Question #N420

The discovery of the Higgs boson particle, a fundamental particle that gives mass to other particles, was announced in 2012. Scientists at CERN, the European Organization for Nuclear Research, had been searching for the Higgs boson for decades, and they had built the Large Hadron Collider, a massive particle accelerator, to help in their search. The Higgs boson was the last particle predicted by the Standard Model of particle physics to be found. The discovery of the Higgs boson is considered to be a major milestone in our understanding of the universe.

The main idea of the passage is that

A. the Higgs boson was discovered in 2012 at CERN, the European Organization for Nuclear Research.
