89. Lowering of an animal into steam or hot water to prepare the skin for de-hairing.

a. Flaying

b. Scalding

c. Gambrelling

Explanation: Scalding involves immersing the swine carcass in hot water (typically 58-60°C) to loosen the hair follicles for the subsequent scraping/de-hairing process. Source: Meat Processing Technology.

90. It is the removal of the hide of the carcass.

a. Flaying

b. Scalding

c. Gambrelling

d. None of the above

Explanation: Flaying (or skinning) is the physical process of removing the hide/pelt from large animals like cattle and sheep prior to evisceration. Source: Abattoir Operations and Procedures.

91. It is the process of suspending the carcass for particular operations.

a. Flaying

b. Scalding

c. Gambrelling

d. None of the above

Explanation: Gambrelling involves inserting a "gambrel" stick or hooks through the hind legs (Achilles tendons) of the carcass to hoist and suspend it from the overhead rail for processing. Source: Slaughtering Techniques.

92. It renders the animal insensible before it is killed.

a. Stunning

b. Pithing

c. Sticking

d. None of the above

Explanation: Stunning is a humane slaughter practice that induces immediate unconsciousness and insensibility to pain before sticking (bleeding) occurs. Source: Animal Welfare Act / NMIS.
