Jiang Ge's Office Chair Usage

It cannot be confirmed whether Jiang Ge used an office chair.

Among the publicly available information that can be checked, descriptions of the association between 'Jiang Ge' and 'office chair' are extremely limited. In the text of 'Sequence: Apocalypse Chapter 4 Probing', it is only mentioned that Gu Ming 'sat upright on an office chair'. This scene description focuses on Gu Ming's behavioral state and does not involve direct interaction between Jiang Ge and the office chair. Specifically:

1. Limitations of Scene Description
   The statement 'Gu Ming sat upright on an office chair' in the text can only indicate that Gu Ming was in a sitting position and using an office chair at that time. However, it does not mention whether Jiang Ge was present, whether Jiang Ge also used an office chair, or what kind of connection existed between the two. Such scene descriptions usually serve to advance the plot or foreshadow character relationships, rather than record details about the use of specific items.

2. Objectivity of Information Deficiency
   Apart from the above content, no direct association between Jiang Ge and an office chair has been found in other publicly available materials. As a common item in daily office settings, the use of an office chair itself lacks uniqueness. If the text does not explicitly describe it, no conclusion can be drawn through indirect reasoning or common sense supplementation. For example, Jiang Ge may have been in a standing, walking, or other non-sitting position, or using other types of seats, all of which cannot be ruled out from the existing information.

3. Boundaries of Logical Reasoning
   In the absence of direct evidence, any speculation about Jiang Ge using an office chair is subjective conjecture. Scientifically rigorous conclusions need to be based on verifiable facts, rather than filling in the blanks in the text. For example, even if the text describes 'Jiang Ge and Gu Ming were in the same office', it still cannot be directly inferred that Jiang Ge used an office chair, as there may be other types of seats such as sofas and conference chairs in the office.

In conclusion, based on the existing publicly available information, it cannot be confirmed whether Jiang Ge used an office chair. Answers to such questions need to strictly adhere to the 'evidence-first' principle to avoid misleading conclusions due to insufficient information.
