Major shifts, that is shifts in the paradigms, are not very frequent - they would make scientific research unstable, as any result of a smaller study could be made invalid by a paradigm shift,

Therefore the best answer is
<span>Major
shifts in scientific views very rarely occur, but minor modifications
of prior knowledge are continually made based on new research.</span>
The phrase "E Pluribus Unum" actually means "out of many, one". So the answer choice that best fits that definition would be A! The reason why is because the phrase means that the U.S is composed of many, but that it's united.
It takes about 15 arrows just to be safe..
