Question

chron = \time\ chrom = \color\ meta = \change, beyond\ meter = \measure\ mono = \one\ based on the list of word roots, what is the meaning of the word monochromatic? capable of changing color occurring at a single time consisting of only one color able to measure time

Explanation:

The word root "mono" means "one" and "chrom" means "color". Combining these roots, "monochromatic" would mean consisting of only one color. The other options can be eliminated: "capable of changing color" would relate to "meta - chrom" (since "meta" means change), "occurring at a single time" would relate to "chron" (time), and "able to measure time" would relate to "meter" (measure) and "chron" (time).

Answer:

consisting of only one color
