Caused by: android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0

タイトルのようなエラーコードが出てしまって困っています。
文字数が足りないので自分でエラーと関係しそうなところだけ抜き出してあります。
ほかのところが原因になっている可能性がある場合は言ってください。
クイズはsqlで管理しているのですが最初quiz3までしか書いていなかったときは正常に動いていたのですが、113まで追加したところエラーが出てしまいましたそれが何かの原因になっていると思うのですが、、、

ご教授お願いします。
