PrepTest 83, Section 2, Question 15
Physicists attempting to create new kinds of atoms often do so by fusing together two existing atoms. For such fusion to occur, the two atoms must collide with enough energy�that is, at high enough speeds�to overcome the electromagnetic force by which atoms repel each other. But if the energy with which two atoms collide greatly exceeds the minimum required for the fusion to take place, the excess energy will be converted into heat, making the resulting new atom very hot. And the hotter the atom is, the greater the chance that it will immediately split apart again.

Which one of the following is most strongly supported by the information above?
When physicists create new kinds of atoms by fusing together two existing atoms, the new atoms usually split apart again immediately.
If a new atom produced by the collision of two other atoms immediately splits apart again, then the collision did not produce enough energy to overcome the electromagnetic force by which atoms repel each other.
The stronger the electromagnetic force by which two atoms repel each other, the hotter any new atom will be that is created by the fusion of those two atoms.
Whenever two existing atoms are made to collide and fuse together into a new atom, little energy is produced in the collision unless the new atom immediately splits apart.
If two atoms collide with considerably more energy than is needed for fusion to take place, the new atom will be likely to immediately split apart again.
