Part B: Provide Passage Architecture & Core Elements
Main Point: The MediScan platform uses a two-step process where radiologists input data and then AI analyzes it to detect cancer.
Argument Flow: The passage introduces the MediScan platform, then describes the sequential process it uses - first radiologists upload information, then the AI algorithm analyzes the data to identify potential problems.
Step 2: Interpret the Question Precisely
This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.
Step 3: Prethink the Answer
- Looking at our analysis, we have a clear sequence: radiologists do something FIRST (upload scans and enter history), then the AI does something (examines patterns)
- We need a transition that shows this chronological order - that the AI's work happens as the next step after the radiologists' work
- The relationship needed is sequential/chronological, not similarity, contrast, or example
For instance,
- This introduces an example or illustration
- The AI examining patterns isn't an example of radiologists uploading scans - it's a different step entirely
Next,
- This shows chronological sequence and progression
- Perfectly matches the process flow: first radiologists upload → next AI examines
- Creates the logical step-by-step relationship we identified
Similarly,
- This shows similarity or parallel actions
- The AI examining patterns is not similar to uploading scans - these are completely different actions in the process
In contrast,
- This shows opposition or difference
- The AI's work doesn't contrast with the radiologists' work - they're complementary steps in the same process
