English Idioms — Choose the correct meaning. Sentence: In the organised society of today, no individual or nation can plough a lonely furrow.

Introduction / Context:
The idiom “to plough a lonely furrow” comes from agriculture: a farmer ploughing alone creates an isolated furrow. Figuratively, it means to act independently, without support, often contrary to prevailing trends. In modern geopolitics and economics, the sentence argues that such complete independence is impractical.

Given Data / Assumptions:

• Idiom under test: plough a lonely furrow.
• Scope: applies to individuals and nations.
• We need the best paraphrase reflecting “acting alone without help.”

Concept / Approach:
Two options look close: “do without the help of others” and “survive in isolation.” The canonical gloss stresses proceeding or working without others’ help rather than the outcome of survival. Therefore, the more accurate operational paraphrase is “do without the help of others.”

Step-by-Step Solution:

Verification / Alternative check:
Paraphrase: “no individual or nation can do without the help of others.” This preserves the author’s claim and aligns with standard dictionary explanations of the idiom.

Why Other Options Are Wrong:

• remain unaffected: Not related to independence of action.
• survive in isolation: Outcome-focused; not the idiom’s primary emphasis.
• remain non-aligned: Political stance only; too narrow.

Common Pitfalls:
Equating independence with political “non-alignment.” The idiom is broader and operational—about proceeding alone without assistance.

Final Answer:
do without the help of others
