問題文が読み解けなかったです。「感染者の増加率が前日比 20 % を上回った日を特定する(およそ 7 日間の増加率を示す)」は英語ともちょっと違い、 当日の累計数と前日の累計数の比較で20%、当日の増加数と前日の増加数の比較で20%、当日の増加率と前日の増加率で20%(統計的にはおかしい比べ方)全部試しましたがどれも違う。7日間平均というわけでもない。具体的な回答を求めるならあいまいな問題文ではなく式を示してはどうでしょう?不明確な定義を避けるために共通理解のため式を明示するのは現実の場でも正しい対応だと思います。

There can be different ways to write SQL queries which would yield the same results. Please review the output before calling it incorrect.

In my option, it is problematic that the progress checking tool provides no feedback, especially in situations where a failed query and a passed query had the same output.
