# C14 · A question bigger than its data

## Boundary

Collected water is not a universal soil-quality score.

## Complete source

Complete original fictional garden card, not local soil data. In one supplied trial, samples P and Q use the same described spoon size, each receives20 mL water, and the same filter setup and2-minute collection window are used. The labelled collected-water entries are P4 mL and Q9 mL. A visitor asks which soil grows the tallest tomatoes. No plant-growth, soil-quality, organism-count or drinking-water entries exist; no real child conducted this trial.

## Id

C14

## Invitation

Give a useful response that shows both a supported comparison and missing evidence.

## Next try

Propose a specific separate growth question and suitable longer evidence; no plant result is invented.

## Ordinary possible response

In this supplied single trial, P collected4 mL and Q9 mL, so P’s recorded amount is5 mL less under the stated setup. These are collected-water outputs, not tomato heights. I cannot rank tomato growth from this record.
