Which of the following summaries expresses the main points of the passage best?

I believe gravity is the most important aspect of our universe. Without it we would all be floating off
into the universe. There wouldn't be any orbits; instead, all planetary bodies would simply float
around, running into each other when they crossed paths and just wandering forever.

There is a gravitational force between all objects in the universe. Gravitational force is what keeps all
components of our solar system in orbit around the Sun, as well as moons in orbit around planets. The
force of gravity affects Earth's tides and holds us on Earth's surface. The force of gravity between
objects depends on their masses and the distance between them.

Gravity is hard to understand and scientists have little to no understanding of how it works. We know
that gravity is out there, but the specifics are often lost on us. Plants, animals, and humans are all able
to grow tall due to the pull on Earth from the Sun. Without the Sun we would all just stretch out along
Earth's surface
