example:
College enrollment figures for the past fifteen years show that less students
are now choosing to major in fields such as sociology and history
Which underlined word or phrase must be changed for the sentence to be correct? If you chose
less students, you were correct Since you can count students, you must use the correct expression
of quantity: fewer students
Other structures that may be tested include:
Countable nouns:
The hosta is a type of flowering plant that thrives in the shade
Mark Twain said there are three kinds of lies: lies, damned lies, and statistics

Some TOEFL items contain numbers used as nouns or adjectives When numbers are used as
nouns, they can be plural, taking the —s/es ending In general, adjectives do not have plural
forms When numbers are adjectives, they do not take the —s/es ending
Look at some examples of correct and incorrect plurals in phrases involving numbers:
Note: When a number is used with percent, such as in fifty percent or one hundred percent,
percent takes the singular form
A TOEFL item may test you by having an incorrect singular or plural form in a phrase involving
numbers Look at this example:
Generally, twelve—vears—old girls are taller and heavier than boys of that age
Which underlined word or phrase must be changed for the sentence to be correct? If you chose
twelve—years—old, you were correct because it is an adjective modifying girls Adjectives do not
have plural forms Correction: twelve—year—old girls
Note: The following are correct:
The girls are twelve years old
They are twelve—year—old girls
Look at another example:
With a wing span of almost nine foot, the majestic California condor
is the largest of the western birds of prey
Which underlined word or phrase must be changed for the sentence to be correct? If you chose
almost nine foot, you were correct because foot is a noun in this context The noun foot has an
irregular plural Correction: almost nine feet

a team has a surplus of one type of card, it can trade with another team The first team
to correctly pair all of their cards wins the game
