Mock Test Set-2

Q1. In forensic entomology, which insect species is typically the first to colonize a corpse?

   A) Blowflies (Calliphoridae)

   B) Flesh flies (Sarcophagidae)

   C) Rove beetles (Staphylinidae)

   D) Hide beetles (Dermestidae)

Answer: A) Blowflies (Calliphoridae)  

Explanation: Blowflies are often the first insects to colonize a corpse, attracted by the odor of decomposition.

Q2. Which of the following drugs is NOT commonly detected through hair analysis in forensic toxicology?

   A) Cocaine

   B) Heroin

   C) Marijuana

   D) Benzodiazepines

Answer: D) Benzodiazepines

Explanation: While benzodiazepines can be detected in blood or urine samples, they are less commonly analyzed through hair analysis due to their low incorporation into hair.

Q3. What is the primary method used for estimating the age of skeletal remains in forensic anthropology?

   A) DNA analysis

   B) Dental examination

   C) Radiocarbon dating

   D) Epiphyseal fusion

Answer: D) Epiphyseal fusion

Explanation: Epiphyseal fusion, the process of assessing the fusion of bone growth plates, is a key method for estimating the age of skeletal remains in forensic anthropology.

Q4. Which tool mark comparison method relies on the examination of three-dimensional surface features?

  A) Striation analysis

  B) Micromorphology analysis

  C) 3D topography analysis

  D) Microscopy analysis

Answer: C) 3D topography analysis

Explanation: This method involves capturing and analyzing three-dimensional surface features of tool marks using specialized equipment.

Q5. What term describes the phenomenon where DNA fragments of different lengths migrate at different rates in gel electrophoresis?

   A) DNA polymorphism

   B) Gel resolution

   C) Allelic ladder

   D) DNA ladder

  Answer: B) Gel resolution

  Explanation: Gel resolution refers to the separation of DNA fragments based on size during gel   electrophoresis, where shorter fragments migrate faster than longer ones.

Q6. Which digital forensic technique involves analyzing the temporal relationships between digital artifacts to reconstruct events?

   A) File carving

   B) Timeline analysis

   C) Metadata extraction

   D) Hash analysis

Answer: B) Timeline analysis

Explanation: Timeline analysis involves examining timestamps and file metadata to create a chronological sequence of events related to digital evidence.

Q7. In forensic psychology, which assessment tool is commonly used to evaluate an individual's risk of future violent behaviour?

  A) MMPI-2

  B) Hare Psychopathy Checklist-Revised (PCL-R)

  C) Violence Risk Appraisal Guide (VRAG)

  D) Structured Clinical Interview for DSM Disorders (SCID)

Answer: C) Violence Risk Appraisal Guide (VRAG)

Explanation: The VRAG is a structured tool used to assess an individual's risk of future violent behavior based on various risk factors.

Q8. Which facial reconstruction method involves digitally overlaying facial soft tissue onto a skull model?

   A) Anatomical reconstruction

   B) Artistic reconstruction

   C) Forensic facial approximation

   D) Three-dimensional printing

Answer: B) Artistic reconstruction

Explanation: This method involves using computer software to digitally sculpt facial features onto a skull model, creating an approximation of the individual's appearance.

Q9. Forensic linguists analyze which linguistic feature to identify an individual's writing style?

    A) Lexical density

    B) Syntactic complexity

    C) Grapheme frequency

    D) Function word usage

Answer: D) Function word usage

Explanation: Function words, such as articles, pronouns, and conjunctions, are highly individualistic and can be used to identify an individual's writing style in forensic linguistics.

Q10. What is the primary goal of phylogenetic analysis in microbial forensics?

     A) Identifying unique microbial species

     B) Establishing evolutionary relationships

     C) Analyzing antibiotic resistance genes

     D) Determining geographic origin

 Answer: B) Establishing evolutionary relationships

Explanation: Phylogenetic analysis in microbial forensics aims to reconstruct the evolutionary history of microorganisms to understand transmission pathways and trace the source of infectious diseases.
