i am having a hard time knowing which preposition to use ("of the", "by the", "from the", "to the", et al) 

Not to mention which indirect object pronoun goes before the other (She gives it to him in the morning "Ella se lo da por la mañana")?

Porqué usa se puede ver muchas flores en vez de se puede ver muchas flores.  

I came across this question in the exercises.

Al profesor le gustaría que los niños ________ en voz alta

I selected the correct answer which was hablara.

However my first intuition was that the answer would be hable.

Hable wasn't one of the options however.

Would hable also be a potential correct answer for this question?

Thank you.

How in the hell is that "llegaremos"? Even with about 50 repeats I did not get that. Is she actually saying something else or how does that work? Always sounds like "digaremos" to me :-(

Fernando ___ a Luisa... In another lesson you said that when naming the person, the "le, les" cannot be omitted. I used "estuvo explicándole" but the right answer is "estuvo explicando." Why? Thanks!

When would be appropriate to use formal and informal second person?

For context, I'm planning to speak mostly with my Mexican family members, many that I'll be meeting for the first time or for the first time in many years. Most of them are older than me (I have one younger brother who speaks mostly Spanish). Would it be better to speak formally to the older family members, or informally because they're family?

Would you start formally with strangers (esp. those who are older) and then at some point be able to drop formality as you become closer to people, or as they express to you that it's okay (similar to Korean and Japanese)?
