Question

structural analysis: prefixes
refix is a group of letters that is added to the beginning of a base
d, also called the root. prefixes change the meanings of words, so it’s
portant to know the meanings of as many prefixes as possible. the
efixes below all relate to position, but some of them also have other
meanings. for example, para- means “besides” but it also means “faulty
or abnormal” and “almost.”
prefix | meaning | examples
epi- | upon | epicenter, epidermis
hypo- | under | hypodermic, hypochondria
intra- | within | intrastate, intramolecular
para- | beside | parallel, parathyroid
peri- | all around | perimeter, periodontal
super- | over and above | supervise, superimpose

Explanation:

First Question (A ______ is a model of excellence used for comparisons)

To solve this, we use the prefix meanings. The prefix "para-" means "beside" or can relate to a model (as in a paragon, which is a model of excellence). Let's check the options:

• F. perigon: "peri-" means "all around", not related to a model.
• H. hypogon: "hypo-" means "under", not related.
• G. paragon: "para-" (beside, or a model) fits as a paragon is a model of excellence.
• J. extragon: "extra-" (not in our prefix list, but means "outside") doesn't fit.

Using prefix meanings:

• "epi-" means "upon". An epiphyte grows upon (on) other plants.
• A. A periphyte: "peri-" means "all around" – not growing on.
• B. An epiphyte: "epi-" (upon) fits, as epiphytes grow on other plants.
• C. A paraphyte: "para-" (beside) – not growing on.
• D. An intraphyte: "intra-" (within) – not growing on.

Using prefix meanings:

• "intra-" means "within". An intrapopulation event is within a population (between its members).
• F. epipopulation: "epi-" (upon) – not within.
• G. intrapopulation: "intra-" (within) fits, as it's an event within the population (between its members).

Answer:

G. paragon
