46. Vicat apparatus is used for analysis of cement to observe:
| A. Compressive strength | B. Elemental composition |
| C. Standard consistency | D. texture |
Ans.- C. Standard consistency
Explanation:
Vicat Apparatus determine consistency, time of set, and false set of hydraulic cement, mortar, and grout.
47. Which of the following pairs is not matched correctly?
A. Algor Mortis- Cooling of body
B. Putri Mortis – Putrefaction of body
C. Rigor Mortis – Stiffening of body
D. Livor Mortis – Bluish discoloration of body
Ans.- B. Putri Mortis – Putrefaction of body
Explanation:
The time difference between the time of death and the examination of the body is known as the Post Mortem Interval (PMI). There are 4 stages of PMI through which the body passes: Pallor Mortis, Algor Mortis, Rigor Mortis and Livor Mortis.
Pallor Mortis: The first change that occurs in a corpse is the increased paleness in the face and other parts.
Algor Mortis: After cessation of body functioning the dead body start to drop its temperature. this is also known as cooling of body.
Rigor Mortis: After a few hours the body starts to harden. The muscles will shrink and become stiff.
Livor Mortis: after about 36 hours Rigor mortis begins to disappear and Livor Mortis takes place which is also known as secondary flaccidity. in this stage blood collects in the lower part of body.

50. Which of the following physiological parameters is not assessed in polygraph testing?
| A. Blood pressure | B. Lung air volume |
| C. Pulse rate | D. Skin conductivity |
Ans.- B. Lung air volume
Explanation:
The Polygraph test also know as lie detection test is a psycho-biological examination to check the legitimacy of a person’s statements with the help of computerized device known as a lie detector or polygraph. This instrument measures 6 different following types of autonomic physiological changes that are recorded in graph form. They are given following:
(i) Thoracic respiration
(ii) Abdominal respiration
(iii) Galvanic skin resistance
(iv) Blood pressure
(v) Movement or muscular pressure
(vi) Finger pulse
