Why the other choices are wrong
Choice A
Choice A is incorrect. The sentence indicates who founded the MexiCali Biennial and the years this biennial has taken place; it doesn’t emphasize a difference between the MexiCali Biennial and traditional biennials.
Choice C
Choice C is incorrect. While the sentence clarifies the traditional meaning of biennial with language that could apply to the MexiCali Biennial, it doesn’t mention the MexiCali Biennial by name. Therefore, the sentence doesn’t effectively emphasize a difference between the MexiCali Biennial and traditional biennials.
Choice D
Choice D is incorrect. The sentence notes locations where various biennial exhibitions have been held; it doesn’t emphasize a difference between the MexiCali Biennial and traditional biennials.
