Read the following passage from “To Fly.” What is the author saying about humans?

For millennia, the idea of being able to fly occupied human dreams and fantasies. Waddling around on Earth’s surface as majestic birds flew overhead, perhaps we developed a form of wing envy. One might even call it wing worship.

• They want the powers that they observe in other creatures.

• They sometimes pray to birds because birds are magnificent.

• They should give up on the notion that they will ever outfly birds.

• They live in a world of fantasy instead of keeping their feet on the ground.

We did, however, ultimately learn to fly because of the technological ingenuity afforded by our human brains. And of course, while birds can fly, they are nonetheless stuck with bird brains. But this self-aggrandizing line of reasoning is somewhat flawed, because it ignores all the millennia that we were technologically flightless

What does the author mean when he says that this line of reasoning is flawed?

• We may be smarter than birds, yet we failed to fly until very recently.

• Bird brains may be just what is needed in order to fly successfully.

• We cannot logically compare the brains of two different species.

• We humans typically exaggerate our accomplishments.
