Question

Which sentence contains a supporting detail that answers the question, What did the Sumerians need to keep track of?

Main Idea: The greatest gift the Sumerians gave the world was the invention of writing.

Sumerians

The greatest gift the Sumerians gave the world was the invention of writing. The Sumerians were a wealthy people. They needed some way to keep track of what they owned. They began drawing pictures. They used a reed as a pen. They drew on soft pieces of clay. The soft clay was then dried in the sun. The tablet became a permanent record. Later, the Sumerian drawings changed into wedge-shaped symbols. This kind of writing is called cuneiform. By putting symbols together, the Sumerians could write entire sentences.

A.
The Sumerians were a wealthy people.

B.
By putting symbols together, the Sumerians could write entire sentences.

C.
They needed some way to keep track of what they owned.

Answer 1

I think the answer is C

Answer 2

Answer: The right answer is the C) They needed some way to keep track of what they owned.

Explanation: Just to elaborate a little on the answer, it can be added that since the question asks WHAT the Sumerians needed to keep track of, options A and B are irrelevant, since they do not provide a precise answer — they indicate that the Sumerians were wealthy (that's, nevertheless, a clue, since wealth and ownership go hand in hand) and that they could write entire sentences by putting symbols together. Option C is, therefore, the correct alternative. The Sumerians needed to keep track of what they owned.
