What is the first step in testing a pencil's writing ability?

• A. Check if the pencil can write on normal paper
• B. Verify its weight
• C. Inspect the paint color
• D. Measure its length

Answer: (A)

The first step in testing a pencil's writing ability is to check if the pencil can write on normal paper. This action directly assesses the primary function of a pencil, which is to produce marks on a writing surface. The essential measure of a pencil's effectiveness is its ability to deliver an appropriate line or mark when applied against paper.

Evaluating the writing ability begins with this foundational capability, as it directly informs whether the pencil meets its intended purpose. Other options, while relevant in different contexts, do not directly contribute to understanding whether the pencil effectively serves its core function. For example, verifying weight, inspecting paint color, or measuring length might be useful for quality control or aesthetic evaluation, but they do not provide direct feedback on the pencil's performance as a writing instrument.
