Correct Answer: dull

Solution : The most appropriate synonym for the underlined word blunt is the second option.

Explanation: The term blunt in this context refers to the flat, not sharp, side of the sword. To find an appropriate synonym, we need to look for a word that indicates a lack of sharpness.

Dull is the opposite of sharp, and accurately represents the meaning conveyed by blunt in this sentence.

So, the correct sentence would be: He leaned left, bringing the dull side of his sword up flat against his palm.

The meanings of the other options are as follows:

• Sharp: This term indicates a cutting or pointed quality.

• Timid: This term refers to a lack of courage or shyness.

• Keen: This term refers to having a sharp or eager quality.
