Answer:
a unit of grammatical organization next below the sentence in rank and in traditional grammar said to consist of a subject and predicate
Explanation:
<span>B Experts today estimate 20,000-30,000 laborers worked on the pyramid at any one time.
This is the best option out of all the options. The statement should support the idea that many people were needed to build the pyramid. Options A and C do not really indicate the amount of people the were necessary to build the pyramid. B and D are the only ones that give numbers. Option D however is not correct because even though it says that the work crews needed to be divided into smaller groups, it doesn't give a true indication of the sheer amount of workers needed. Option B is a clear estimate of the tens of thousands of workers necessary to build a pyramid.
</span>
False it actually modifys something that has been left out of the sentence.
