     "This histogram gives us a snapshot of the lepton content in the events, which can be further analyzed to study processes like lepton production in proton-proton collisions at high energies. The distribution is an important aspect of understanding the data and may inform further cuts or selection criteria for a complex physics analysis.\n",

-    "In this example, as always, it is a good idea to see if the result matches your intuition. Here we began with a sample of Z bosons decaying to electrons, so it makes good sense that most events contain exactly two electrons. Can you think of some reasons why there might be only one or three in some events? The file we selected has **1LMET30** in the name, meaning that the events in it were pre-selected to have at least one lepton. That also helps explain why there are so few zero-electron events. If you would like, you can try picking a file from a [different sample](https://opendata.atlas.cern/docs/data/for_education/13TeV25_metadata) to see how the result changes.\n",
