Why is using a flashlight advantageous when taking notes at night?

Using a flashlight to illuminate the writing surface is advantageous for taking notes at night because it provides the necessary light to see clearly what you are writing. In low-light conditions, the inability to see the writing surface can lead to mistakes, misinterpretations, or even missing crucial information. By using a flashlight, the security guard can ensure that they can accurately read what they are writing down and have visibility of their notes, facilitating effective documentation.

The other options touch on relevant aspects of note-taking but do not address the core reason why a flashlight is specifically beneficial in low-light environments. Enhancing clarity of thoughts, preventing digital distractions, and keeping the notebook dry are not directly linked to the primary function of a flashlight in this context. The flashlight’s role is fundamentally about providing illumination for accurate writing and note-taking.
