The sentences given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the numbers as your answer.

  1. If you've seen a little line of text on websites that says something like "customers who bought this also enjoyed that" you have experienced this collaborative filtering firsthand.
  2. The problem with these algorithms is that they don't take into account a host of nuances and circumstances that might interfere with their accuracy.
  3. If you just bought a gardening book for your cousin, you might get a flurry of links to books about gardening, recommended just for you! the algorithm has no way of knowing you hate gardening and only bought the book as a gift.
  4. Collaborative filtering is a mathematical algorithm by which correlations and co- occurrences of behaviors are tracked and then used to make recommendations.

Solution

✅ Correct Answer: 4123

Step 1: Find the opening sentence -> Look for the sentence that introduces the main topic without referring to anything mentioned before.

Step 2: Follow the connections -> Look for words like "this," "these," "the problem" that refer back to previous sentences.


From passage: "Collaborative filtering is a mathematical algorithm by which correlations and co-occurrences of behaviors are tracked and then used to make recommendations."

Thought process:

Sentence 4 defines "collaborative filtering" -> This must come first because other sentences refer to "this collaborative filtering" and "these algorithms"

Sentence 1 mentions "this collaborative filtering" -> Must come after 4 since it refers to the concept just defined

Sentence 2 says "The problem with these algorithms" -> Must come after 1 because "these algorithms" refers back to the collaborative filtering examples

Sentence 3 gives a specific example starting with "If you just bought..." -> This illustrates "the problem" mentioned in sentence 2


Flow check: 4 (definition) -> 1 (example) -> 2 (problem) -> 3 (specific problem example)

The sequence 4-1-2-3 creates a smooth logical progression from definition to example to problem identification to specific illustration.
