Forensic Document Examination

Step 1: Initial cooling
After the raw material (wood pulp) is cooked, the pulp is cooled in large digesters to stabilize it. So, the process begins with A.

Step 2: Bleaching and addition of additives
Next, the pulp is bleached and beaten, where chemicals, colors, or sizing materials are added to improve brightness and texture. So, the second step is C.

Step 3: Fiber separation
The pulp is then blown under pressure to separate the fibers and remove unwanted materials. So, the third step is D.

Step 4: Refining
Once cleaned, the pulp is sent to refiners where the fibers are cut to the desired size for uniform paper formation. So, the fourth step is B.

Step 5: Final finishing
Finally, the paper sheet is dried and calendered (pressed through rollers) to achieve smoothness and finish. So, the last step is E.

Final Answer:

Principle (Forensic Handwriting):
Non-identity is concluded when there are fundamental, repeated divergences between questioned (Q) and known (K) writings that cannot be explained by natural variation, writing conditions, disguise, or deterioration. In handwriting comparison, the quality of differences (fundamental vs. trivial) is more important than the quantity of similarities.

What counts as “fundamental” differences?
Stable features like letter construction and sequence of strokes, relative proportions, slant and rhythm, pen lifts and connecting strokes, stroke direction and terminals, baseline alignment, pressure patterns, and distinctive diacritic habits. If such features consistently differ, they override numerous general similarities.

Evaluate each statement:

A. “A known and questioned writings have a considerable number of general similarities that outnumber a few fundamental repeated differences.”
➤ Correct for non-identity. Even if similarities are many, repeated fundamental differences (quality) outweigh similarities (quantity). Thus, Q ≠ K.


B. “Presence of identifying attributes and a coexistent lack of basic divergences between questioned and known writings.”
➤ Not supportive of non-identity. “Lack of divergences” suggests the writings may be by the same writer (or, at least, not excludable). This aligns with possible identity, not non-identity. Hence B is excluded.

C. “Presence of identifying attributes and coexistence of a few basic divergences between questioned and known writings.”
➤ Correct for non-identity if those basic divergences are fundamental and repeated (and not explainable by natural variation/conditions). The mention of divergences is the decisive element for exclusion.

D. “If known and questioned writings are very much alike but not identical.”
➤ Taken as supportive of non-identity in exam context: In practice, no two genuine writings are literally identical; however, when “not identical” reflects consistent, fundamental differences on close examination (despite strong overall likeness), examiners conclude non-identity. This option is typically included to test the idea that similarity isn’t sufficiency—diagnostic differences rule.


Therefore, the combination that establishes non-identity is:


Why not B?
Because “lack of basic divergences” is the opposite of what we need to exclude a writer. Without demonstrable divergences, there is no basis for non-identity.
