I would like you to understand the main points (without having/looking at the previous text)
There’s no way of knowing whether the “you” represents a person (male/femal) or a person(s)/a group  formal/informal so I wrote: entendieran

Hola Nicole P.
You’re absolutely right, thanks for pointing this out.
Without additional context, it isn’t possible to determine whether “you” refers to a singular or plural form, or the level of formality, so your choice of “entendieran” is perfectly justified.
We’ve now added an extra hint to clarify this and guide learners more clearly toward the expected answer.
Thanks again for your helpful feedback!
Hasta pronto
Silvia
