Topic/ subject + controlling idea [closed]

Can someone help me identify the subject + the controlling idea of this sentence.

If you’ve ever dreamed of exploring Andalucia, Catalonia, or Mallorca, we invite you to explore Spain on a bike tour with us.

Thank you,


The subject of the sentence is we. The topic (what the sentence is about) is exploring Spain on a bike tour. The controlling idea is "Only open to those who really want to visit the three regions mentioned".
