In the following vocabulary question, choose the word which is closest in meaning to the given word:\n\nRequisite.

Introduction / Context:
This vocabulary question asks you to identify a synonym for the word requisite. In examination English, requisite is often used as an adjective meaning necessary or required for a particular purpose. Therefore, the correct option should express the idea of something that must be present or fulfilled before something else can happen.

Given Data / Assumptions:

• Target word: requisite.
• Options: Peripheral, Deadwood, Trivial, Precondition.
• We interpret requisite as something that is essential or required.

Concept / Approach:
Precondition means a condition that must be fulfilled before other things can happen or be possible. This meaning closely matches requisite when used as a noun or in the sense of required condition. The other options describe things that are unimportant, unnecessary, or marginal, which are opposite to what requisite suggests. So Precondition is the best synonym here.

Step-by-Step Solution:
Step 1: Recall that requisite refers to something that is necessary or essential. Step 2: Compare that meaning with each option. Step 3: Notice that precondition describes a necessary condition for something else to occur. Step 4: Select Precondition as the word closest in meaning to requisite.

Verification / Alternative check:
Use both words in a similar sentence. For example, Experience in accounting is a requisite for this job. Experience in accounting is a precondition for this job. Both sentences communicate that experience is required, not optional. In contrast, Experience in accounting is peripheral or deadwood or trivial changes the meaning in the wrong direction, as those words suggest something unimportant or useless.

Why Other Options Are Wrong:
Option A, Peripheral, means on the edge or not central, often implying that something is of minor importance. Option B, Deadwood, refers to people or things that are no longer useful or productive. Option C, Trivial, means unimportant or insignificant. All of these words indicate the opposite of necessary or required, so they are not correct synonyms for requisite.

Common Pitfalls:
A common mistake is to focus only on rough associations, such as thinking of any formal sounding word as a synonym. However, you must match the core meaning carefully. Requisite deals with necessity, whereas peripheral and trivial deal with lack of importance. Learning words in meaningful groups, such as required, essential, necessary, and precondition, can help avoid such confusion.

Final Answer:
The word that is closest in meaning to requisite is Precondition.
