Ideally, two persons (one on each end a mile apart) would keep pulling the yarn until it either breaks or lifts off of the ground. The real question here is: Which would occur first?
Stipulations:
- The humans are average ...
- Normal yarn is used. (whatever that means)
- It takes place here on Earth.
- It is over even ground.
- There is no other outside force (wind, static, etc...).
*I'm sure there are a thousand stipulations I could write here and still leave things out, but I think you get what I am saying (typing)...

no i dont think so and if it didn't break would two ppl have the strength to pull the the amount of force thats involved? i doubt it.

My guess would be it would break. To do more than guess you would need to know the weight of 1 mile of yard and its tensile strength. You'd have to use catenary formulas to determine the tension necessary to lift it off the ground.
But if you work out the angles and resolve the forces you'll find that the angle is so slight over such a distance that the tension required to hold up even a small about of weight would be tremendous. (Assuming flat ground between the two people).

I'd say no. The weight of the length of yarn would most likely overcome the tensile strength of it. It would rip apart.

My best guess is that they can't pull hard enough to pick it entirely up off the ground. It would always sag to the ground in the middle.
