he Large Hadron Collider (LHC), located underneath the border of France and Switzerland, 1s currently the biggest experiment in the world. Its construction mvolved 9,000 magnets and over 10,000 tons of nitrogen are used for its cooling processes. Scientists and engineers have spent 4.5 billion on building an underground track at CERN, the worlds largest particle physics laboratory. This enormous scientific instrument will collect a huge amount of data, but only a small percentage of what is recorded will be useful. When proton atoms  travelling almost at light speed  collide inside the LHC, theoretical physicists expect new forces and particles to be produced. It may even be possible to study black holes using this experiment.
Question: The cost of the LHCs track was over 4.5 billion.
Options:
A. true
B. false
C. uncertain
