Question

the prefix mono- means one. a monologue is a long speech by one person.
if a word is \monosyllabic,\ it
a has many syllables.

b has only one syllable.

c has no syllables.

d has too many syllables.

Explanation:

The prefix "mono - " means "one" as given. The word "monosyllabic" is composed of "mono - " (one) and "syllabic" (related to syllables). So by analyzing the prefix, we can conclude that a monosyllabic word has only one syllable. Option A says "many syllables" which is incorrect as "mono - " means one. Option C says "no syllables" which is wrong. Option D says "too many syllables" which also goes against the meaning of the prefix "mono - ".

Answer:

B. has only one syllable.
