What is the Organization entity in the schema.org microformat, and is it different from LocalBusiness?

Question

HTML

In the process of studying Microdata, I discovered
that the validator does not skip “working hours” if they are written in the LocalBusiness section.
Therefore, to add office hours INSIDE the Organization, I add LocalBusiness Example
:

<div itemscope itemtype="http://schema.org/Organization">
    …
    <div itemscope itemtype="http://schema.org/LocalBusiness">
           …
          (время работы офиса)
     </div>
</div>

Hence the questions:
1. What is the entity Organization? Do organizations have an office?
2. Maybe I should make it smarter - everything in the form of LocalBusiness?
(two options: a site-online project, a site-shop with many points of issue)
3. Since the address of the organization and office are the same, the addresses on the page are duplicated. Is it bad for a search engine?
4. Am I doing the right layout by placing LocalBusiness inside an Organization?
A BIG THANK YOU to everyone who responded in advance!
