To answer the question regarding the meaning of "Non-Manual Markers" in the context of sign language, here's a detailed explanation:

Non-Manual Markers (NMMs) are a crucial component of sign language that supplement and modify the signed message without the use of hands. They typically include facial expressions, head movements, and various body postures. These markers provide essential grammatical and contextual information, helping convey tone, negation, emotion, and other nuances that are not expressed through manual signs alone.

1. Modifying how you sign a sign: This option is somewhat correct since NMMs can alter the meaning or tone of a sign, but it doesn't fully capture the essence of what NMMs are.

2. Using facial expressions, etc. to modify the sign: This is the most accurate representation of Non-Manual Markers, as they are heavily reliant on facial cues and body language.

3. Negating the sign used: While negation can be accomplished through NMMs, this definition is too narrow and doesn't encompass the broader range of functions that NMMs serve.

4. None of the above: This option is incorrect because option two accurately describes NMMs.

Final Answer

The correct answer is Using facial expressions, etc. to modify the sign.
