Correct Answer: C

Rationale: Contact dermatitis occurs through the sense of touch when the skin comes into direct contact with irritants or allergens, leading to an inflammatory reaction. This condition is commonly caused by the skin being in contact with items like certain chemicals, fabrics, plants, or metals, resulting in redness, itching, and sometimes blisters. The other choices (smell, taste, sight) do not relate to the cause of contact dermatitis, which specifically involves the skin's direct contact with irritants or allergens.

Correct Answer: D

Rationale: The correct answer is D, 'Scar.' A cicatrix is a scar, which is a mark left on the skin or within body tissue after the healing of a wound or injury. Choices A, B, and C ('Beetle,' 'Scalpel,' and 'Antidote') are incorrect as they do not represent synonyms for cicatrix.

Correct Answer: D

Rationale: The outer bone in the lower leg is called the fibula, not fascia, fibrous, or filial. The fibula is a slender bone that runs alongside the larger tibia in the lower leg. While it provides stability and support to leg muscles, its main function is not weight-bearing like the tibia. Therefore, the correct answer is the fibula.

Correct Answer: C

Rationale: In this context, the word 'quandary' refers to a state of uncertainty or confusion caused by being faced with a difficult decision or choice. This matches the meaning of option C. Choices A, B, and D are incorrect because 'quandary' does not relate to a place where rocks are mined (A), a journey of discovery (B), or a major attempt or trial (D), but rather to a state of uncertainty or confusion.

Correct Answer: D

Rationale: A restricted diet is limited in some way, such as reducing the intake of certain foods, food groups, or nutrients. It may involve limitations on quantity, frequency, or types of foods consumed. This restriction could be related to health factors, allergies, sensitivities, ethical reasons, or personal preferences. Choice A, 'low in fat,' is too specific and does not encompass the broad concept of restriction in a diet. Choice B, 'vegetarian,' refers to a specific dietary pattern but does not necessarily indicate restriction. Choice C, 'banned,' is incorrect as it implies a complete prohibition rather than limitation, which is characteristic of a restricted diet.
