Correct Answer: D

Rationale: In the given sentence, the word 'establish' is used in the context of identifying or finding out the specific causes of contact dermatitis through patch tests. The most fitting description for 'establish' in this context is 'Determine,' as it signifies the action of figuring out or ascertaining the specific causes. 'Launch,' 'introduce,' and 'endorse' do not capture the essence of what the physicians are doing in this scenario. They are not launching, introducing, or endorsing the causes; instead, they are trying to determine them through the patch tests.

Correct Answer: A

Rationale: In the sentence, the word 'suppress' is synonymous with the word 'subdue.' To suppress a cough means to reduce or restrain it, which aligns with the meaning of subdue. The other options are incorrect: 'Cure' implies completely eliminating the cough, 'Restore' means to bring back to a former condition, and 'Affect' is too general and does not capture the specific meaning of 'suppress' in this context.

Correct Answer: A

Rationale: The correct answer is A, 'Insignificant.' Paltry and insignificant are synonymous terms that denote something as unimportant, trivial, or of little value. Choice B, 'Punitive,' means inflicting or intended as punishment, which is unrelated to the meaning of paltry. Choice C, 'Prolonged,' means continuing for a long time, which is not a synonym for paltry. Choice D, 'Economical,' means giving good value or service in relation to the amount of money, which is not synonymous with paltry.

Correct Answer: D

Rationale: The word 'elated' means to be ecstatically happy or joyful. Similarly, 'delighted' also means to be extremely pleased or filled with joy. Therefore, 'delighted' is another word that could be used to express the same meaning as 'elated.' Choices A, B, and C are incorrect. 'Edified' means to instruct or enlighten, 'confused' means to be unclear or bewildered, and 'flabbergasted' means to be astonished or amazed, which do not convey the same meaning as 'elated.'

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.
