Luca wants to identify and quantify the chemicals causing air pollution in a city, but he is using a manual air sampler to collect air samples.

Why should he update his current sampler to an electronic one?

to maintain the current way air sampling data are stored
to diagram exactly what portions of the city are affected by air pollution
to make predictions about air pollution that are precise but not accurate
to account for broad-scale factors that affect the number of chemicals identified
