Answer:
The solution, I think, is to try our best and see what happens.
Explanation:
A comma is a slight pause in any given sentence that allows a reader to take a break though for only a short time. It is also used in many ways, including the separation of two or more independent clauses in a sentence.
The five rules of using a comma are that it must be used after an introductory phrase/ clause, after a parenthetical phrase or clause, to separate two independent clauses that are joined by a coordinating conjunction, to separate items in a list, and before any quotations.
Therefore, the clause "I think" in the given sentence will be put in between commas. Thus, the correct sentence will be <u>"The solution, I think, is to try our best and see what happens."</u><u>
</u>
"A tiny white diamond sparkled on her finger" technically has an error since there should be a comma after "tiny" although this is becoming more common usage.
I believe the answer is C. because in the passage it states that the Egyptians observed the beetles useful work.
Hope this helps!
