, an invented country used to practice real ideas (cards A to D). Card A, from the Marlo Statistics Office, a table of last year's export income (total $500 million): coffee beans 72 percent, fish 18 percent, fruit 10 percent. Card B, from the same office: last year a bag of coffee sold for $200; this year it sells for $140, and Marlo's farms sold the same number of bags both years. Card C, from the Marlo Coffee Growers' Association press release: "Coffee is the heart of Marlo. Prices always come back, so no change is needed." Card D, from the Statistics Office: Marlo makes almost no fuel or machines and buys them from other countries with its export income. Fish and fruit exports stayed at last year's amounts.

2. 1.

   From card A, how much of Marlo's export income came from coffee beans last year, Ari asks?

   • $360 million, found by taking 72 percent of $500 million
   • $72 million, since the table shows the number 72
   • $140 million, the price of a bag of coffee this year
   • $180 million, found by taking half of the $360 million total
3. 2.

   Card D says Marlo buys fuel and machines with its export income. Which chain follows from cards B and D, Jun asks?

   • A lower price cuts export income, so Marlo can buy fewer imports
   • Buying fewer imports lowers the coffee price, so export income falls
   • A lower coffee price also cuts the prices of fish and fruit, so the other exports earn less
   • A lower coffee price makes Marlo grow more coffee, which fixes the import problem
4. 3.

   A student says, "Card A shows Marlo's export income depends on one product." How strong is that claim, Kira asks?

   • Weak: fish and fruit together are worth more than coffee
   • Weak: three exports means Marlo is protected when one price changes
   • Strong: coffee is 72 percent of export income, far more than fish or fruit
   • Strong: card A shows coffee is also most of what Marlo earns inside the island
5. 4.

   Who wrote card C, and why might it say "no change is needed," Luz asks?

   • Marlo's fishers, who earn more when the coffee price rises
   • The Coffee Growers' Association, speaking for coffee farmers
   • A neutral team of experts, so its claim is settled fact
   • The Statistics Office, which just counts numbers and takes no side
6. 5.

   Card B shows the coffee price falling while fish and fruit exports stay the same. How might a coffee farmer and a fisher on Marlo see it, Milo asks?

   • The farmer is hurt by the lower price; the fisher may not be
   • Neither is affected, since the same number of bags were sold
   • Both lose the same share, since both sell their goods on Marlo
   • The fisher loses more, since fish is a larger share of the island's catch
7. 6.

   Suppose Marlo doubles its fruit exports and the other exports stay the same. Coffee is $360 million and the new total is $550 million. About what share is coffee now, Noah asks?

   • About 72 percent, since coffee income did not change
   • About 50 percent, since doubling one export splits income in half
   • About 65 percent, still the largest share but lower than before
   • About 79 percent, since adding fruit makes coffee more important
8. 7.

   Card C says prices always come back. Does card B support that, Pia asks?

   • Yes: a $140 price shows the price is already coming back
   • Yes: farms sold the same bags, so prices must rise again
   • No: card B shows one price fall and nothing about what comes next
   • No: a Statistics Office report cannot be used as evidence
9. 8.

   A student says, "Coffee plants regrow, so Marlo's coffee income is safe." Which reply is best, Ren asks?

   • Right: renewable crops keep a steady price
   • Right: resources that run out can lose value, but crops cannot
   • Not safe: coffee is renewable, but its price can still fall
   • Wrong: coffee is not renewable, because farmers must replant it
10. 9.

    Which source would best check card B's coffee price, Tala asks?

    • A record of coffee sale prices at the island's export port
    • A newspaper article retelling the price from the press release
    • A tourist guide that describes coffee farms on the island
    • Another statement from the growers' association, since it speaks for farmers
11. 10.

    At this year's $140 price, about how many bags would Marlo need to sell to earn last year's $360 million, and how does that compare with the 1.8 million sold, Zee asks?

    • 2.6 million more bags than last year
    • About 2.6 million bags, about 0.8 million more than last year
    • About 1.3 million bags, since a lower price means fewer bags
    • 1.8 million bags, the same as last year
