Question

before snowplows were invented, travel on snow - clogged roads was a pain. in the 1840s, however, the first patents were issued for plows attached to carts pulled by horses. these early snowplows cleared roads, making it easier to travel. plows created a new issue, though. they made huge piles of snow on the sides of the road, blocking storefronts. one way to deal with this was to hire shovelers to clear the snow. in the late 1800s, plows and shovelers worked together to keep streets clear. the trouble was this process took a lot of time and effort. it wasnt until 1920 that an answer appeared in the form of snow loaders. as snow was plowed, it was forced up a scoop on a conveyor belt and dropped into a dump truck.
match the problems with their solutions.
snow loaders removed the snow.
shovelers removed the snow.
plows removed the snow.

Explanation:

To solve the matching, we analyze the text:

1. For the problem of travel on snow - clogged roads before snowplows: The text says "In the 1840s, however, the first patents were issued for plows attached to carts pulled by horses. These early snowplows cleared roads, making it easier to travel." So the solution is "Plows removed the snow."
2. For the problem of huge snow piles blocking storefronts: The text says "One way to deal with this was to hire shovelers to clear the snow." So the solution is "Shovelers removed the snow."
3. For the problem that plows and shovelers' process took a lot of time and effort: The text says "It wasn't until 1920 that an answer appeared in the form of snow loaders. As snow was plowed, it was forced up a scoop on a conveyor belt and dropped into a dump truck." So the solution is "Snow loaders removed the snow."

Answer:

1. Problem: Travel on snow - clogged roads before snowplows; Solution: Plows removed the snow.
2. Problem: Huge snow piles blocking storefronts; Solution: Shovelers removed the snow.
3. Problem: Plows and shovelers' process took too much time and effort; Solution: Snow loaders removed the snow.
