Sentence 4 introduces the concept that while biased human decisions have localized effects, the emergence of AI, represented by Al, expands these impacts on a broader scale, providing context for the ensuing discussion.
Considering Sentences 1 and 2, Sentence 1 elaborates on the repercussions of biased decisions within the AI domain, emphasizing that algorithms hosted online and accessed by many lead to more significant adverse effects on larger populations. Sentence 2 clarifies "algorithmic bias," emphasizing that bias stems from the data rather than the algorithms themselves, explaining how algorithms mirror persistent patterns within training data. Therefore, Sentence 2 logically follows Sentence 1.
Sentence 3 notes that despite the widespread influence of AI biases, rectifying them is comparatively easier than addressing biases generated by humans, as it is simpler to identify and correct biases in algorithms than to change deeply ingrained human behaviors. This progression logically follows from the explanation provided in Sentence 2.
So, the correct sequence is option (A): 4123
