21 A forensic investigator finds a shoe impression that is invisible to the naked eye and requires oblique lighting or chemical treatment to be visualized. How should this impression be classified based on visual appearance?

22 A muddy footprint left on a tiled floor that is clearly visible without any enhancement belongs to which category of impression?

23 An impression made when a shoe presses into soft soil, creating a three-dimensional mould of the sole, is best described as a:

24 Which of the following is the primary forensic significance of analyzing a suspect's gait pattern from a series of footprints?

25 In gait analysis, the perpendicular distance between the successive left and right footprints from the line of direction is known as the:

26 The scientific study of lip prints for the purpose of personal identification is known as:

27 A lip print recovered from a drinking glass at a crime scene is valuable because the pattern of lip grooves is:

28 During a homicide investigation, a bite mark on the victim's skin needs to be linked to a suspect. Which forensic feature makes bite mark comparison possible?

29 Which of the following combinations correctly represents common locations where bite marks are found in violent crimes?

30 Ear prints are most commonly recovered from which location at a burglary scene?

31 Which anatomical features of the ear provide the individualizing detail used in ear print comparison?

32 A long, dark rubber mark left on a road when a driver brakes hard and the wheels lock is best classified as a:

33 At a scene where a body was pulled across the ground to a vehicle, the resulting marks on the soil would most likely be characterized as:

34 While examining tyre impressions from a hit-and-run, an investigator notes the four tyres show two different tread patterns. This most likely indicates:

35 In tyre tread nomenclature, the raised rubber portions that contact the road and provide grip are called:

36 Uneven wear appearing only on one edge (shoulder) of a tyre's tread most commonly indicates:

37 Which of the following would be considered an individual characteristic rather than a class characteristic of a footwear impression?

38 A tool mark examiner concludes a screwdriver made an impression at a scene. The unique microscopic striations along the tool's edge that allow this match are an example of:

39 A crowbar used to force open a window frame leaves a mark where the tool was pressed and levered, compressing the wood. This is best described as which type of tool mark?

40 When bolt cutters slide along and shear through a padlock shackle, the resulting parallel scratch pattern on the cut surface is classified as a:

41 A forensic examiner recovers a shoeprint on a dusty tile that is only visible when the surface is illuminated with oblique lighting at a low angle. This impression contains no foreign material transferred to or from the shoe. How should this impression be most accurately classified?

42 Two footwear impressions are compared. Both share the same tread pattern, size, and manufacturer's logo, but one shows a distinctive cut across the heel and an embedded pebble void. Which conclusion is best supported?

43 An investigator analyzes a trail of footwear impressions and measures a consistent stride length, a wide straddle, and a marked outward foot angle on the left side only. What is the most defensible forensic inference?

44 At a collision scene, an examiner observes a skid mark that gradually darkens and narrows before abruptly ending, followed by a gap and then a gouge in the asphalt. What sequence of events is most consistent with these features?

45 During examination of a vehicle involved in a hit-and-run, three tyres match the OEM specification while one is a different brand with a mismatched tread depth. Why is this forensically significant?

46 A tyre impression shows shallow shoulder ribs but relatively deeper central grooves, with feathering visible along one edge of the tread blocks. What condition is most strongly indicated?

47 In cheiloscopy, an examiner classifies a lip print showing grooves that branch in a Y-shape across the vermilion border. Under the Suzuki and Tsuchihashi classification, which type does this correspond to?

48 A pathologist examines a bite mark exhibiting a central area of ecchymosis surrounded by two opposing arches with abrasions. Which factor most limits the evidentiary reliability of matching this mark to a suspect's dentition?

49 An ear print is lifted from a window pane at a burglary scene. Which combination of features contributes class-level rather than individualizing information to the comparison?

50 A forced entry shows a striated mark on a door strike plate produced by a screwdriver used as a lever. To individualize the tool, the examiner must primarily compare which feature set?

51 At a scene, investigators recover: (1) a shoeprint in soft mud, (2) a fingerprint dusted on glass, and (3) a chisel mark on a wooden window frame. Which statement correctly categorizes the dimensional nature of these three?

52 An examiner must distinguish a barefoot impression from a sock-clad foot impression at a scene. Which feature would most reliably confirm a bare foot rather than a sock?

53 A reconstructionist differentiates a yaw mark from a straight skid mark. Which characteristic uniquely identifies a yaw mark?

54 Which principle most fundamentally underlies the evidentiary value of all impression evidence in forensic science?

55 An examiner classifies bite marks by mechanism. A bite showing tearing, avulsion of tissue, and irregular margins most likely represents which type?

56 A negative impression and a positive impression of the same object are compared. Which statement correctly describes their relationship?

57 During a footwear comparison, the examiner finds matching class characteristics but only one small, poorly reproduced individual feature in the questioned print. What is the most appropriate conclusion?

58 In tread nomenclature, the continuous circumferential raised portions are called ribs, and the transverse recesses are grooves. If a tyre impression shows the tread wear indicator bars flush with the tread blocks, what does this signify?

59 A latent lip print is suspected on a drinking glass at a scene. Which statement about the nature and persistence of lip prints is most accurate?

60 Tool marks are broadly divided into impressed (compression) and striated (friction) marks. A padlock hasp cut by a bolt cutter shows two opposing pinched surfaces with fine parallel lines running perpendicular to the cut face. How should these be classified and used?
