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.'

Rationale: The word 'spurious' in this sentence means something that is false or not genuine. In this context, the researcher's argument was misleading or deceitful, confusing even the experts. 'Bogus' means not genuine or false, which aligns closely with the intended meaning of 'spurious.' The other choices, 'obscure,' 'baffling,' and 'outrageous,' do not capture the essence of being false or deceitful, making them incorrect in this context.

Choices B, C, and D are incorrect as they refer to different anatomical directions that are not synonymous with 'superior.' 'Bottom' (choice B) refers to 'inferior,' 'Front' (choice C) relates to 'anterior,' and 'Back' (choice D) corresponds to 'posterior.'

Correct Answer: B

Rationale: The term 'flaccid' is commonly used to describe something that is limp, soft, or lacking firmness.

Choice C 'Uncontaminated' and Choice D 'Unusually aggressive' are also incorrect as they do not relate to the definition of flaccid.
