Step 1: Understanding the question.
This sentence talks about a change in attitudes toward eating meat, so we need to choose a word that indicates a shift or change in thinking.
Step 2: Analyzing the options.
(A) persistence: This suggests that attitudes remained the same, which does not fit the context of change described in the sentence.
(B) transformation: This is the most appropriate option, as it implies a significant change in attitudes.
(C) metamorphoses: While similar to "transformation," this is too specific and poetic for the context.
(D) reconsideration: This suggests that attitudes were simply rethought, but not necessarily changed as profoundly as the context implies.
Step 3: Conclusion.
The correct answer is (B) transformation, as it accurately reflects a significant change in attitudes.
