A hole is an opening on (something), and a TUNNEL is an end that leads to a hole that leads to another hole and to another end. Therefore, it has zero holes, but one (very small) tunnel.
It contains one hole. While it appears to have two holes, if both are closed, you get a hollow sphere, which has -1 hole.
A regular straw has zero holes. The central cavity, through which beverages flow, is not part of the straw, and hence it's endpoints are not holes in the straw.
I can't even understand the thinking that produces 2.
What about zero? If you start with a flat sheet of paper, it has zero holes, loop it around on itself, does that creat a hole?
It's just a flat plane with no holes curved around on itself.
I thought one hole intuitively, then I started thinking... what about those y shaped straws or medical hoses that split.... one hole? Two holes? Three?
Define a "hole".
Hopefully none, it won't work well if there are holes.
Physically or Metaphysically?
One common definition of a hole defines a hole specifically as the opening. If the definition applies only to the opening, this implies that the hole exists on a 2-dimensional plane. Despite the fact that the openings are connected along a tunnel, we don't care about the structure of a hole beyond the 'opening', we can ignore everything else. If we continue on that path, there are 2 visible holes on a straw.
I can't wait for Super AI to help humankind resolve these existential issues once and for all.
