text structures, part 2 — quiz — level d
for a long time, playgrounds remained the same. then, in
the 1960s, adventure playgrounds were introduced.
community volunteers built these playgrounds with left-
over construction materials, such as wood, rope, and
concrete. the playgrounds featured unique climbing
structures, tunnels, bridges, and tire swings.
you can still visit this adventure playground in new york’s
central park.
how were adventure playgrounds
of the 1960s different from
playgrounds of the 1920s?
they were built in small towns as well
as cities.
they had merry - go - rounds and long
slides.
they were made from unused building
materials.
they had swings and climbing
structures.

Explanation:

To solve this, we analyze each option:

• Option 1: The text doesn't mention small towns vs cities for 1960s playgrounds. Eliminate.
• Option 2: Merry - go - rounds and long slides are typical of older (1920s - style) playgrounds, not the unique 1960s adventure ones. Eliminate.
• Option 3: The text says 1960s adventure playgrounds were built by volunteers with "left - over construction materials" (unused building materials). This matches.
• Option 4: Swings and climbing structures were common in older playgrounds too; the 1960s ones had unique structures with leftover materials, so this isn't a distinguishing factor. Eliminate.

Answer:

The option "They were made from unused building materials." (the third option in the list of choices)
