Why can just mean explain something that is unexpected. Which you did with the history lesson. It doesn't have to answer causality.

I would never do that to a French Fry.

At least the other fast food places don't have names like "Ben &Jerry" or "Baskin Robbins"

Wow

Not necessarily. It could be "Why does Dairy Queen sell food (unsaid part: when I expect it to only sell ice cream?")

A: because it used to only sell ice cream in the past.

It's the fast way of saying emergency brake, aka hand brake.

Looking at the tach is so useful through. You can learn how your car can go into gear at different speeds depending on if you're going uphill, downhill, or flat.

I disagree, I think it's better to use the e-brake to hold the car on the slope while you're engaging first gear. And when you're in gear you lower the e-brake.

Historic facts can be an answer.

How long have they been a fast food store? I thought they were an ice cream shop

Thanks for the actual answer!

That makes too much sense :/
