Does a straw have one hole? Is it two? jpg

(1)Is there only one or two holes in the straw?
(2)a one-way argument
(3)- If there are two straw holes, does the donut have two holes?
(4)- A straw hole is a long hole.
(5)- Those who didn’t even learn topological mathematics. (Laughs)
(6)a two-way argument
(7)- Two holes underneath the top, guys.
(8)- If there’s a door in front of the building, it’s topologically like a straw, but mathematicians say the building has two entrances, not one.
(9)The donut is short, so it feels closer to the noodles than the three-dimensional space, so it’s called one.
