Scope Note
Every term, figure, and relationship below comes from the presentation. Each
exercise carries extra items in Column B so a student cannot finish by
elimination, and each extra item is also something Stock said, placed where it
does not belong.
One trial result is deliberately absent. The crop-by-crop outcome of the
annual wool trial turns on the word at blocks 285 and 286, which Stage 1 settled
on sense rather than audio. No pair here depends on it.
Matching Exercise 1: Numbers and What They Describe
Timestamp Reference: 3:27 – 26:30 (figures drawn from across the talk)
Type: Timing-Practice / quantitative recall
Instructions: Match each figure in Column A with what Stock used it to describe. Two items in Column B are not used.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Two | a) Extra soil moisture under wool at any given time in the annual trial | |
| 2 | About 10 % | b) Water saved with wool during perennial establishment | |
| 3 | At least 5 % | c) Root zone cooling under wool in the annual trial | |
| 4 | Five to seven degrees | d) The salinity figure to use as a reference point on a compost analysis | |
| 5 | 30 % | e) Nitrogen content of raw wool | |
| 6 | 50 % | f) Elevation at the Utah State research site | |
| 7 | About 40 degrees | g) Day-to-night temperature swing in the Utah desert | |
| 8 | Five thousand feet | h) Irrigation cut a cooperating farm reached using shade | |
| i) Mineral nutrients held in the soil bank | |||
| j) Soil temperature the perennial study tried to stay below |
Answer Key:
1 → d, 2 → e, 3 → a, 4 → c, 5 → b, 6 → h, 7 → g, 8 → f
Unused distractors: i) is 14, the count of mineral nutrients (block 122, 8:26). j) is 80 degrees, the ceiling Stock names when reading the perennial temperature figure (block 292, 20:10). Both are real figures from the talk attached to no item in Column A.

Matching Exercise 2: Ground Covers and What Stock Reported
Timestamp Reference: 16:13 – 26:30
Type: Product-Practice
Instructions: Match each treatment in Column A with the result or use Stock reported for it. Two items in Column B are not used.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Wool mulch | a) About a 10 % water savings against bare soil during establishment | |
| 2 | Plastic landscape fabric | b) Tested against black plastic on dahlia to moderate root zone temperature | |
| 3 | Black plastic mulch | c) The steadiest soil temperature in the perennial figure, and 30 % water saved | |
| 4 | White plastic mulch | d) Warms the soil early in the year and holds warmth through the night swing | |
| 5 | Shade cloth | e) The untreated comparison in both the annual and the perennial wool studies | |
| 6 | Low tunnels | f) Cuts the sun load without changing air temperature; replaces tunnel plastic in summer | |
| 7 | Bare soil | g) Used for adding shade and fabric over shorter rows | |
| h) Grown as a cut flower and used for wreath making | |||
| i) Photographed in bloom at the research farm and named as an agritourism option |
Answer Key:
1 → c, 2 → a, 3 → d, 4 → b, 5 → f, 6 → g, 7 → e
Unused distractors: h) is millet (block 197, 13:28). i) is crimson clover (blocks 190–192, 13:07). Both are plants from the cover crop section rather than ground covers from the mulch section.
Source in transcript: blocks 190–192, 197, 243–246, 269, 290–293, 297–299, 374–378, 383
Matching Exercise 3: Cover Crops, Residue, and Who Said What
Timestamp Reference: 12:03 – 14:51
Type: Term-to-Definition
Instructions: Match each item in Column A with Stock’s description in Column B. Two items in Column B are not used.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | A cover crop | a) Named alongside crimson clover as gorgeous in the field | |
| 2 | Crimson clover | b) Something grown more for the soil than for ourselves | |
| 3 | Buckwheat | c) Could also serve as a cut flower and for wreath making | |
| 4 | Millet | d) Photographed at the research farm; Stock calls the planting absolutely gorgeous | |
| 5 | SARE | e) The organization Stock plugs for cover crop information | |
| 6 | Andrew McGuire | f) Get it out of the field rather than returning it to the soil | |
| 7 | Diseased crop residue | g) The factor that mattered most in the literature review Stock cites | |
| 8 | Residue management | h) Reviews cover crop and soil health research on a blog out of Washington State | |
| i) Brought Stock the question of whether wool could be used with cut flowers | |||
| j) Developed the do-it-yourself high tunnel design at Utah State |
Answer Key:
1 → b, 2 → d, 3 → a, 4 → c, 5 → e, 6 → h, 7 → f, 8 → g
Unused distractors: i) is the sheep specialist (blocks 261–264, 17:48). j) is the fruit and vegetable specialist (block 369, 25:02). Both are unnamed colleagues from other sections of the talk, so a student who guesses by “a person” cannot land on the right pair.

Verification
- All terms, figures, and relationships trace to the block numbers listed under each exercise.
- No pair depends on the two items Stage 1 settled on sense rather than audio.
- Each exercise carries two extra Column B items, all drawn from elsewhere in the same presentation.
- No item requires knowledge from outside the talk.
