I read a similar post about it, and I understand the general rule:
I took all the apples that were in the basket. (not all the apples in the world.)
All apples have seeds. (In the world)
But I still have some doubts regarding the following case. Let's say I'm writing about a group of people having a conference in a room, and, at some point, something happens that grabs the attention of all (the) attendees.
Can I say:
All attendees turned their faces to see what was happening.
This definitely doesn't sound like all attendees in the world, but those at that conference only.
So, my questions are:
- Which is correct in this case: all the attendees or all attendees?
- Is all attendees correct (in case it is) because it is obvious from the context?
- If all the attendees is correct, do I also have to add in the same sentence that were at the conference (like the example of the apples; that were in the basket), or can I just leave it, so as to avoid repeating every time?
