How would the Children of Israel respond?

I see Belle Liu posing this challenge a lot recently. She asks her Muslim interlocutor to read Qur’an 17:101 which it says “We surely gave Moses nine clear signs. ˹You, O Prophet, can˺ ask the Children of Israel”. She then asks them to resolve the problem – the Qur’an says that there were nine signs in the Qur’an, yet the Torah read by the Jews says that there were ten.

I have yet to see any substantive response to this challenge. If anyone comes across one (or has a solution) please leave a comment.
