Understanding Prefixes and Vocabulary

The question asks us to complete a sentence by choosing the correct prefix to attach to the word part "cise". Prefixes are letters or groups of letters added to the beginning of a word to change its meaning.

The sentence is: "The staircase rails were decorated with ______cise patterns of leaves and vines."

We need to find a prefix that, when combined with "cise", forms a meaningful word that fits the context of the sentence. The sentence describes the patterns on staircase rails as being decorated, suggesting they are detailed or well-defined.

Analyzing the Options for the Prefix

Let's look at the given options and see which one forms a valid English word when combined with "cise":

• criti + cise: "criticise" (or "criticize" in American English) means to evaluate and judge someone or something, often negatively. This word does not fit the context of decorating patterns.
• pre + cise: "precise" means marked by exactness and accuracy of expression or detail. This word describes something that is detailed, exact, and well-defined, which fits the description of patterns on decorations.
• ex + cise: "excise" means to cut out or remove something. This word does not fit the context of decorating patterns.
• in + cise: "incise" means to cut into a surface. While patterns can be incised, the word needed is likely an adjective describing the patterns themselves, not the action of creating them. "Incise" is a verb.

Identifying the Correct Word "Precise"

Based on the analysis, combining the prefix "pre" with "cise" forms the word "precise". The word "precise" is an adjective that means sharply defined or exact. This meaning perfectly fits the description of decorative patterns that are likely intricate, detailed, and well-executed.

Completing the Sentence

Using the word "precise", the completed sentence is:

"The staircase rails were decorated with precise patterns of leaves and vines."

This sentence makes sense and is grammatically correct.

Conclusion on the Correct Prefix

The prefix that correctly completes the word in the sentence and forms a word that fits the context is "pre". The resulting word is "precise".
