A: Affirmative = Your dog is barking.
Interrogative = Is your dog barking?

"Ought we ride together to the fair?"
"Should we ride together to the fair?"

A: Here's the format to do this.

A: It depends on what you are trying to ask.

"The more you learn, the less you know"? Is like if you're confused

A: × Couldn't it be that important ?
✓ It's not grammatically incorrect, but I've never heard anyone say it, and I think it would confuse people.

A: Use to is correct for questions (interrogative) and negatives.

You would say “Did you use to play baseball?”

When I answer you, I would say “Yes, I used to play baseball”

An example of a negative: I didn’t use to like broccoli, but I enjoy eating it now

The problem for English speakers is “used to” and “use to” sound exactly the same when spoken!

A: These are hard to answer with a straight yes or no. I would say, “No, none at all” or “yes, that’s right”

With a straight yes or no, I would pick “no,” but with the possibility that someone might misunderstand me.

A: "May" is not intrusive. "May" is a polite word used in formal conversation. It basically means "can" except it is more formal (and "can" has other meanings). "May I help you?" "Can I help you?" They have the same meaning, except may is more polite. However, "may" is sometimes used in asking for permission and sometimes is just a polite way of saying "do you want."

There's a joke about old-fashioned teachers who want to emphasize the difference between "may" and "can." A student asks to go the bathroom in class by saying "Can I go to the bathroom?" The teacher says "I don't know, CAN you?" The student is supposed to say "may" because it's more polite, and with "can" it could mean "do I have the ability to go the bathroom?" The student wants to know "do I have permission" to go the bathroom."

"May" doesn't work with the taking a picture example because it sounds like you are taking the picture for your own reasons. For example: "I'm writing a newspaper article about libraries. May I take a picture of you?" In this case, the sentence is fine. "Do I have permission to take a picture of you?"

"May I leave the table?" - A polite thing a child might ask if he was eating dinner with visiting family members and he was finished eating. It is used to ask for permission.

"May I use the computer?" - This is asking for permission. It is not the same as "Do you want me to use the computer?"

"May I help you?" "You may. Can you clean these plates?" This is more offering help than asking for permission.
"Do you want me to help you?" "Sure, can you clean these plates?"
--These are both totally acceptable and normal, "may" is just extra polite.

"May I give you some recommendations?" You could also say "Do you want me to give you some recommendations?" or "Would you like some recommendations?" These are all polite and have the same meaning. "May" might be considered extra polite. It is not asking for permission here, it is just a polite way of saying "do you want _____."

A: If you needed direct questions for the exact sentence 'There used to be a big casino', you could say:
- Was there a casino here?
- What used to be here?

If you needed indirect questions (example: a tour guide explaining to tourists about the casino), you could use:
- What is interesting about this place?
- What happened to this building?

The indirect questions are a little bit more natural than the direct questions though.
