Fire fueled by combustibles such as paper is best extinguished with

Correct Answer: A

Rationale: Fires fueled by combustibles like paper are Class A fires, best extinguished by cooling and soaking. 'Pressurized water,' is correct because it douses flames and prevents reignition, per fire safety standards (e.g., NFPA). 'Compressed gas,' (e.g., CO2) suits electrical fires (Class E), not paper. 'Liquid soap,' is ineffective and impractical. 'Graphite powder,' is not a standard extinguisher. Water's efficacy on Class A materials—wood, paper—makes A the precise answer, aligned with firefighting protocols.

Correct Answer: B

Rationale: Tactile cells (Merkel cells) in the skin detect touch and pressure. 'Tactile cells,' is correct, linked to sensory nerve endings, per histology (e.g., Ross & Pawlina). 'Dendritic cells,' are immune-related. 'Keratinocytes,' form the skin barrier, not sensory. 'Melanocytes,' produce pigment. Tactile cells' mechanoreceptor role makes B the accurate answer.

Correct Answer: C

Rationale: The anterior pituitary secretes trophic hormones regulating growth and glands, but oxytocin comes from the posterior pituitary. 'Oxytocin,' is correct as the exception, per endocrinology references like Costanzo's Physiology. 'Growth hormone,' stimulates growth. 'Prolactin,' promotes lactation. 'Adrenocorticotrophic hormone,' targets adrenals. Oxytocin, stored and released by the posterior pituitary after hypothalamic synthesis, aids labor and lactation, making C the precise answer, distinct from anterior pituitary functions.

Correct Answer: D

Rationale: The suspensory ligament of the ovary (infundibulopelvic ligament) anchors it to the pelvic wall, carrying vessels. 'Suspensory ligament,' is correct, per anatomy texts like Moore, distinct from other supports. 'Broad ligament,' encloses tubes and ovaries, not a direct anchor. 'Ovarian ligament,' connects ovary to uterus. 'Round ligament,' supports the uterus. The suspensory ligament's pelvic attachment makes D the accurate answer.
