The given question is about the text California and Mesopotamia: Similarities and Differences.
The options you were given are the following:
The correct option is the first one as it directly states that water transportation helped towns and cities develop faster, making it crucial for the economical development of Mesopotamia. The rest of the options do not.
The second states why overland transportation wasn't the best, why it made things harder. There is nothing about water transportation.
The third simply states that the canals provided the Sumerian and Akkadian peoples with a transportation system. It doesn't say why that's good, unlike the first one.
The fourth would be the worst option as it doesn't include any information about transportation systems.
