Statement Analysis: Watch Adjustment and Local Time

This question asks us to evaluate two statements about setting a watch based on the sun's position and whether that reflects the local time.

Statement A: Sun's Position and Watch Setting

Statement A claims that a watch can be adjusted to read 12 o'clock when the sun is at its highest point in the sky, signifying mid-day (local solar noon).

• The sun reaches its highest point in the sky at solar noon for a specific location.
• Historically and conceptually, 12:00 PM is associated with this solar noon.
• Therefore, adjusting a watch to 12:00 when the sun is highest is a valid practice related to setting time based on solar observation.

Based on this, Statement A is true.

Statement B: Watch Time and Local Time

Statement B suggests that a watch adjusted as described in Statement A will show the local time for that place.

• Local time is determined by the sun's position (specifically, its longitude) at a particular location.
• Setting a watch to 12:00 PM when the sun is at its highest point directly uses the sun's position to determine the time for that specific place.
• This process defines the solar time, which is the basis of local time before standard time zones were widely adopted.

Thus, the time shown by such a watch accurately represents the local time. Therefore, Statement B is true.

Conclusion on Statements

Since both Statement A (the ability to set a watch to 12 o'clock at solar mid-day) and Statement B (such a watch showing local time) are factually correct, the option stating that both are true is the correct choice.

• Statement A: True
• Statement B: True

Conclusion: Both statements A and B are true.
