Indoor Plumbing.
Primarily, it has provided a greater level of sanitation in modern life. The use of running water to wash your hands and bathe reduces the likelihood of spreading germs and bacteria. The ability to cleanly remove waste away from heavily populated areas allows for cleaner air, thus, fewer respiratory related illnesses. Ultimately, it has propelled civilizations towards the better quality of life that we enjoy today.
The correct answer is B. Life on earth is important on its own right.
They valued human life and individualism above everything else, putting the person forefront as more important than the society.

From Keplers discovery, scientists were also able to infer that the closer a satellite is to an object, the stronger the force of attraction, hence it must travel faster in order to maintain orbit. Relying on this formula, we are able to see that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. So if we wanted to put a satellite in a circular orbit at 500 km above the surface (what scientists would call a Low Earth Orbit LEO), it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2 or 7615.77 m/s. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits.
