I am not sure what section you are referring to but probably because the sun is a star.
Do you have more information?
The statement, which correctly describes the motion of the buses is this: THE AVERAGE SPEED OF THE BUSES IS EQUAL.
Speed is defined as the distance traveled per unit time; it measures the rate of moving of an object. It is a scalar quantity, that is, it has only magnitude and no specific direction and it is measured in meter per second. A high speed value implies that an object is moving very fast while a low value indicates that the object is moving slowly. For the two buses given in the question, they both moved the same distance in the same amount of time.
Jonas gives a speech, and the industry leaders change their minds.

The most contrived ending to the above-mentioned story can be that-
“Jonas gives a speech, and the industry leaders change their minds”
The above statement is counted as most contrived amongst the other available statement because It is highly unlikely for industry leaders to get pacified by Jonas advocacy for minimalistic living.
These industry leaders have their core interest and stakes at the challenge and it is highly possible that they won't leave any stone unturned in defaming Jonas as fraud and scamster.
