I have list A with elements `{China China USA USA ITALY FRANCE}` and list B with elements `{2018 2017 2018 2017 2018 2017}`

I want to check for element 2018 in list `B` and, once it is found, to return the corresponding element from list `A`.

With the found, elements I will populate list `C`. So the desired result is list `C` with elements `{China, USA, ITALY}`.
