Inside the school’s time capsule was an envelope labeled “Letter from the first principal, 2001.” Beside it lay a repair receipt dated 2021. Some students said the receipt proved the letter was newer than its label. Others trusted the old-fashioned handwriting on the envelope.

Mina wanted to infer an explanation by connecting the clues, not simply choose a side. Could the maintenance records substantiate either claim with evidence? She requested the entry that matched the receipt.

To refute the label, they would need more than a reason to doubt it; they would need evidence showing that its claim was false. To confirm it, they would also need more than handwriting that looked old.

The archivist warned that the result might be inconclusive. They might learn something about the container without settling who wrote the letter or when. Mina placed the label, receipt, and maintenance record side by side, ready to separate those questions.
