|---|---|---|---|---|
| 1 | Which term best matches this description? Six-week timeline, available materials, space, and safety. | (D) feasibility. | 1 | L3.1 · CED Skill 4.A, 4.B, 7.A (no CED topic claimed) |
| 2 | Which term best matches this description? High salt outside the seed makes water uptake difficult, slowing or preventing germination. | (A) osmosis. | 1 | L3.2 · CED Topic 2.4, 5.5; LO ERT-2.F, EIN-2.E, EIN-2.F; Skill 4.C, 4.D, 5.A, 5.B |
| 3 | Choose the word or phrase that best completes the sentence: Each organism has a ________. Salt from irrigation can push crops out of that range, which is why salinization threatens desert agriculture. | (D) tolerance range. | 1 | L3.2 · CED Topic 2.4, 5.5; LO ERT-2.F, EIN-2.E, EIN-2.F; Skill 4.C, 4.D, 5.A, 5.B |
| 4 | Average soil moisture under mulch changed from 21% to 48% over one month. What was the percent change? | (D) +129%. Percent change = (new − old) ÷ old × 100 = (48 − 21) ÷ 21 × 100. | 1 | L3.1 · CED Skill 4.A, 4.B, 7.A; item skill 6.B (no CED topic claimed) |
