Question

what type of context clue is used to determine the meaning of abnormalizes? example
after many decades of human manipulation, bulldogs are so far from their natural ancestors that they commonly suffer from abnormalities, such as small snophres and closed nostrils. our efforts to breed so many of these dogs have dulled the bloodline, thinning and weakening it further with every generation. rather than creating a sustainable breed of dog, we have obtained an unsupportable dog breed that cannot be maintained for much longer.

Explanation:

To determine the context clue for "abnormalizes", we analyze the text. The example (about dog breeding) shows a contrast: creating a sustainable breed vs an unsustainable one. The key is the contrast between "sustainable" (self - maintaining, long - lasting, recurring) and the result of "abnormalizes" (unsustainable). So the context clue is contrast (antonym - based), as "sustainable" is the opposite of what "abnormalizes" leads to (unsustainable dog breed).

Answer:

The context clue type is contrast (antonym - based). The word "sustainable" (with meanings like self - maintaining, long - lasting, recurring) is used in contrast to the effect of "abnormalizes" (leading to an unsustainable dog breed).
