Handwritten additions lack the strong and what type of stroke that the original text has?

The correct answer is that handwritten additions lack the strong and decisive stroke that the original text has.

In the context of handwriting analysis and document examination, the term "decisive" refers to the clear and confident strokes used in original writing. This characteristic is indicative of the fluidity and authority with which the original text was created, as well as the intention behind each stroke. Handwritten additions, often made later and under different conditions, tend to exhibit a lack of this same level of confidence, which can manifest as unevenness or hesitation in the stroke.

These qualities are crucial for forensic document analysis, as the absence of a decisive stroke can be a key indicator in determining authenticity and assessing whether text is original or an addition. Understanding why the original text appears more decisive helps in developing skills for evaluating handwritten documents effectively.
