Circle the best answer.

1. 1.

   Beside it, a chain of boxes: cause, effect, solution. A blog sees "2017 to 2019: rose 0.1 ft" and claims the aquifer has recovered. What is the flaw, Ari?

   • 0.1 ft is a huge rise for an aquifer
   • The table shows no rise at any time
   • Two years is short; since about 1950 it fell 16.5 ft
   • No flaw: a small rise shows the aquifer has fully recovered
2. 2.

   Beside it, a chain of boxes: cause, effect, solution. A claim says water levels fell in every part of the aquifer. What does the USGS table show, Bo?

   • Yes: each part fell 16.5 ft
   • Yes: the Texas part fell, so the other parts fell as well
   • Not everywhere: the South Dakota part rose 0.5 ft
   • Levels rose 44.1 ft in the Texas part
3. 3.

   Beside it, a chain of boxes: cause, effect, solution. A poster claims, "Most homes waste 50 gallons a day through leaks." Using the EPA table, what is the flaw, Esme?

   • No flaw: EPA says about 90% of homes
   • No flaw: each home leaks that much
   • EPA says homes do not leak
   • EPA says about 9% of homes, not most

4. Read this first

   Use this

   Two tables. Table 1 (EIA, US energy use in 2025), columns source, share of US energy use: petroleum, about 38%; natural gas, about 36%; coal, about 9%; renewable energy, about 9%. Table 2 (EIA, US carbon dioxide from people in 2022), columns source, share: burning fossil fuels, 93%; other sources, 7%.

5. 4.

   Using both EIA tables, which claim is supported, Jun?

   • Fossil fuel use will end in the US by 2030
   • Fossil fuels gave most of the energy but just a small part of the CO₂
   • Fossil fuels gave most US energy and most US human-caused CO₂
   • Renewable energy gave most US energy
6. 5.

   Beside it, a chain of boxes: cause, effect, solution. Using the USGS table, about how much farther did the average water level fall from 2007 to 2019, Kira?

   • About 2.5 ft
   • About 0.1 ft
   • About 16.5 ft
   • About 30.5 ft

7. USGS, High Plains aquifer

   period	average water-level change
   about 1950 to 2007	fell 14.0 ft
   about 1950 to 2019	fell 16.5 ft
   2017 to 2019	rose 0.1 ft

   USGS card: when water levels fall, wells may need deepening, pumping costs rise, and streams can get less water. Beside it, a chain of boxes: cause, effect, solution.

8. 6.

   Using the table and the USGS card, which claim is best supported, Luz?

   • Wells where levels fell may now cost more to pump
   • Each High Plains well has gone dry since about 1950
   • Pumping costs fell as the water levels fell
   • Streams gained water as the levels fell
9. 7.

   Claim: "Our town should build a solar farm." Which reasoning weighs both sides, Noah?

   • Renewable, but output varies with weather and it needs land
   • Works at night just as well as by day
   • Burns coal to make its power, so no gain
   • Renewable sunlight, so there is no downside of any kind to weigh
10. 8.

    Claim: "Our school should put in water-saving toilets." Which reasoning weighs both sides, Pia?

    • Saves water each year, but costs money and work to put in
    • Uses more water, but it costs nothing
    • Saves water each year, and it costs nothing to put them in
    • Toilets use no water, so nothing changes
11. 9.

    Ren claims, "Our school uses less water since new faucets went in." Which data would test the claim best?

    • One meter reading from the day after
    • A list of the faucets' colors
    • A survey of who likes the new faucets
    • Meter readings for many months before and after
12. 10.

    A claim says, "US energy use is moving toward renewable energy." Which data would test it best, Tala?

    • The renewable share for one single year
    • An ad for rooftop solar panels
    • EIA renewable shares for many years in a row
    • A photo of one wind turbine
