Question

sort the words according to the meanings of their shared roots.
life
biology
circle

do or make
artifact
encircled
factor
antibiotic
circus
manufacture
circular

Explanation:

1. For the "life" category (root related to life, as seen with "biology" and "antibiotic" which has "bio-" meaning life): The word "antibiotic" should be placed here since "bio-" in it relates to life.
2. For the "circle" category (root related to circle, as seen with words like "circus", "encircled", "circular"): The words "circus", "encircled", "circular" should be placed here as they relate to the concept of a circle (e.g., "circus" has "circ-" related to circle, "encircled" means surrounded in a circle - like way, "circular" is related to a circle).
3. For the "do or make" category (root related to doing or making, as seen with words like "artifact", "manufacture", "factor"): The words "artifact", "manufacture", "factor" should be placed here. "Artifact" is something made, "manufacture" means to make, "factor" can relate to making or doing in a mathematical or causal sense (but in terms of root meaning related to do/make, these fit).

Answer:

• life: antibiotic
• circle: circus, encircled, circular
• do or make: artifact, manufacture, factor
