Understanding the Passage and the Question

The question asks us to fill in the blanks in a given passage about posters. We need to read the passage carefully and choose the most appropriate word from the options for each blank. Specifically, we are asked to select the best option for blank number 3.

Analyzing Blank 3

Let's look at the sentence containing blank 3:

"They can be used for (3) __________ purposes ranging from telling people to be cautious as the floor is wet, to informing them about an upcoming sale or event."

The sentence provides examples of the different uses of posters: giving a caution (wet floor) and providing information (sale/event). These examples show that posters are used for many different kinds of communication needs.

Evaluating the Options for Blank 3

Let's consider the provided options for blank 3:

• little
• varied
• much
• similar

Now, let's test each option in the sentence:

1. "They can be used for little purposes..." - 'little' suggests a small number or amount. This doesn't fit the idea of posters being used for things "ranging from...to", which implies a breadth of uses.
2. "They can be used for varied purposes..." - 'varied' means many different types or kinds. The examples (caution, information about sale/event) clearly show different types of purposes. This option fits well with the phrase "ranging from...to".
3. "They can be used for much purposes..." - 'much' is usually used with uncountable nouns. 'purposes' is a countable noun. Grammatically, 'much' is incorrect here; 'many' would be used for countable nouns, but even 'many' wouldn't capture the *type* difference implied by the examples as well as 'varied' does.
4. "They can be used for similar purposes..." - 'similar' means alike or almost the same. The examples (caution about wet floor vs. information about a sale) are not similar; they are quite different in nature and intent. This option contradicts the examples given.

Determining the Most Appropriate Word

Based on the analysis, the word that best describes the range and difference in the types of purposes for which posters are used, as illustrated by the examples provided in the passage, is "varied". It accurately reflects that posters serve many different kinds of purposes, from safety warnings to event announcements.

Therefore, the most appropriate option to fill in blank number 3 is "varied".

Final Answer Selection for Blank 3

The most appropriate word for blank no. 3 is 'varied'.

• Target Audience: Designed with specific viewers in mind.
• Visuals: Often include images or graphics to grab attention.
