The prefix "un-" is used to indicate the opposite or absence of a quality or condition. It is commonly used to form words that express negation or denial.

All of the above words use the prefix "un-" correctly. The prefix "un-" is used to indicate the opposite or absence of the root word. In the case of "unreal," it means not real, in "unhappy," it means not happy, and in "unacceptable," it means not acceptable. Therefore, all of these words are formed correctly by adding the prefix "un-" to their respective root words.

The prefix re- means to do again or to go back. In the word READ, the prefix re- is not used to indicate repetition or going back. Therefore, the statement that the prefix re- is correctly used in the word READ is false.
8.
Which of the following words uses the prefix re- correctly?
Correct Answer
C. React
Explanation
The word "react" uses the prefix "re-" correctly because it means to respond or behave in a particular way as a result of a stimulus or situation. The prefix "re-" in "react" indicates a repetition or return to a previous state, which aligns with the meaning of the word.
9.
The prefix de- means ________________ or _____________.
Correct Answer
opposite, remove
remove, opposite
Explanation
The prefix "de-" has two meanings: opposite and remove. When added to a word, it can either indicate the opposite of the original meaning or the act of removing something. For example, "devalue" means to reduce the value of something, while "defrost" means to remove frost from an object.
10.
The prefix de- is used incorrectly in the word dead.
Correct Answer
A. True
Explanation
The prefix "de-" is used to indicate negation or reversal. However, in the word "dead," the prefix "de-" is not used correctly because "dead" is not the opposite of anything. "Dead" means no longer alive, so it does not require the prefix "de-" to convey a negative or reversed meaning. Therefore, the statement is true.
11.
Which of the following words use the prefix de- correctly?
Correct Answer
D. All of the above
Explanation
The prefix "de-" means to reverse or remove. In all of the given words, the prefix "de-" is used correctly. In "delay," it means to cause a reversal or postponement. In "debrief," it means to remove or extract information. In "decrease," it means to reduce or make less. Therefore, all of the above words use the prefix "de-" correctly.
12.
Prefixes are (sometimes, always, or never) put in front of a root word to create a new word.
Correct Answer
always
Explanation
Prefixes are always put in front of a root word to create a new word. A prefix is a group of letters added to the beginning of a word to change its meaning or create a new word. This is a rule in the English language, where prefixes are consistently used to modify or enhance the meaning of a root word. Therefore, the statement "always" accurately describes the relationship between prefixes and root words.
