Read the following passage and answer the questions concerning to it:
In summer a decomposed unidentified dead body was found floating in a pond. the post mortem examination revealed the presence of weeds in the hand of the deceased. The internal examination of the dead body showed the presence of froth in the trachea and diatoms in the lungs.
47. The floating of dead body shows that the death was caused:
- Within 4 hours
- 4 to 12 hours
- 12 to 24 hours
- More than 3- 4 days
Answer and Explanation
Answer: (3) 12 to 24 hours
Explanation:
-> When a person’s body rests inside the water, the decomposition by the human gut bacteria increases by multiple times which produces an immersive amount of gases such as carbon dioxide, methane, hydrogen sulfide, etc.
-> This all leads to the ballooning of the body and its density becomes less than the water.
-> Hence, the body floats. The range is 12 to 24 hrs because it depends upon the body type (fat tissues).
48. The presence of:
- Weed in hands
- Diatoms in lungs
- Froth in trachea
- All of the above will ascertain that it is an antemortem drowning
Answer and Explanation
Answer: (4) All of the above will ascertain that it is an antemortem drowning
Explanation: No explanation for this 2005 June solved NTA UGC NET forensic paper.

Answer: (3) Laundry and tailor marks on cloths
Explanation:
-> Usually, cloths resist decomposition even they submerged for 3 to 4 days.
-> So, by using their laundry and tailor marks, the victim can be identified.
50. The fingerprint of the deceased can be obtained by:
- Visual examination
- Infrared photography
- X-ray Photography
- Above all methods
Answer and Explanation
Answer: (1) Visual examination
Explanation:
-> Visual examination: Most common and straightforward method for capturing fingerprints, often using fingerprint powder and lifting methods.
-> Infrared photography: Generally not used for fingerprinting; more commonly used for examining materials not visible in regular light.
-> X-ray Photography: Not used for obtaining fingerprints; typically used for imaging internal structures.
