In the same paragraph about literature and social protest, select the word that best completes the third blank: "The words that deal with a _____ issue are of particular importance in literature."

Introduction / Context:
The paragraph under discussion explains how literature allows a person to convey ideas and protest against social norms. It then focuses on certain kinds of issues that are especially significant in literary works. This question asks you to choose the adjective that best describes the type of issue that gives particular importance to words in literature.

Given Data / Assumptions:

• The key sentence is: The words that deal with a _____ issue are of particular importance in literature.
• The context is literature addressing norms and protests in society.
• The options available are broad, insensitive, moral, economical and general.
• We assume that the issue in question relates to values and right or wrong behaviour in society.

Concept / Approach:
When literature protests against social norms, it often deals with questions of right and wrong, justice, fairness and ethical behaviour. Such questions are commonly described as moral issues. The phrase moral issue is a standard collocation in English and appears frequently in essays, debates and analysis of literature. Describing an issue as broad or economical does not naturally convey the ethical focus. Insensitive and general also do not match the nuance of deep questions about good and bad that literature frequently explores.

Step-by-Step Solution:
Step 1: Recognise that the paragraph talks about norms of society and protest, which relate to values and ethics.
Step 2: Recall the common expression moral issue to describe questions of right and wrong.
Step 3: Fit each option into the sentence and test for meaning and naturalness: a broad issue, an insensitive issue, a moral issue, an economical issue, a general issue.
Step 4: Observe that a moral issue clearly connects with literature that questions or challenges social norms.
Step 5: Select moral as the word that best completes the sentence.

Verification / Alternative check:
In critical discussions we often read lines such as The novel raises important moral issues about inequality or The play explores the moral issue of responsibility. These examples show that moral issue is a widely accepted phrase. On the other hand, calling these topics economical issues would shift attention to financial aspects, and insensitive issue is not a standard phrase. Broad issue is too vague, and general issue does not add any specific meaning. The context of norms and protest strongly points to questions of morality, confirming moral as the correct choice.

Why Other Options Are Wrong:
Option A, broad, simply refers to something wide in scope and does not highlight ethical concern. Option B, insensitive, describes a lack of feeling or awareness rather than the nature of an issue itself. Option D, economical, is associated with finance, savings or the economy, and does not match the theme of social values. Option E, general, is too weak and unspecific to describe issues that are of particular importance in literature. Therefore, none of these capture the intended idea as accurately as moral.

Common Pitfalls:
Learners may choose broad because many literary works do deal with wide ranging topics, but the phrase broad issue lacks the sharp focus on ethics that the context demands. Another trap is economical, as some may loosely connect it with social questions, but the paragraph clearly emphasises norms and protest, which more naturally point to moral debates. Training yourself to listen for standard collocations like moral issue, social justice, human rights and ethical dilemma will make it much easier to handle vocabulary based questions of this type.

Final Answer:
The correct word is moral, giving the sentence: The words that deal with a moral issue are of particular importance in literature.
