Read the passage given below and answer the question/complete the statement that follows by choosing the correct options from the given ones.
1. Cycling to work may seem the healthy options, but a study has shown that people riding in cities inhale tens of millions of toxic nanoparticles with every breath, at least five times more than drivers or pedestrians.
2. The research showed that urban concentrations of nanoparticles, which measure just a few millions of a millimeter, could reach several hundred thousand in a cubic centimeter of air. The particles, when inhaled, have been linked to heart disease and respiratory problems.
3. Because they are exerting themselves, cyclists breathe harder and faster than other road users. The study found that they suck in about 1,000 cubic cm with each breath, meaning they may inhale tens of millions of particles each time they fill their lungs and billions during a whole journey.
4. This is the first time anyone has counted the particles while also measuring people's breathing during city commuting. It showed that cyclists can inhale an astonishing number of pollutant particles in one journey.
5. For the research, Int Panis and his colleagues asked cyclists to pedal while wearing a mask fitted with instruments that could count the particulates, as the particles are known.
6. The researchers found that in Brussels the cyclists inhaled 5.58 million nanoparticles for every meter cycled, dropping to 1.1 million when they tried the experiment in Mol, a smaller town in Belgium. They also found that the cyclists inhaled 4.5 times more particles than a car passenger driven along the same route.
