How did the Second International make the workers' movement an international issue from a national issue?

Correct answer: It gave a common platform to socialist and labour organizations of different countries

The direct answer is A: the Second International gave socialist and labour organisations from different countries a common platform. A workers’ struggle can remain national when workers act only within one country. The Second International helped them communicate, discuss common problems, coordinate campaigns, and develop international solidarity. The reasoning is: industrial workers in many countries faced related problems; separate organisations met through an international body; their concerns were therefore discussed across national borders. Option A is correct because it directly explains how a national movement became linked with international socialism. Option B is wrong because connecting workers from only one city would not make a movement international. Option C is wrong because the organisation was associated with socialist and labour movements, not a secret meeting of kings. Option D is wrong because it did not remove workers from politics; it encouraged political discussion and collective action. The word “different countries” is the strongest clue in the question. Memory cue: Second International means workers’ organisations joining across borders, not a government alliance or a single-city union.
