RAS question
What does CERN stand for?
Correct answer: (B) Conseil Européen pour la Recherche Nucléaire (European Council for Nuclear Research).
CERN stands for Conseil Européen pour la Recherche Nucléaire, meaning the European Council for Nuclear Research.
Explanation
CERN is best read through its original French name: Conseil Européen pour la Recherche Nucléaire, translated as the European Council for Nuclear Research. The official CERN page traces this wording to a UNESCO intergovernmental meeting in Paris in December 1951, where the first resolution for setting up a European Council for Nuclear Research was adopted. That name belongs to the organisation students know today as the European Organization for Nuclear Research, based near Geneva in Switzerland. Conseil Européen pour la Recherche Nucléaire is the only precise expansion of CERN because it gives both the French form behind the acronym and its English meaning. The broader context also fits CERN's role as the operator of the Large Hadron Collider, the world's largest particle accelerator.
Why the other options are wrong
- (A) Central Energy Research Network is wrong because CERN's official origin is tied to nuclear research, not a central energy network.
- (C) Combined European Reactor Network is wrong because the cited CERN history says the name came from a European Council for Nuclear Research, not a reactor network.
- (D) Centre for European Nuclear Research is wrong because it replaces the official French-derived council wording with a plausible but unofficial English phrase.
Concept
This tests science and technology institutions: RAS often asks full forms where the acronym preserves an older or non-English official name. CERN also recurs because it links basic nuclear and particle physics with a major international research organisation.
