Does "Merci de bien vouloir attacher vos ceintures" have the same formal register as "Veuillez attacher vos ceintures"?  Are they both polite and formal ways of making a request?

I see several people have asked this or similar question. I’ve read one available answer and am still confused, and I continually run up against this des vs les.

Example: Men use razors to shave. = LES hommes utilisent DES rasoirs pour se raser.

It is LES hommes because it’s referring to men in general. Why is it not LES rasoirs? Isn’t it referring to razors in general?

Thank you for any help. 

Hello!

In the lesson re: 

“Use il/elle est for statements and opinions related to specific things.”

Tu aimes mon pull?  Oui, il est très beau.

My question: do you ever use il/elle est in the plural, ie., ils/elles sont, in these instances?

How would you answer: Tu aimes mes pulls?  

Would it be: Oui, ils sont beaux. If not, can you explain why?

Thank you for your help! 

The lesson says that apparaitre and naitre and derivatives use etre in the passe compose.  But in the Test, the rabit disapeared from the hat uses avoir.
