Question

read the sentence and study the table.
the womens club held fundraisers on a semiannual basis.

based on the definition of the prefix, what does the underlined word mean?

once a year
twice a year
twice a month
every other year

Explanation:

Analyze the prefix definition

Using the Affixes and Roots knowledge point
The table defines the prefix semi- as "half in value; happening once halfway through a specific time period."

Analyze the base word

The base word is "annual," which means occurring once every year (a period of one year).

Combine prefix and base word

Applying the prefix semi- (happening once halfway through a specific time period) to "annual" (a one-year period) means the event occurs halfway through the year, resulting in a frequency of twice a year.

Evaluate the given options

• "once a year" corresponds to "annual."
• "twice a year" corresponds to "semiannual" (once every half-year).
• "twice a month" would correspond to "semimonthly."
• "every other year" corresponds to "biennial."

Answer:

• once a year
• twice a year (Correct answer)
• twice a month
• every other year
