4−1−2−3 is the correct order. Sentence 4 introduces the idea that biased decisions made by humans have a localized impact, but with Al's emergence, the impact scale becomes much broader. This sets the context for the discussion to be followed. Now, if we consider Sentences 1 and 2 we can see that Sentence 1 is expanding on the impact of biased decisions in the context of Al, highlighting that algorithms hosted on the internet, accessed by many, result in more significant adverse effects on larger groups of people. Sentence 2 is providing a clarification on the term "algorithmic bias," emphasizing that the foundation of bias lies in the data rather than the algorithms themselves. It explains that algorithms reflect persistent patterns present in the training data. Therefore we can say that Sentence 2 must be following 1. Sentence 3 is pointing out that despite the widespread impact of Al biases, it is comparatively easier to fix them than human-generated biases, as it is simpler to identify and address biases in algorithms than to make people unlearn behaviors learned over generations. This logically follows the point made in Sentence 2. Therefore Sentence 3 must be following Sentence 2 . Therefore the correct order is 4−1−2−3.
