20.And finally, this is a map of where you can find Venus flytraps in the wild:

Flat-looking, nonverdant scene from an airplane window

Someone holding the seed — which looks a bit like the backs of two thighs and buttocks — in front of their face

A person sitting in a large room with comfy chairs, sofa, TV, and wood cabinet, table, and seats, and floor

A person holding up a gray, flat block with a raised surface with crevices

The Oval Office without any furniture or books, just the empty built-in bookcases and the wood floor with a zigzag pattern

With flags, furniture, curtains, and rugs

Baby owl lying flat facedown on sand or dirt

Eyes closed, eyebrows furrowed, and thin lips

A vertical reddish line among the clouds against the curvature of space

A map of the US with a few straight lines, with huge gaps, crisscrossing the country, and Western and Eastern Europe showing a very tangled, extremely dense network of lines, especially in England, France, Austria, and Germany

An open bag of Sour Skittles showing candy-coated Skittles looking like M&M's

A hand holding a PillCam capsule

The sneaker is at least three or four times higher than the can

The cabinet's contents look like glowing, neon-green figurines

Close-up of a manatee's flipper, showing what look like toes and small hairs on the rough surface

A backless bench on a thin, winding train track under trees

Overhead view of people walking down extremely steep, narrow cobblestone stairs alongside a cobblestone edifice

Back view of all three: 1977 has an ornate font for "100," 2003 has a simpler font, 2017 has a new illustration of Independence Hall and a redesigned, large vertical "100" in a different font

An enormous, cavernous empty room with a checkered floor, long poles, and spoked roof

An empty showing the outlines of the US, with only a small border area between North and South Carolina highlighted
