In each question below, two sentences are given with one highlighted word each. Determine whether the context of the sentence supports the meaning of the highlighted word (1)Same, requires its antonym (2)Opposite, or if the sentence remains meaningful with either (3)Both.
A. How can researchers validate the dubious(a) findings when the initial analysis raised serious concerns about their reliability?
B. Please ensure the team handles the fragile(b) antique artifacts with utmost care during transportation.

Dubious means "doubtful" or "uncertain."  Dubious findings = doubtful/questionable findings Makes sense because concerns about reliability exist.(same) Opposite: Credible / reliable findings "How can researchers validate the credible findings when the initial analysis raised serious concerns about their reliability?" - Does not fit logically. Sentence B:  Fragile means "easily broken."  Items that break easily must be handled with "utmost care."  Using an opposite word like sturdy would make the strict warning of "utmost care" illogical.  Therefore, the context requires the Same meaning.
