For Question 8   I answered 'trabaje' believing it to be the correct subjunctive form but it was marked incorrect and 'trabaja' was given as the correct answer.  Would you please explain.  Many thanks.

In a multiple choice question, give all possible answers. Got two correct, one wrong. Therefore all wrong?

 Since the preposition “a” as a personal “a” wouldn’t “les” also be a correct?

I will tell my son that you have called.    VS

Le dire a mi hijo que lllamaste.

In Kwiziq, there's a lesson on -ito etc and a lesson on -illo etc. I'm living in Ecuador and have traveled around Central and South America a bit, and I've heard both groups of suffixes used in what seems to be the exact same way. I guess I'm looking for a little clarity on whether they are 100% interchangeable. 

Am I correct that team -ito and team -illo mean the same thing - they make a word diminutive, softer, affectionate - and that the real difference is just in local usage? I can use either group of suffixes, and not be wrong, but one group is just more common in certain areas than the other?

My apologies if you've answered this elsewhere. I reviewed the other questions, and I did not find an answer that makes me confident that my understanding is correct.

And thanks, in advance for your help.
