Question

sort the words according to the meanings of their shared roots.
look at or observe
speak
professor
kaleidoscope
confession
stethoscope
telescope
microscope

Explanation:

To solve this, we analyze the roots of the words. The root "scope" relates to viewing. Words with "scope" (stethoscope, telescope, kaleidoscope, microscope) fit "look at or observe". Words with "fess" (professor, confession) relate to speaking (professor teaches/speaks, confession is speaking truth), so they fit "speak".

Answer:

For "look at or observe": stethoscope, kaleidoscope, telescope, microscope
For "speak": professor, confession
