Matching Exercise 1: Cultivars and What They Did
Timestamp Reference: 7:29 – 14:37
Type: Species and cultivar identification
Instructions: Match each cultivar in Column A with what the speakers reported about it in Column B. Two items in Column B describe other plants named in the segment and do not match anything in Column A.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | Zinderellas | a) The highest cull percentage of the zinnias trialed | |
| 2 | Benary’s Giants | b) Larger flowers, fewer stems per square foot, high quality | |
| 3 | Agaves | c) Added for a different flower head type, the cactus flower type | |
| 4 | Queeny Limes | d) Must be cut at peak for best color or it looks dirty and dingy | |
| 5 | Sunday Green | e) Reliably long, thin stems | |
| 6 | Sunday Orange | f) Beautiful bloom, but stem standards not as comparable | |
| 7 | Flamingo Feather | g) A wheat type filler with very long stems and a reliable re-bloom | |
| 8 | Pampas Plume | h) Good for quality and versatility | |
| 9 | Kurume | i) An older cultivar with a smaller coxcomb form, variable in shape | |
| j) An annual panicum grass used for foliage and filler | |||
| k) A light filler that can be time consuming to harvest |
Answer Key:
1 → a, 2 → b, 3 → c, 4 → d, 5 → e, 6 → f, 7 → g, 8 → h, 9 → i

| k (distractor) | 383 | 29:01 – 29:10, gomphrena | Scott |
Build note. This is the exercise segment 02 could not build. All nine cultivar names were resolved against the recording in sweep 2 at the end of Session A, before any derived file existed, so they were available here from the start. Kurume in particular was a [VERIFY] marker rendered two different ways by the engines and named by both speakers three minutes apart.
Matching Exercise 2: Fertility and Trial Design
Timestamp Reference: 4:54 – 7:19
Type: Item to category
Instructions: Match each item in Column A with the correct value or source in Column B. Two items in Column B are values the speakers gave for something else and do not match anything in Column A.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | The low fertility rate | a) One pound of nitrogen per thousand square feet | |
| 2 | The fertilizer analysis used | b) 20-10-20 | |
| 3 | How the nutrients were delivered | c) A Dosatron system | |
| 4 | Source of the three-category fertility framework | d) The University of Maryland | |
| 5 | Year one comparison | e) Low versus medium | |
| 6 | Year two comparison | f) Low versus high | |
| 7 | The current year’s design | g) A no-fertility control plus low, medium, and high | |
| h) Three pounds of nitrogen | |||
| i) The Center for Profitable Agriculture |
Answer Key:
1 → a, 2 → b, 3 → c, 4 → d, 5 → e, 6 → f, 7 → g
Unmatched distractors: h and i

| 3 → c | 97 | 7:13 – 7:19 | Scott |
| 4 → d | 84 to 85 | 6:16 – 6:29 | Scott |
| 5 → e | 88 | 6:38 – 6:41 | Scott |
| 6 → f | 90 | 6:53 – 6:57 | Scott |
| 7 → g | 91, 94 to 95 | 6:57 – 7:10 | Scott |
| h (distractor) | 87 | 6:34 – 6:38, the high rate, not the low one | Scott |
| i (distractor) | 26 | 1:50 – 1:59, the source of the first grant, not the fertility framework | Scott |
Build note. Distractor h is deliberately the correct value for a different row. A student who has the fertility ladder straight will place it nowhere; a student guessing from the numbers alone will put it on row 1. See Build Note 1 in the quiz file on the units Scott uses in block 87.
Matching Exercise 3: Results and Their Causes
Timestamp Reference: 5:27 – 19:18
Type: Item to category
Instructions: Match each observation in Column A with the cause the speakers gave for it in Column B. Two items in Column B are causes they gave for something else and do not match anything in Column A.
| # | Column A | Column B | |
|---|---|---|---|
| 1 | The 2024 Jackson celosia data was thrown out | a) Planted too early from root bound transplants, with cool nights inducing early flowering | |
| 2 | The 2025 Jackson celosia data was thrown out | b) Off-target herbicide from a neighboring row crop plot | |
| 3 | The dip in the Queeny Lime Orange numbers | c) A septic drainage field problem and a plot move in year two | |
| 4 | Jackson zinnia counts below Knoxville’s | d) Oversized stems cut early on, plus newly prepared ground against established organic farm soil | |
| 5 | Cultivar numbers were cut back after year one | e) The volume of data overwhelmed the team and the few people they had hired | |
| 6 | Unusually high first-succession sunflower counts | f) A moist spring, plants branching after the first cut, and branched stems above pencil diameter counted as marketable | |
| 7 | Petal damage on sunflowers | g) It appeared primarily on the lighter colored flowers | |
| h) Fasciation producing a stem too thick for the bouquet | |||
| i) Stems cut before they felt woody, wilting past reviving |
Answer Key:
1 → a, 2 → b, 3 → c, 4 → d, 5 → e, 6 → f, 7 → g
Unmatched distractors: h and i

Deployment Notes
All three exercises come from the segment alone. No outside horticultural knowledge is needed and none will help; several distractors are correct statements about a different plant or a different year, which is exactly what a student working from general knowledge will fall for.
Exercise 1 is the longest at nine pairs. If Moodle rendering gets unwieldy, split it into a zinnia set of four and a celosia set of five rather than dropping pairs, since the cultivar names are the part of this segment a grower is most likely to write down.
Scaling. Three exercises for 30:30, against four for segment 02’s 16:37. Fewer exercises and more pairs, because this talk concentrates its matchable content in cultivars, rates, and causes rather than spreading it across resources and organizations.
