'Face' is related to 'Expression' (a typical action/outcome) in the same way as 'Hand' is related to which typical action/outcome?

Introduction / Context:
Here the relation ties a body part to a typical outward sign or action associated with it. A face commonly conveys an expression. We must find the analogous typical manifestation for 'hand'.

Given Data / Assumptions:

• Face → expression (smile, frown, etc.).
• Hands communicate through movements.
• Options include several hand-related actions.

Concept / Approach:
Seek the general, category-level correlate: not a single specific act, but the broader communicative function comparable to 'expression'.

Step-by-Step Solution:
1) Identify category for the first pair: body part → general manifestation.2) For hands, the general communicative manifestation is 'gesture'.3) Choose 'Gesture' over specific acts like 'handshake' or 'pointing'.

Verification / Alternative check:
Nonverbal communication theory classifies hand movements as gestures, analogous to facial expressions for the face.

Why Other Options Are Wrong:

• Work: Too broad/functional; not primarily communicative.
• Handshake: A specific act, not a general manifestation.
• Pointing: Specific act; too narrow.
• None of these: Incorrect because 'Gesture' fits best.

Common Pitfalls:
Choosing a specific instance instead of the general category parallel to 'expression'.

Final Answer:
Gesture
