Correct Answer: A

Rationale: A stye is an infection that occurs at the base of an eyelash or on the eyelid. It is typically caused by a bacterial infection, leading to redness, swelling, and sometimes discomfort in the affected area. Choices B, C, and D are incorrect because a stye specifically refers to an infection of the eyelid area, not the eardrum, nostril, or scalp.

Correct Answer: B

Rationale: The correct answer is B: Radius. The forearm consists of two long bones: the radius and the ulna. The radius is located on the thumb side of the forearm and is shorter than the ulna, which is on the pinky side. The humerus is the bone located in the upper arm, the scapula is the shoulder blade bone, and the fibula is a bone in the lower leg. Therefore, they are not the shorter bone in the forearm.

Correct Answer: D

Rationale: In this context, the word 'sanctioned' means to authorize or approve. The sentence indicates that the professor gave permission for the field trip to the chemistry lab, which aligns with the meaning of 'authorized.' Choices A, B, and C are incorrect. 'Organized' does not fit the context as the sentence is about granting approval, not arranging. 'Deterred' means to discourage, which is the opposite of what the professor did. 'Neglected' means failed to care for or pay attention to, which is unrelated to the professor approving the field trip.

Correct Answer: C

Rationale: The word 'venal' means susceptible to corruption, especially by bribery. It is often used to describe individuals who are willing to do dishonest or immoral acts in exchange for money or favors. Therefore, the most appropriate synonym for 'venal' among the given choices is 'greedy.' 'Vibrant' means full of energy and life, 'savage' refers to fierce or violent behavior, and 'fortunate' means having good luck or being favored by fortune, none of which capture the meaning of 'venal.'

Correct Answer: C

Rationale: The word 'amalgamate' in the sentence indicates that if the companies come together, combine, or unite as one entity, which aligns with the meaning of 'merge.' Amalgamation often refers to the merging or combining of two or more entities into one. 'Disband' (Choice A) means to break up or dissolve, which is opposite to what happens when companies amalgamate. 'Move' (Choice B) and 'Regroup' (Choice D) are not directly related to the process of companies amalgamating or merging.
