Ludwig's WRAP-UP
The phrase "be challenged against" is an infrequent and grammatically questionable construction, as Ludwig AI points out. While it appears across several contexts like news, science, and wikis, its usage isn't recommended due to better alternatives existing. The primary issue lies in the improper use of "against" with "challenged"; more appropriate options include "be challenged by" or "be tested against". To maintain clarity and grammatical accuracy, opting for these alternatives is always better. Related phrases focus on confrontation, competition, or assessment, differing in word choice and grammatical nuance. Therefore, it's crucial to avoid "be challenged against" in formal writing and choose clearer, more standard expressions.
