Hola Benhur

Yes, that would also be correct as long as you use "e":

¡e incluso dio su opinión!

We have in the hint even = hasta; this is why "incluso" wasn't included in the answers, but it is also correct and I have just added it to the answers.

I imagine you know the reason to use "e" here, but just in case, here is the explanation.

I hope it helps.
