Which sentence in the passage can be used to conclude that eris is a dwarf planet and not a planet?
eris takes about 557 earth years to orbit the sun. it has a mean surface temperature of about 40 kelvin. it has a nearly spherical shape. it has several other objects in its orbit, though few are as massive as itself. eris is too far away and small to be clearly visible from the earth. scientists used its moon, dysnomia, to measure it. eris is believed to be slightly more massive than pluto. however, both of them are smaller than earth’s moon. eris orbits the sun directly; it is not a satellite of another planet or dwarf planet.

It has several other objects in its orbit , though few are as massive as itself.

Explanation:

A celestial body orbiting the sun is considered  a planet when its mass is more than sum of  all other celestial  bodies moving along with it in its orbit round the sun.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
