Question

using a prefix to determine meaning
read the sentence and study the table.
the women’s club held fundraisers on a semiannual basis.

prefix | meaning
semi- | half in value; happening once halfway through a specific time period

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:

The prefix "semi - " means half or happening once halfway through a time period. The word "semiannual" has the prefix "semi - " and the root "annual" (related to a year). So combining the meaning of the prefix and the root, "semiannual" should mean happening twice a year (since half of a year - long period, and over a year, it would be twice). "Once a year" is "annual", "twice a month" would be related to a monthly period with "semi - " not fitting, and "every other year" is "biennial".

Answer:

twice a year
