Use full C18. First ask about agreement on the drawn pane; then ask about a real open ground patch outside. Child explains which supplied match answers the first and which unsupplied source the second needs. Check: an already useful pair can fail to answer a different question without becoming false. Next: C17 for the intended daily time difference.
Complete named ordinary first source
Imaginary reporter El and reporter Fen independently read the same front-view paper pane at the stated same story time. Both report the same three drawn drops. The selected question is whether their descriptions of that visible feature agree. The source provides matching view/time/feature and records no extra difference. No actual real peer comparison or live weather investigation is supplied.
Source review is complete for this two-week edition. Local suitability and classroom use still need review. Earlier candidate or pending-review words are retained in the original files; full-year coverage, translations and audio are not claimed.
