Question

in a smartphone study run by a u.s. public - health lab working with the centers for disease control and prevention, millions of gps - tagged inhaler puffs are recorded, creating maps so dense that meaningful structure nearly vanishes into static. the analytic tools are meant to help clinicians ____ faint patterns in where and when asthma attacks cluster, patterns that raw spreadsheets alone would bury.

which choice completes the text with the most logical and precise word or phrase?
a discern
b aggregate
c publicize
d encode

Explanation:

To solve this, we analyze the context: the analytic tools help clinicians identify faint patterns in asthma attack clusters (since raw spreadsheets "bury" them, so tools help see them).

• "Discern" means to perceive or recognize, which fits (clinicians need to see these faint patterns).
• "Aggregate" means to gather, not identify patterns.
• "Publicize" is about making known, not identifying.
• "Encode" is about converting, not identifying patterns.

Answer:

A. discern
