What are three things that Spotlight can show results for other than searches?

The correct response highlights three functionalities that extend beyond simple keyword searches in Spotlight. Dictionary definitions allow users to quickly look up meanings of words without needing to open a separate application, enhancing accessibility to language resources. Calculations enable users to perform basic mathematical operations directly within the Spotlight interface, simplifying tasks that involve quick computations. Measurement conversions provide users with the ability to convert values from one unit to another, such as converting miles to kilometers or Fahrenheit to Celsius, all without navigating away from their current task.

These capabilities make Spotlight not just a search tool but a multifunctional assistant, streamlining common tasks and enhancing productivity. The other options, while they do present useful features, do not encapsulate these specific functionalities of quickly accessing definitions, performing calculations, and converting measurements directly through Spotlight.
