## Complete first source

A fictional display committee is comparing two assigned growing-position arrangements, A and B. Each group has six initially labelled bean seedlings, with a supplied starting group mean height of 18 mm. Every final mean includes all six recorded labelled heights, including stems not marked alive; no height is missing. The alive-at-check count is separate. The plan specifies the same seed variety/stage, pots, mix, water schedule and check time; actual temperature, light, moisture and adherence are unrecorded. These constructed records are not a controlled causal finding, actual community consultation, plant care prescription or permission to move/alter living things.

Both requirements apply: **mean height increase at least 10 mm over eight days AND at least 4 of the original six alive at Day 8**. Do not combine A's measure with B's measure to invent an option. If neither meets both, say neither and ask for a reviewed next check.

| First cohort, Day 8 | Starting mean (mm) | Final mean (mm) | Alive at check | Original sample |
| --- | ---: | ---: | ---: | ---: |
| A | 18 | 29 | 4 | 6 |
| B | 18 | 28 | 5 | 6 |

**First reader:** the fictional display coordinator, using both requirements above. If more than one option qualifies, prioritise greater recorded mean height increase. Equal priority measures permit a stated tie/defer with a reason. No result for any new cohort, longer period or different species is available.

## Your first job

1. Calculate A's and B's mean height increases from the start to Day 8, with mm and eight-day period. State each alive count with its original sample and check time.
2. Make a two-requirement table for each option. Choose A, B, both/tie or neither under the first reader's complete rule; explain with two exact source details.
3. Explain how the growth/survival knowledge informs this **fictional proposed decision**, identify one condition/method limit and give a specific next evidence question before a real decision. A recommendation is not permission, observed impact, consultation or a conducted investigation.

Use any communication/access mode; an adult may read exact directions or record exact words. First response is individual and preserved before later information.
